技术领域Technical Field
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及存储介质。The present application relates to the field of communication technology, and in particular to a communication method, device and storage medium.
背景技术Background technique
国际电信联盟(international telecommunication union，ITU)为第五代移动通信系统(the fifth generation，5G)以及未来的移动通信系统定义了多种应用场景，例如：增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultrareliable and low latency communications，URLLC)以及海量机器类通信(massivemachine type communications，mMTC)。The International Telecommunication Union (ITU) has defined a variety of application scenarios for the fifth generation (5G) and future mobile communication systems, such as enhanced mobile broadband (eMBB), ultrareliable and low latency communications (URLLC), and massive machine type communications (mMTC).
在不同的应用场景下，通常采用混合自动重传请求(hybrid automatic repeatrequest，HARQ)反馈机制来保证网络设备与终端设备之间数据传输的可靠性。由于HARQ反馈机制可以在数据传输失败时请求网络设备重传，从而可保证数据传输的可靠性。而且，HARQ反馈机制中发送端是在接收到接收端反馈NACK时，才会重传数据，进而也可降低数据传输整体资源消耗。但是，当通信系统中有大量的终端设备同时向网络设备发送反馈信息时，会造成通信系统开销非常大。例如在第三代合作伙伴计划(3rd generationpartnership project，3GPP)中提出的多媒体广播多播业务(multimedia broadcastmulticast service，MBMS)，若所有的终端设备都向网络设备发送反馈信息，造成系统开销也非常大，因此，目前MBMS不支持HARQ反馈机制。In different application scenarios, a hybrid automatic repeat request (HARQ) feedback mechanism is usually used to ensure the reliability of data transmission between network devices and terminal devices. Since the HARQ feedback mechanism can request the network device to retransmit when data transmission fails, the reliability of data transmission can be guaranteed. Moreover, in the HARQ feedback mechanism, the sender will retransmit the data only when it receives the NACK feedback from the receiver, which can also reduce the overall resource consumption of data transmission. However, when a large number of terminal devices in the communication system send feedback information to the network device at the same time, the communication system overhead will be very large. For example, in the multimedia broadcast multicast service (MBMS) proposed in the3rd generation partnership project (3GPP), if all terminal devices send feedback information to the network device, the system overhead will also be very large. Therefore, MBMS currently does not support the HARQ feedback mechanism.
发明内容Summary of the invention
本申请提供一种通信方法、装置及存储介质，用于减小通信系统的反馈开销。The present application provides a communication method, an apparatus, and a storage medium for reducing feedback overhead of a communication system.
第一方面，本申请提供一种通信方法，该方法包括接收来自网络设备的分组信息，以及接收来自网络设备的第一数据，确定第一数据所属的第一分组，并根据第一分组对应的指示信息确定是否需要向网络设备发送反馈信息，其中，第一分组为一个或多个分组中的一个，分组信息指示一个或多个分组包括的第一标识，分组信息还包括各分组对应的指示信息。应理解，第一标识可标识一个业务，也可以标识一组业务。In a first aspect, the present application provides a communication method, the method comprising receiving group information from a network device, and receiving first data from the network device, determining a first group to which the first data belongs, and determining whether feedback information needs to be sent to the network device according to indication information corresponding to the first group, wherein the first group is one of one or more groups, the group information indicates a first identifier included in the one or more groups, and the group information also includes indication information corresponding to each group. It should be understood that the first identifier can identify a service or a group of services.
该方法可由通信装置执行，通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片系统。示例性地，通信设备为终端设备。The method may be performed by a communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system. Exemplarily, the communication device is a terminal device.
基于该方案，通过将多个业务分组，并为各分组配置指示信息，可实现有些分组需要向网络设备发送反馈信息，即开启反馈机制，有些业务不需要向网络设备发送反馈信息，即未开启(或者已关闭)反馈机制。对于接收到属于未开启反馈机制的分组中的第一数据后，不论是否正确解析该第一数据，都不需要向网络设备发送任何反馈信息，如此，有助于减少通信系统的反馈开销。例如，当将业务传输可靠性需求高的业务分为一个分组，并为该分组配置开启反馈机制，如可，可保证该分组中业务数据的传输高可靠性需求。Based on this solution, by grouping multiple services and configuring indication information for each group, it can be achieved that some groups need to send feedback information to the network device, that is, the feedback mechanism is turned on, and some services do not need to send feedback information to the network device, that is, the feedback mechanism is not turned on (or has been turned off). After receiving the first data in the group that does not have a feedback mechanism turned on, no matter whether the first data is correctly parsed, it is not necessary to send any feedback information to the network device, which helps to reduce the feedback overhead of the communication system. For example, when a service with a high service transmission reliability requirement is divided into a group, and the feedback mechanism is turned on for the group, if possible, the high reliability requirement for the transmission of the service data in the group can be guaranteed.
本申请中指示信息包括但不限于以下六种情形中的任一种。The indication information in this application includes but is not limited to any one of the following six situations.
情形1，指示信息包括第一类参数，其中，第一类参数用于表示反馈或不反馈。In case 1, the indication information includes a first type of parameter, wherein the first type of parameter is used to indicate feedback or no feedback.
情形2，指示信息包括第二类参数，其中，第二类参数用于表示反馈判决参数的门限。在确定第一数据对应的反馈判决参数的值满足反馈判决参数的门限时，向网络设备发送反馈信息；或者，在确定第一数据对应的反馈判决参数的值不满足反馈判决参数的门限时，不向网络设备发送反馈信息。应理解，满足包括但不限于大于，小于，大于或等于，小于或等于，在某一范围内等。In case 2, the indication information includes a second type of parameter, wherein the second type of parameter is used to indicate a threshold of a feedback decision parameter. When it is determined that the value of the feedback decision parameter corresponding to the first data satisfies the threshold of the feedback decision parameter, feedback information is sent to the network device; or, when it is determined that the value of the feedback decision parameter corresponding to the first data does not satisfy the threshold of the feedback decision parameter, feedback information is not sent to the network device. It should be understood that satisfying includes but is not limited to greater than, less than, greater than or equal to, less than or equal to, within a certain range, etc.
可选地，反馈判决参数包括以下内容中任一项或任多项的组合：距离、参考信号接收功率(reference signal receiving power，RSRP)、信号与干扰加噪声比(signal tointerference plus noise ratio，SINR)。也就是说，反馈判决参数可以是距离，或者是RSRP，或者是SINR，或者是距离和RSRP，或者是距离和SINR，或者是RSRP和SINR，或者是距离、RSRP和SINR。需要说明的是，距离可以指地理距离。需要说明的是，当反馈判决参数为距离时，确定当前实际距离(即第一数据对应的反馈判决参数的值)在距离范围(反馈判决距离的门限)内反馈，可以是默认的；或者也可以是网络设备通知的(例如可以是预先通知的，或者随指示信息一起发送至的)；或者也可以是与网络设备预先约定的，或者也可以是协议预定义的。类似地，确定当前实际距离小于反馈判决距离的门限时反馈，或者大于反馈判决距离的门限时反馈，可以是默认的；或者也可以是网络设备通知的；或者也可以是与网络设备预先约定的，或者也可以是协议预定义的。当前RSRP的值(即第一数据对应的反馈判决参数的值)小于RSRP的门限不反馈，或者大于RSRP的门限反馈，可以是默认的，也可以是网络设备预先通知的，或者也可以是协议预定义的。当反馈判决参数为SINR，确定当前SINR的值(即第一数据对应的反馈判决参数的值)小于SINR的门限不反馈，大于SINR的门限反馈，可以是默认的，也可以是网络设备预先通知的，或者也可以是协议预定义的。Optionally, the feedback decision parameter includes any one or a combination of any two of the following: distance, reference signal receiving power (RSRP), signal to interference plus noise ratio (SINR). That is, the feedback decision parameter may be distance, or RSRP, or SINR, or distance and RSRP, or distance and SINR, or RSRP and SINR, or distance, RSRP and SINR. It should be noted that the distance may refer to the geographical distance. It should be noted that when the feedback decision parameter is distance, it is determined that the current actual distance (i.e., the value of the feedback decision parameter corresponding to the first data) is fed back within the distance range (the threshold of the feedback decision distance), which may be by default; or it may be notified by the network device (for example, it may be notified in advance, or sent to together with the indication information); or it may be pre-agreed with the network device, or it may be pre-defined by the protocol. Similarly, it is determined that the feedback is fed back when the current actual distance is less than the threshold of the feedback decision distance, or it is fed back when it is greater than the threshold of the feedback decision distance, which may be by default; or it may be notified by the network device; or it may be pre-agreed with the network device, or it may be pre-defined by the protocol. The current RSRP value (i.e., the value of the feedback decision parameter corresponding to the first data) is less than the RSRP threshold and is not fed back, or is greater than the RSRP threshold and is fed back, which can be by default, or can be notified in advance by the network device, or can be predefined by the protocol. When the feedback decision parameter is SINR, determining that the current SINR value (i.e., the value of the feedback decision parameter corresponding to the first data) is less than the SINR threshold and is not fed back, or is greater than the SINR threshold and is fed back, can be by default, or can be notified in advance by the network device, or can be predefined by the protocol.
情形3，指示信息包括第一类参数和第二类参数，其中，第一类参数和第二类参数可参见上述情形1和情形2的介绍。In case 3, the indication information includes first-category parameters and second-category parameters, wherein the first-category parameters and the second-category parameters can refer to the introduction of the above-mentioned cases 1 and 2.
当指示信息为上述情形3时，第一分组对应的指示信息可以包括第一类参数和第二类参数，确定第一数据所属的第一分组对应的第一类参数表示反馈、且第一数据对应的反馈判决参数的值满足反馈判决参数的门限时，向网络设备发送反馈信息。When the indication information is the above-mentioned situation 3, the indication information corresponding to the first group may include first-category parameters and second-category parameters. When it is determined that the first-category parameter corresponding to the first group to which the first data belongs represents feedback, and the value of the feedback decision parameter corresponding to the first data meets the threshold of the feedback decision parameter, feedback information is sent to the network device.
在一种可能的实现方式中，第一标识可为临时移动组标识(temporary mobilegroup identity，TMGI)、组无线网络临时标识(group-radio network temporaryidentifier，G-RNTI)、多播控制信道(multicast control channel，MCCH)、或单小区多播控制信道(single cell multicast control channel，SC-MCCH)。In one possible implementation, the first identifier may be a temporary mobile group identity (TMGI), a group-radio network temporary identifier (G-RNTI), a multicast control channel (MCCH), or a single cell multicast control channel (SC-MCCH).
应理解，当执行上述方法的通信装置处于无线资源控制(radio resourcecontrol，RRC)连接态时，第一标识可为G-RNTI；当执行上述方法的通信装置处于空闲(IDLE)态时，第一标识可为TMGI、SC-MCCH或MCCH。具体可选地，第一标识为SC-MCCH还是为MCCH，可由MBMS的传输方式来确定，例如，当MBMS为多媒体广播单频网(multimediabroadcast single frequency network，MBSFN)传输方式时，第一标识为MCCH；当MBMS为单小区点到多点(single cell point-to-multipoint，SC-PTM)传输方式时，第一标识为SC-MCCH。It should be understood that when the communication device executing the above method is in a radio resource control (RRC) connection state, the first identifier may be G-RNTI; when the communication device executing the above method is in an idle (IDLE) state, the first identifier may be TMGI, SC-MCCH or MCCH. Specifically, whether the first identifier is SC-MCCH or MCCH can be determined by the transmission mode of MBMS. For example, when MBMS is a multimedia broadcast single frequency network (MBSFN) transmission mode, the first identifier is MCCH; when MBMS is a single cell point-to-multipoint (SC-PTM) transmission mode, the first identifier is SC-MCCH.
为了进一步减小通信系统的反馈开销，在确定需要向网络设备发送反馈信息，且确定反馈信息满足反馈条件时，向网络设备发送反馈信息，其中，反馈条件为：未正确解析第一数据。In order to further reduce the feedback overhead of the communication system, when it is determined that feedback information needs to be sent to the network device and it is determined that the feedback information meets the feedback condition, the feedback information is sent to the network device, wherein the feedback condition is: the first data is not correctly parsed.
本申请中，反馈信息可以是HARQ反馈信息，或者也可以是CSI，或者也可以是HARQ反馈信息和CSI。具体反馈信息是哪种，可以是网络设备通知给的，也可以是网络设备与预先约定的，或者也可以是默认的，或者也可以通过协议预定义的。In the present application, the feedback information may be HARQ feedback information, or CSI, or HARQ feedback information and CSI. The specific feedback information may be notified by the network device, or agreed upon in advance by the network device, or defaulted, or predefined by the protocol.
第二方面，本申请提供一种通信方法，该方法包括为各分组配置指示信息，向终端设备发送分组信息，分组信息指示一个或多个分组包括的第一标识，分组信息还包括各分组对应的指示信息。应理解，一个分组中可包括一个或多个第一标识。In a second aspect, the present application provides a communication method, the method comprising configuring indication information for each group, sending group information to a terminal device, the group information indicating a first identifier included in one or more groups, and the group information also including indication information corresponding to each group. It should be understood that a group may include one or more first identifiers.
该方法可由通信装置执行，通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片系统。示例性地，通信设备为网络设备。The method may be performed by a communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip system. Exemplarily, the communication device is a network device.
基于该方案，通过将多个业务分组，并为各分组配置指示信息，可实现有些分组需要发送反馈信息，即开启反馈机制；有些业务不需要发送反馈信息，即未开启(或者已关闭)反馈机制。对于终端设备接收到属于未开启反馈机制的分组中的第一数据后，不论是否正确解析该第一数据，都不需要发送任何反馈信息。如此，有助于减少通信系统的反馈开销(除有用的数据外的控制信息均被称为开销)。例如，当将业务传输可靠性需求高的业务分为一个分组，并为该分组配置开启反馈机制，如可，可保证该分组中业务数据的传输高可靠性需求。Based on this solution, by grouping multiple services and configuring indication information for each group, it can be achieved that some groups need to send feedback information, that is, the feedback mechanism is turned on; some services do not need to send feedback information, that is, the feedback mechanism is not turned on (or has been closed). After the terminal device receives the first data in the group that does not have a feedback mechanism turned on, no matter whether the first data is parsed correctly or not, it is not necessary to send any feedback information. In this way, it helps to reduce the feedback overhead of the communication system (control information other than useful data is called overhead). For example, when a service with a high service transmission reliability requirement is divided into a group, and the feedback mechanism is turned on for the group, if possible, the high reliability requirement for the transmission of the service data in the group can be guaranteed.
各分组可以是网络设备对多个业务进行分组得到的，也可以直接将已完成分组的各分组存储于网络设备中。Each group may be obtained by grouping a plurality of services by the network device, or each grouped group may be directly stored in the network device.
在一种可能的实现方式中，可根据多个业务的业务特性和/或业务类型，对多个业务分组。也就是说，可以根据业务特性对多个业务分组，也可根据业务类型对多个业务分组，或者也可根据业务类型和业务特性对多个业务分组。其中，业务特性包括业务可靠性需求、业务覆盖能力、业务时延需求、业务数据量、业务移动性需求和业务优先级中的任一项或任多项的组合；业务类型包括增强型移动宽带eMBB、高可靠低时延通信URLLC、海量机器类通信mMTC、车联网(vehicle to everything，V2X)、物联网(internet of things，IoT)中的任一项。In one possible implementation, multiple services may be grouped according to service characteristics and/or service types of multiple services. That is, multiple services may be grouped according to service characteristics, or may be grouped according to service types, or may be grouped according to service types and service characteristics. Among them, service characteristics include any one or a combination of multiple items of service reliability requirements, service coverage capabilities, service latency requirements, service data volume, service mobility requirements, and service priority; service types include any one of enhanced mobile broadband eMBB, highly reliable and low latency communication URLLC, massive machine type communication mMTC, vehicle to everything (V2X), and Internet of Things (IoT).
在一种可能的实现方式中，第一标识为TMGI、G-RNTI、MCCH、或SC-MCCH。应理解，当终端设备处于无线资源控制(radio resource control，RRC)连接态时，第一标识可为G-RNTI；终端设备处于空闲(IDLE)态时，第一标识可为TMGI、SC-MCCH或MCCH。具体可选地，第一标识为SC-MCCH还是为MCCH，可由MBMS的传输方式来确定，例如，当MBMS为多媒体广播单频网(multimedia broadcast single frequency network，MBSFN)传输方式时，第一标识为MCCH；当MBMS为单小区点到多点(single cell point-to-multipoint，SC-PTM)传输方式时，第一标识为SC-MCCH。In one possible implementation, the first identifier is TMGI, G-RNTI, MCCH, or SC-MCCH. It should be understood that when the terminal device is in a radio resource control (RRC) connection state, the first identifier may be G-RNTI; when the terminal device is in an idle (IDLE) state, the first identifier may be TMGI, SC-MCCH or MCCH. Specifically, optionally, whether the first identifier is SC-MCCH or MCCH can be determined by the transmission mode of MBMS. For example, when MBMS is a multimedia broadcast single frequency network (MBSFN) transmission mode, the first identifier is MCCH; when MBMS is a single cell point-to-multipoint (SC-PTM) transmission mode, the first identifier is SC-MCCH.

The first type of parameters are used to indicate feedback or no feedback; the second type of parameters are used to indicate the threshold of the feedback decision parameter, and the threshold of the feedback decision parameter is used to: send feedback information when it is determined that the value of the feedback decision parameter corresponding to the first data meets the threshold of the feedback decision parameter; or not send feedback information when it is determined that the value of the feedback decision parameter corresponding to the first data does not meet the threshold of the feedback decision parameter.
或者指示信息还可包括预设条件，该预设条件可为大于SINR的门限时反馈，或者大于RSRP的门限时反馈，或者落在某一距离范围(即距离的门限)时反馈，等等。Or the indication information may also include a preset condition, which may be feedback when the SINR is greater than a threshold, or feedback when the RSRP is greater than a threshold, or feedback when it falls within a certain distance range (ie, a distance threshold), and so on.

具体实施方式Detailed ways
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
图1示例性示出了本申请提供的一种通信系统架构示意图，该通信系统可以包括网络设备和终端设备。图1中以包括一个网络设备101和两个终端设备102为例说明。其中，网络设备101可通过无线的方式与终端设备102进行通信，主要是利用Uu空口传输。终端设备102之间可通过无线的方式进行通信，主要是利用侧行链路(Sidelink，SL)空口传输，也可称为设备到设备(device-to-device，D2D)之间的通信，例如V2X通信系统中V2V、V2P和V2I之间通过侧行链路直接通信，其中，侧行链路是针对通信设备和通信设备之间直接通信定义的，也就是说通信设备和通信设备之间的通信不需要通过网络设备的转发。FIG1 exemplarily shows a schematic diagram of a communication system architecture provided by the present application, and the communication system may include a network device and a terminal device. FIG1 is taken as an example including a network device 101 and two terminal devices 102. Among them, the network device 101 can communicate with the terminal device 102 in a wireless manner, mainly using the Uu air interface transmission. The terminal devices 102 can communicate with each other in a wireless manner, mainly using the sidelink (SL) air interface transmission, which can also be called device-to-device (D2D) communication, such as direct communication between V2V, V2P and V2I in the V2X communication system through the sidelink, wherein the sidelink is defined for direct communication between communication devices, that is, the communication between communication devices does not need to be forwarded by network devices.
其中，1)网络设备与终端设备之间通信主要是上行信号的传输和下行信号的传输。对于下行信号的传输，发送端是网络设备，对应的接收端是终端设备。对于上行信号的传输，发送端是终端设备，对应的接收端是网络设备。终端设备与终端设备之间通信主要是D2D的信号传输，发送端是终端设备，对应的接收端也是终端设备。本申请对信号的传输方向不做限定。Among them, 1) the communication between the network device and the terminal device is mainly the transmission of uplink signals and downlink signals. For the transmission of downlink signals, the sending end is the network device, and the corresponding receiving end is the terminal device. For the transmission of uplink signals, the sending end is the terminal device, and the corresponding receiving end is the network device.

The base station can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The RSU may be a fixed infrastructure entity that supports V2X applications and may exchange messages with other entities that support V2X applications. The access network equipment may also coordinate the attribute management of the air interface.

If located on a vehicle (for example, placed in a vehicle or installed in a vehicle), it can be considered as a vehicle-mounted terminal device, which is also called an on-board unit (OBU).

本申请中，通信系统可以是全球移动通信系统(global system for mobilecommunication，GSM)、码分多址(codedivision multiple Access，CDMA)系统、宽带码分多址(wideband code divisionmultiple access，WCDMA)系统，全球微波互联接入(worldwide interoperability formicrowave access，WiMAX)系统、长期演进(long termevolution，LTE)系统，5G通信系统(例如新空口(new radio，NR)系统、多种通信技术融合的通信系统(例如LTE技术和NR技术融合的通信系统)，还可以是其他通信系统，例如公共陆地移动网络(public land mobile network，PLMN)系统，或未来可能出现的其他通信系统等，本申请不做限定。In the present application, the communication system may be a global system for mobile communication (GSM), a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) system, a world-wide interoperability for microwave access (WiMAX) system, a long term evolution (LTE) system, a 5G communication system (such as a new radio (NR) system, a communication system integrating multiple communication technologies (such as a communication system integrating LTE technology and NR technology), or other communication systems, such as a public land mobile network (PLMN) system, or other communication systems that may appear in the future, etc., which are not limited in the present application.
本申请中，通信系统支持HARQ反馈机制。HARQ反馈机制具体指：若终端设备成功接收到来自网络设备的业务数据，则终端设备可在上行链路上进行HARQ-ACK反馈，即终端设备向网络设备发送的反馈信息为ACK；若终端设备未成功接收(如丢包、译码失败等)到来自网络设备的业务数据，则终端设备在上行链路上进行HARQ-NACK反馈，即终端设备向网络设备发送的反馈信息为NACK。当网络设备接收到终端设备反馈的是NACK且重传次数尚未达到最大重传次数时，网络设备随后可向终端设备重新发送上次传输的业务数据，终端设备可以将再次接收到的该业务数据与之前没有成功接收的业务数据进行合并来提升接收性能。也就是说，HARQ反馈机制可以在传输失败时请求重传，可提高数据传输的可靠性。In the present application, the communication system supports the HARQ feedback mechanism. The HARQ feedback mechanism specifically refers to: if the terminal device successfully receives the service data from the network device, the terminal device can perform HARQ-ACK feedback on the uplink, that is, the feedback information sent by the terminal device to the network device is ACK; if the terminal device fails to successfully receive (such as packet loss, decoding failure, etc.) the service data from the network device, the terminal device performs HARQ-NACK feedback on the uplink, that is, the feedback information sent by the terminal device to the network device is NACK. When the network device receives NACK feedback from the terminal device and the number of retransmissions has not reached the maximum number of retransmissions, the network device can then resend the last transmitted service data to the terminal device, and the terminal device can combine the service data received again with the service data that was not successfully received before to improve the receiving performance. In other words, the HARQ feedback mechanism can request retransmission when transmission fails, which can improve the reliability of data transmission.
HARQ反馈机制支持一次初传和至少一次重传。在一个业务数据的初传和后续的重传中，具体传输的是基于该业务数据经过数据信道编码之后的内容。例如，在LTE系统中，数据信道采用Turbo编码，同一个业务数据的不同编码后的内容可以由控制信息中的冗余版本(redundancy version，RV)序号指示。再比如，NR系统的数据信道可采用低密度奇偶校验码(low density parity check code，LDPC)编码，NR系统支持基于链路自适应(linkadaptation)的数据信道传输，即根据不同的信道状况选择不同的编码调制方式(包括但不限于码率和调制阶数)。由于编码特性的区别，基于LDPC码的数据信道链路自适应方式可以不同于基于Turbo码的方式。在NR系统中，同一个业务数据的不同编码后的内容的可以由控制信息中的冗余版本序号指示，也可以由其它指示信息指示，例如高层参数配置的冗余版本。应理解，初传和重传中发送的业务数据的编码后信息可以相同，也可以不同。The HARQ feedback mechanism supports one initial transmission and at least one retransmission. In the initial transmission and subsequent retransmission of a service data, the specific transmission is based on the content of the service data after data channel coding. For example, in the LTE system, the data channel adopts Turbo coding, and the different coded contents of the same service data can be indicated by the redundant version (RV) number in the control information. For another example, the data channel of the NR system can be encoded with low-density parity check code (LDPC), and the NR system supports data channel transmission based on link adaptation, that is, different coding and modulation methods (including but not limited to code rate and modulation order) are selected according to different channel conditions. Due to the difference in coding characteristics, the data channel link adaptation method based on LDPC code can be different from that based on Turbo code. In the NR system, the different coded contents of the same service data can be indicated by the redundant version number in the control information, or by other indication information, such as the redundant version configured by high-level parameters. It should be understood that the coded information of the service data sent in the initial transmission and retransmission can be the same or different.
需要说明的是，一个终端设备可以支持至少一个HARQ进程，在一个HARQ进程的某个业务数据被成功接收后，会清空用于存储该传输的存储器(例如，软存储器(softbuffer))，以准备使用该HARQ进程接收新的业务数据。在一个HARQ进程中，网络设备调度时可指示此次承载的业务数据为初传还是重传。示例性地，在LTE系统中，一个HARQ进程可以承载一个或者同时承载两个业务数据，当承载两个业务数据的时候，两个业务数据可以采用不同的编码调制方式。一次传输中，两个业务数据可以同为新传、同为重传或者一个是新传一个是重传。It should be noted that a terminal device can support at least one HARQ process. After a certain service data of a HARQ process is successfully received, the memory used to store the transmission (for example, soft buffer) will be cleared to prepare for using the HARQ process to receive new service data. In a HARQ process, the network device can indicate whether the service data carried this time is an initial transmission or a retransmission during scheduling. For example, in an LTE system, a HARQ process can carry one or two service data at the same time. When carrying two service data, the two service data can use different coding and modulation methods. In one transmission, two service data can be both new transmissions, both retransmissions, or one is a new transmission and the other is a retransmission.
图1中所示的网络设备和终端设备的形态和数量仅用于举例，并不构成对本申请的限定。The form and quantity of the network devices and terminal devices shown in FIG1 are for example only and do not constitute a limitation on the present application.
在介绍本申请的方法之前，基于图1所介绍的通信系统架构，对本申请所涉及的应用场景进行进一步的介绍说明，以便于理解本方案。需要说明的是，本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。Before introducing the method of the present application, based on the communication system architecture introduced in FIG. 1, the application scenarios involved in the present application are further introduced and explained to facilitate understanding of the present solution. It should be noted that the system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It is known to those skilled in the art that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.
如图2所示，为本申请提供的一种可适用的场景。在该可适用场景中，终端设备201可接收自网络设备202、网络设备203和网络设备204的业务数据。不同的网络设备发送的业务数据的业务类型、或者业务特性可能是不同的，同一网络设备也可以发送不同类型的业务数据。例如，网络设备202可向终端设备201传输业务类型为URLLC业务的业务数据，网络设备203可向终端设备201传输业务类型为IoT业务的业务数据，网络设备204可向终端设备201传输的业务类型为eMBB业务的业务数据。其中，URLLC业务主要具有超高可靠性(可靠性方面误块率(block error rate，BLER)至少达到99.999％)、低延时(端到端时延需要低于1ms)、传输数据量较少以及具有突发性，主要被应用于工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用。IoT业务占用带宽窄，功耗低，覆盖广，可重复发送，即自身就能保证一定的可靠性。eMBB业务主要具有传输数据量大、传输速率高的特性，主要被应用于超高清视频、增强现实(augmentedreality，AR)、虚拟现实(virtual reality，VR)等。在该场景下，若终端设备在接收到业务数据后，均向网络设备发送反馈信息时，会造成通信系统开销比较大的问题。As shown in Figure 2, an applicable scenario is provided for the present application. In this applicable scenario, the terminal device 201 can receive service data from the network device 202, the network device 203 and the network device 204. The service type or service characteristics of the service data sent by different network devices may be different, and the same network device can also send different types of service data. For example, the network device 202 can transmit service data of the service type URLLC service to the terminal device 201, the network device 203 can transmit service data of the service type IoT service to the terminal device 201, and the network device 204 can transmit service data of the service type eMBB service to the terminal device 201. Among them, the URLLC service mainly has ultra-high reliability (the block error rate (BLER) in terms of reliability is at least 99.999%), low latency (end-to-end latency needs to be less than 1ms), a small amount of transmitted data and burstiness, and is mainly used in wireless control in industrial manufacturing or production processes, motion control of unmanned vehicles and unmanned aircraft, and tactile interaction applications such as remote repair and remote surgery. IoT services occupy a narrow bandwidth, have low power consumption, wide coverage, and can be sent repeatedly, which means that they can guarantee a certain degree of reliability. eMBB services mainly have the characteristics of large data transmission volume and high transmission rate, and are mainly used in ultra-high-definition video, augmented reality (AR), virtual reality (VR), etc. In this scenario, if the terminal device sends feedback information to the network device after receiving the service data, it will cause a relatively large communication system overhead.
鉴于上述存在的技术问题，下面结合附图介绍本申请实施例提供的技术方案。In view of the above-mentioned technical problems, the technical solutions provided by the embodiments of the present application are described below in conjunction with the accompanying drawings.

The same is true for the second communication device, the second communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course other communication devices, such as a chip system. And there is no restriction on the implementation of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device is a network device, the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, or the first communication device is a terminal device, and the second communication device is a network device, etc.
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例。如图3所示，该方法包括以下步骤。For ease of introduction, the method is performed by a network device and a terminal device as an example. As shown in FIG3 , the method includes the following steps.
步骤301，网络设备为各分组配置指示信息。Step 301: The network device configures indication information for each group.
该步骤301为可选步骤。This step 301 is an optional step.
网络设备中的各分组可以是网络设备对多个业务分组得到的，也可以直接将已完成分组的各分组存储于网络设备中，本申请对此不做限定。Each group in the network device may be obtained by the network device grouping multiple services, or each completed group may be directly stored in the network device, and this application does not limit this.
网络设备对多个业务进行分组，可以有不同的方式，如下以三种示例性地实现方式进行详细介绍。There are different ways for a network device to group multiple services, which are described in detail below using three exemplary implementations.
实现方式一，网络设备可以根据业务特性对多个业务分组。也可以理解为，分到一个分组中的业务具有比较接近的业务特性。其中，业务特性包括但不限于：业务可靠性需求、业务覆盖能力、业务时延需求、业务数据量、业务移动性需求、或业务优先级。Implementation method 1: network equipment can group multiple services according to service characteristics. It can also be understood that services grouped into one group have relatively similar service characteristics. Among them, service characteristics include but are not limited to: service reliability requirements, service coverage capabilities, service delay requirements, service data volume, service mobility requirements, or service priority.
需要说明的是，网络设备根据业务特性对多个业务分组时，可以根据一个业务特性进行分组，也可以根据多个业务特性的组合进行分组，本申请对此不做限定。It should be noted that when a network device groups multiple services according to service characteristics, it can be grouped according to one service characteristic or according to a combination of multiple service characteristics, and this application does not limit this.
以下结合具体的示例对网络设备根据业务特性进行分组进行详细说明。The following describes in detail the grouping of network devices according to service characteristics with reference to specific examples.
示例一，基于业务覆盖能力。Example 1: Based on business coverage capabilities.
网络设备可根据业务特性中的业务覆盖能力对多个业务进行分组。例如，可以将覆盖能力较强的业务分到一个分组中，将覆盖能力较弱的业务分到另一分组种。示例性地，由于IoT业务和MTC业务的覆盖范围较广，即IoT业务和MTC业务具有覆盖能力较强，可以是将IoT业务和MTC(如eMTC、或者mMTC)业务分为一组，其余业务分为另一分组。再比如，也可以将覆盖能力分为高、中、低三个等级，一个等级对应一个分组。The network equipment can group multiple services according to the service coverage capability in the service characteristics. For example, services with strong coverage capabilities can be grouped into one group, and services with weak coverage capabilities can be grouped into another group. For example, since the coverage range of IoT services and MTC services is relatively wide, that is, IoT services and MTC services have strong coverage capabilities, IoT services and MTC services (such as eMTC or mMTC) services can be grouped into one group, and the remaining services can be grouped into another group. For another example, the coverage capability can also be divided into three levels: high, medium, and low, with one level corresponding to one group.
示例二，基于业务可靠性需求。Example 2: Based on business reliability requirements.
网络设备可根据业务特性中的业务可靠性需要对多个业务进行分组。例如，将可靠性需求较高的业务分为一组，将可靠性需要较松弛的业务分为另一种。示例性地，可以将可靠性需求大于99.999％的业务(如URLLC业务)分为一个组，将其余业务(如eMBB业务和其它业务)分到另一个分组中。The network device may group multiple services according to the service reliability requirements in the service characteristics. For example, services with higher reliability requirements may be grouped into one group, and services with looser reliability requirements may be grouped into another group. For example, services with a reliability requirement greater than 99.999% (such as URLLC services) may be grouped into one group, and the remaining services (such as eMBB services and other services) may be grouped into another group.
示例三，基于业务覆盖能力和业务可靠性需求。Example 3: Based on business coverage capability and business reliability requirements.
网络设备可根据业务特性中的业务覆盖能力和业务可靠性需求的组合对多个业务进行分组。例如，将业务覆盖能力较强且业务可靠性需求较高的业务分为一个分组，其余的业务分为另一个分组。再比如，将业务覆盖能力较强且业务可靠性需求较低的业务分为一组，其余的业务分为另一个分组。再比如，将业务覆盖能力较弱且业务可靠性需求较高的业务分为一组，其余的业务分为另一个分组。再比如，将业务覆盖能力较弱且业务可靠性需求较低的业务分为一组，其余的业务分为另一个分组。也就是说，根据多个业务的组合进行分组时，网络设备可根据实际需求自行决定将哪些业务特性进行组合，本申请对此不做限定。The network device can group multiple services according to the combination of service coverage capabilities and service reliability requirements in the service characteristics. For example, the services with strong service coverage capabilities and high service reliability requirements are grouped into one group, and the remaining services are grouped into another group. For another example, the services with strong service coverage capabilities and low service reliability requirements are grouped into one group, and the remaining services are grouped into another group. For another example, the services with weak service coverage capabilities and high service reliability requirements are grouped into one group, and the remaining services are grouped into another group. For another example, the services with weak service coverage capabilities and low service reliability requirements are grouped into one group, and the remaining services are grouped into another group. In other words, when grouping according to a combination of multiple services, the network device can decide which service characteristics to combine according to actual needs, and this application does not limit this.
实现方式二，网络设备可根据业务类型对多个业务分组。也可以理解为，分到一个分组中的业务具有相同的业务类型。In a second implementation mode, the network device can group multiple services according to service types. It can also be understood that the services grouped into one group have the same service type.
本申请中，业务类型包括但不限于：eMBB、URLLC、mMTC、V2X、和IoT。例如，可以将业务类型属于eMBB的业务分到一个分组中，将其余业务分到另一个组中；或者也可以业务类型属于V2X的业务分到一个分组中，将其余业务分到另一个组中；或者也可以将业务类型属于eMBB的业务分到一个分组中，业务类型属于V2X的业务分到另一个分组中，业务类型属于IoT的业务分到又一个分组中，将其余业务分到另一个组中；或者每个业务类型都对应一个分组，等等。In the present application, service types include but are not limited to: eMBB, URLLC, mMTC, V2X, and IoT. For example, services of eMBB type can be grouped into one group, and other services can be grouped into another group; or services of V2X type can be grouped into one group, and other services can be grouped into another group; or services of eMBB type can be grouped into one group, services of V2X type can be grouped into another group, services of IoT type can be grouped into another group, and other services can be grouped into another group; or each service type corresponds to one group, and so on.
实现方式三，网络设备根据业务类型和业务特性对多个业务分组。也可以理解为，分到一个组中的业务就有相同的业务类型、且具有相近的业务特性。In implementation mode 3, the network device groups multiple services according to service type and service characteristics. It can also be understood that services grouped into one group have the same service type and similar service characteristics.
示例性地，网络设备可将业务类型属于URLLC、且可靠性需求高于99.9999％的业务分到一个分组，将业务类型属于URLLC、且可靠性需求低于99.9999％的业务分到另一个分组。也可以理解为，属于相同业务类型的业务数据的业务特性之间可能会存在差异。网络设备根据业务类型和业务特性对多个业务进行分组，如此，可使得分到一个分组中的业务数据具有更相近的特性，使得各分组更精细，从而有助于提高反馈效率。Exemplarily, the network device may group services whose service type belongs to URLLC and whose reliability requirement is higher than 99.9999% into one group, and group services whose service type belongs to URLLC and whose reliability requirement is lower than 99.9999% into another group. It can also be understood that there may be differences between the service characteristics of service data belonging to the same service type. The network device groups multiple services according to service type and service characteristics, so that the service data grouped into one group can have more similar characteristics, making each group more refined, thereby helping to improve feedback efficiency.
实现方式四，网络设备也可将一个业务分到一个分组。即一个业务对应一个分组。如此，网络设备为各组配置指示信息，也就是说，网络设备为每个业务配置指示信息。如此，当一个业务有多个下行链路传输时，网络设备可为这5个下行链路配置一个指示信息，不需要针对每个链路都进行指示是否反馈，从而可更精确的提高发送反馈信息的效率。In implementation mode 4, the network device may also divide a service into a group. That is, one service corresponds to one group. In this way, the network device configures indication information for each group, that is, the network device configures indication information for each service. In this way, when a service has multiple downlink transmissions, the network device can configure one indication information for these five downlinks, and does not need to indicate whether to feedback for each link, thereby more accurately improving the efficiency of sending feedback information.
如上的四种分组方式只是举例，本申请并不限制如何分组。另外，网络设备选择如上的哪种实现方式来分组，可以由网络设备自行选择，例如网络设备可以随机选择，或者网络设备也可以根据某些因素选择，例如网络设备需要确定终端设备接收具有某一或某些业务特性的业务数据的情况，则网络设备可选择如上实现方式一来分组；或者，选择如上的哪种实现方式分组，也可以通过协议预定义。本申请对此不做限制。The above four grouping methods are just examples, and this application does not limit how to group. In addition, the network device can choose which of the above implementation methods to group by itself, for example, the network device can choose randomly, or the network device can also choose according to certain factors, for example, the network device needs to determine the situation where the terminal device receives service data with one or some service characteristics, then the network device can choose the above implementation method 1 to group; or, the selection of which of the above implementation methods to group can also be predefined by the protocol. This application does not limit this.
上述分组中包括第一标识，每个分组中的第一标识是不同的，也可以理解为，分组是以不同第一标识的方式体现的。其中，第一标识可以是业务标识，业务标识可以区分不同的业务。在一种可能的实现方式中，第一标识可以标识一个业务。在另一种可能的实现方式中，第一标识可以标识一组业务。如下为了便于方案的理解，以一个第一标识可以标识一个业务为例说明，即不同的业务可以通过不同的第一标识来区分。也就是说，一个第一标识可以标识出一个业务。示例性地，第一标识可以为TMGI，或者为G-RNTI，或者为MCCH，或者为SC-MCCH。一个TMGI是一个业务(例如广播多播业务)的特有标识，即可用TMGI来区分不同的业务；进一步，TMGI由PLMN ID和服务标识(service ID)两个域组成。一个业务在一个特定的小区配置有一个SC-MCCH或者在一个MBSFN区域配置有一个MCCH，也就是说，SC-MCCH或者MCCH也均可唯一的标识出一个业务。需要说明的是，TMGI、SC-MCCH或MCCH可用于在当终端设备处于空闲(IDLE)态时来标识业务。当终端设备处于无线资源控制(radio resourcecontrol，RRC)连接态时，即终端设备与网络设备建立连接后，网络设备可为每个业务分配一个业务标识，如G-RNTI，即终端设备处于RRC连接态时，传输的业务可用G-RNTI来标识；进一步，G-RNTI为MTCH或SC-MTCH加扰的扰码。The above grouping includes a first identifier, and the first identifier in each grouping is different. It can also be understood that the grouping is embodied in the form of different first identifiers. Among them, the first identifier can be a service identifier, and the service identifier can distinguish different services. In one possible implementation, the first identifier can identify a service. In another possible implementation, the first identifier can identify a group of services. In order to facilitate the understanding of the scheme, it is explained as follows that a first identifier can identify a service, that is, different services can be distinguished by different first identifiers. In other words, a first identifier can identify a service. Exemplarily, the first identifier can be TMGI, or G-RNTI, or MCCH, or SC-MCCH. A TMGI is a unique identifier of a service (such as a broadcast multicast service), that is, TMGI can be used to distinguish different services; further, TMGI consists of two fields: PLMN ID and service identifier (service ID). A service is configured with an SC-MCCH in a specific cell or an MCCH in an MBSFN area, that is, SC-MCCH or MCCH can also uniquely identify a service. It should be noted that TMGI, SC-MCCH or MCCH can be used to identify services when the terminal device is in an idle (IDLE) state. When the terminal device is in a radio resource control (RRC) connection state, that is, after the terminal device establishes a connection with the network device, the network device can assign a service identifier, such as G-RNTI, to each service, that is, when the terminal device is in an RRC connection state, the transmitted service can be identified by G-RNTI; further, G-RNTI is a scrambling code for MTCH or SC-MTCH scrambling.
示例性地，以组#1中包括三个第一标识(即第一标识1、第一标识2和第一标识3)、组#2中包括两个第一标识(即第一标识4和第一标识5)为例，若第一标识为TMGI，则组#1包括TMGI-1、TMGI-2、TMGI-3，组#2包括TMGI-4、TMGI-5。或者形成也可以是组#1＝{TMGI-1、TMGI-2、TMGI-3}，组#2＝{TMGI-4、TMGI-5}，该形式仅是示例性地，其它可能的形式也可以，例如，针对每个第一标识，指示出每个第一标识所属的组，本申请对此不做限定。同样地，若第一标识为G-RNTI，组#1＝{G-RNTI-1、G-RNTI-2、G-RNTI-3}，组#2＝{G-RNTI-4、G-RNTI-5}，若第一标识为SC-MCCH，组#1＝{SC-MCCH-1、SC-MCCH-2、SC-MCCH-3}，组#2＝{SC-MCCH-4、SC-MCCH-5}，若第一标识为MCCH，组#1＝{MCCH-1、MCCH-2、MCCH-3}，组#2＝{MCCH-4、MCCH-5}。Exemplarily, taking the example that group #1 includes three first identifiers (i.e., first identifier 1, first identifier 2, and first identifier 3) and group #2 includes two first identifiers (i.e., first identifier 4 and first identifier 5), if the first identifier is TMGI, group #1 includes TMGI-1, TMGI-2, TMGI-3, and group #2 includes TMGI-4 and TMGI-5. Alternatively, the formation may also be group #1 = {TMGI-1, TMGI-2, TMGI-3}, group #2 = {TMGI-4, TMGI-5}. This form is only exemplary, and other possible forms are also possible. For example, for each first identifier, the group to which each first identifier belongs is indicated, and this application does not limit this. Similarly, if the first identifier is G-RNTI, group #1 = {G-RNTI-1, G-RNTI-2, G-RNTI-3}, group #2 = {G-RNTI-4, G-RNTI-5}; if the first identifier is SC-MCCH, group #1 = {SC-MCCH-1, SC-MCCH-2, SC-MCCH-3}, group #2 = {SC-MCCH-4, SC-MCCH-5}; if the first identifier is MCCH, group #1 = {MCCH-1, MCCH-2, MCCH-3}, group #2 = {MCCH-4, MCCH-5}.
对于MBMS业务，当第一标识为TMGI时，由于TMGI为5～8个比特，即最小为5bit，可以标识出25＝32个业务；最大为8bit，可标识出28＝256个业务。也即是说，分组的数量与TMGI的比特相关，若TMGI的比特为5，则分组的最大数量为32个；若TMGI的比特为8，则分组的最大数量为256个。For MBMS services, when the first identifier is TMGI, since TMGI is 5 to 8 bits, the minimum is 5 bits, which can identify 25 = 32 services; the maximum is 8 bits, which can identify 28 = 256 services. In other words, the number of packets is related to the TMGI bits. If the TMGI bits are 5, the maximum number of packets is 32; if the TMGI bits are 8, the maximum number of packets is 256.
基于上述各分组，网络设备可为各分组配置指示信息。本申请中，指示信息可以包括但不限于以下示出的情形中的一种或多种的组合。Based on the above groups, the network device may configure indication information for each group. In the present application, the indication information may include but is not limited to one or more combinations of the following situations.
情形1，指示信息可以包括第一类参数，第一类参数用于表示反馈或不反馈。In case 1, the indication information may include a first type of parameter, and the first type of parameter is used to indicate feedback or no feedback.
在该情形1中，指示信息可以是反馈开关。具体可以包括两种状态：一种是开，另一种是关。示例性地，开可以用高层参数为ON表示，关用高层参数为OFF表示；或者开用高层参数置1表示，关用高层参数置0表示；或者也可以是其它可以区分出开和关的形式，本申请对开和关的具体表示形式不做限定。当一个分组#1对应的反馈开关的状态为开，则表示终端设备接收到属于该分组#1中的业务的数据后，需要向网络设备发送反馈信息。相应地，当一个分组#2对应的反馈开关的状态为关，则表示终端设备接收到属于该分组#2中的业务的数据后，不需要向网络设备发送反馈信息。或者指示信息也可以是一个指示字段，网络设备与终端设备可预先约定反馈和不反馈的具体形式。或者指示信息也可以是高层参数，如RRC信令。In this scenario 1, the indication information may be a feedback switch. Specifically, it may include two states: one is on and the other is off. Exemplarily, on may be represented by a high-level parameter of ON, and off may be represented by a high-level parameter of OFF; or on may be represented by a high-level parameter set to 1, and off may be represented by a high-level parameter set to 0; or it may be other forms that can distinguish between on and off, and the present application does not limit the specific representation of on and off. When the state of the feedback switch corresponding to a packet #1 is on, it means that after the terminal device receives the data belonging to the service in the packet #1, it needs to send feedback information to the network device. Correspondingly, when the state of the feedback switch corresponding to a packet #2 is off, it means that after the terminal device receives the data belonging to the service in the packet #2, it does not need to send feedback information to the network device. Alternatively, the indication information may also be an indication field, and the network device and the terminal device may pre-agree on the specific form of feedback and non-feedback. Alternatively, the indication information may also be a high-level parameter, such as RRC signaling.
网络设备为哪些分组配置哪些指示信息，如下给出了网络设备如何确定给哪些分组配置哪些指示信息的四种方式。The network device configures which indication information for which groups. Four methods are given below on how the network device determines which indication information to configure for which groups.
方式一：网络设备可根据各分组的业务特性为各分组配置指示信息。例如，对于业务可靠性需求较高的分组，可配置表示反馈的指示信息；对于业务可靠性需求较低的分组，可配置表示不反馈的指示信息。以指示信息为反馈开关为例，网络设备可为业务可靠性需求较高的分组配置的反馈开关的状态为开，对业务可靠性需求较低的分组配置的反馈开关的状态为关。或者，对于业务可靠性需求较高的分组，业务数据传输时会采用更加稳定的技术，一定程度上可保证传输的可靠性，因此也可配置表示不反馈的指示信息；对于业务可靠性需求较低的分组，误码率或误块率在90％左右，一次传输即可满足可靠性需求，因此，也可配置表示不反馈的指示信息。再比如，对于业务延时需求比较高(即要求时延较低)的分组，由于该分组中的业务对传输的时间预算有限，若终端设备对初传的第一数据接收失败之后向网络设备发送反馈信息，可能会超过时间预设，从而造成该反馈信息的传输为无效传输，因此，对于这种对业务延时需求较低的分组，网络设备通常会将第一数据自行传输多次。也就是说，网络设备可为该分组配置表示不反馈的指示信息；对业务延时需求比较低(即要求时延较高)的分组，网络设备可配置表示反馈的指示信息，从而可提高数据传输的可靠性。仍以指示信息为反馈开关为例，网络设备可为业务延时需求较低的分组配置的反馈开关的状态为开，对业务延时需求较高的分组配置的反馈开关的状态为关。再比如，对于业务可靠性需求较高且业务延时需求也较高的分组，可配置用于表示不反馈的指示信息，由于业务可靠性需求较高，即要求误码率或误块率达到99.999％或要求更高，则业务数据传输时会采用更加稳定的技术，一定程度上可保证传输的可靠性，这种情况可以不需要反馈，而且，由于对业务延时需求也较高，即要求延误延时低，为了防止重传的时间超出预算时间，造成重传为无效传输，也不需要向网络设备反馈。应理解，各个业务数据的业务延时需求、业务可靠性需求等可根据业务质量(quality of service，QoS)来确定。Method 1: The network device can configure indication information for each group according to the service characteristics of each group. For example, for groups with higher service reliability requirements, indication information indicating feedback can be configured; for groups with lower service reliability requirements, indication information indicating no feedback can be configured. Taking the indication information as a feedback switch as an example, the network device can configure the feedback switch state of the group with higher service reliability requirements to be on, and the feedback switch state of the group with lower service reliability requirements to be off. Alternatively, for groups with higher service reliability requirements, more stable technology will be used during service data transmission, which can guarantee the reliability of transmission to a certain extent, so indication information indicating no feedback can also be configured; for groups with lower service reliability requirements, the bit error rate or block error rate is about 90%, and one transmission can meet the reliability requirements, so indication information indicating no feedback can also be configured. For another example, for packets with relatively high service delay requirements (i.e., requiring relatively low delay), since the service in the packet has a limited time budget for transmission, if the terminal device sends feedback information to the network device after failing to receive the first data initially transmitted, it may exceed the preset time, thereby causing the transmission of the feedback information to be invalid. Therefore, for such packets with relatively low service delay requirements, the network device will usually transmit the first data multiple times by itself. In other words, the network device can configure indication information indicating no feedback for the packet; for packets with relatively low service delay requirements (i.e., requiring relatively high delay), the network device can configure indication information indicating feedback, thereby improving the reliability of data transmission. Still taking the indication information as a feedback switch as an example, the network device can configure the feedback switch state of the packet with relatively low service delay requirements as on, and the feedback switch state of the packet with relatively high service delay requirements as off. For another example, for packets with high service reliability requirements and high service delay requirements, indication information indicating no feedback can be configured. Since the service reliability requirements are high, that is, the bit error rate or block error rate is required to reach 99.999% or higher, more stable technology will be used for service data transmission, which can guarantee the reliability of transmission to a certain extent. In this case, feedback is not required. Moreover, since the service delay requirements are also high, that is, the delay is required to be low, in order to prevent the retransmission time from exceeding the budget time, resulting in invalid retransmission, feedback to the network device is not required. It should be understood that the service delay requirements and service reliability requirements of each service data can be determined according to the quality of service (QoS).
方式二：网络设备可根据各分组的业务类型为各分组配置指示信息。例如，网络设备可为业务类型属于URLLC的分组配置用于表示反馈的指示信息，为属于其他业务类型的分组配置用于表示不反馈的指示信息。Method 2: The network device may configure indication information for each group according to the service type of each group. For example, the network device may configure indication information for indicating feedback for groups whose service type belongs to URLLC, and configure indication information for indicating no feedback for groups belonging to other service types.
方式三：网络设备可根据当前终端设备与网络设备的通信状态(也可理解为是链路资源)来为各分组配置指示信息。例如，重传可能会导致传输拥塞。基于该通信状态，网络设备可为各分组配置用于表示不反馈的指示信息。特别是，各分组的业务是MBMS业务，由于MBMS是由网络设备向多个终端设备发送第一数据，若多个终端设备同时向网络设备发送反馈信息时，可能会导致链路资源不足，从而造成传输拥塞。Method 3: The network device can configure indication information for each group according to the current communication status between the terminal device and the network device (which can also be understood as link resources). For example, retransmission may cause transmission congestion. Based on the communication status, the network device can configure indication information for each group to indicate no feedback. In particular, the service of each group is MBMS service. Since MBMS is a first data sent by the network device to multiple terminal devices, if multiple terminal devices send feedback information to the network device at the same time, it may cause insufficient link resources, thereby causing transmission congestion.
方式四：网络设备可根据当前资源(如时频资源)占用情况来为各分组配置信息，例如当前资源比较紧缺，没有用于传输反馈信息的资源，网络设备可为各组均配置用于表示不反馈的指示信息。当这些分组是针对MBMS业务时，网络设备可关闭HARQ反馈机制，具体可通过高层信令通知终端设备关闭HARQ反馈机制，或者也可以为各个分组均配置用于表示不反馈的指示信息。Method 4: The network device can configure information for each group according to the current resource (such as time-frequency resource) occupancy. For example, if the current resources are relatively scarce and there are no resources for transmitting feedback information, the network device can configure indication information for each group to indicate no feedback. When these groups are for MBMS services, the network device can turn off the HARQ feedback mechanism, specifically by notifying the terminal device to turn off the HARQ feedback mechanism through high-level signaling, or can also configure indication information for each group to indicate no feedback.
如上的四种为各分组配置指示信息的方式只是举例，本申请并不限制为各分组配置指示信息。另外，网络设备选择如上的哪种方式来为各分组配置指示信息，可以由网络设备自行选择，例如网络设备可以随机选择，或者网络设备也可以根据某些因素选择，例如当前资源比较紧缺，则网络设备可选择如上方式四为各分组配置指示信息；或者，选择如上的哪种方式为各分组配置指示信息，也可以通过协议预定义。本申请对此不做限制。The above four methods of configuring indication information for each group are just examples, and the present application is not limited to configuring indication information for each group. In addition, the network device can choose which of the above methods to configure indication information for each group by itself, for example, the network device can choose randomly, or the network device can also choose according to certain factors, such as if the current resources are relatively scarce, then the network device can choose the above method 4 to configure indication information for each group; or, the selection of which of the above methods to configure indication information for each group can also be predefined by the protocol. The present application does not limit this.
情形2，指示信息可以包括第二类参数，第二类参数用于表示反馈判决参数的门限。其中，反馈判决参数可包括以下内容中任一项或任多项的组合：距离、RSRP、SINR。也就是，反馈判决参数可以是距离，或者是RSRP，或者是SINR，或者是距离和RSRP，或者是距离和SINR，或者是RSRP和SINR，或者是距离、RSRP和SINR。上述所列举的反馈判决参数仅是举例说明，本申请对反馈判决参数包括的具体内容不做限定。In case 2, the indication information may include a second type of parameter, and the second type of parameter is used to indicate the threshold of the feedback decision parameter. The feedback decision parameter may include any one or a combination of any two of the following: distance, RSRP, and SINR. That is, the feedback decision parameter may be distance, or RSRP, or SINR, or distance and RSRP, or distance and SINR, or RSRP and SINR, or distance, RSRP, and SINR. The feedback decision parameters listed above are only examples, and this application does not limit the specific contents of the feedback decision parameters.
上述距离可指终端设备与网络设备之间的地理距离(geographical distance)，地理距离表示网络设备与终端设备之间的绝对距离。可以理解的是，对于小区中心的终端设备，由于与网络设备之间的距离较近，可认为此时网络设备与终端设备之间的传输效果较好。对于小区边缘的终端设备，由于与网络设备之间的距离较远，可能无法获得较好的传输效果。也就是说，网络设备和终端设备之间的距离可以是小于某个值时，可以得到一个较好的传输效果。因此，距离为反馈判决参数时，距离的门限可为某个具体的距离值(如下可称为第一距离值)。或者，若终端设备与网络设备之间的距离太近，例如终端设备在网络设备的脚下，此时终端设备处于网络设备覆盖的盲区，即便终端设备向网络设备发送了未成功接收到数据的反馈信息，网络设备可能收不到该反馈信息；或者即便网络设备收到了终端设备的反馈信息，并再次进行了业务数据的重传，但由于终端设备处于网络设备覆盖的盲区，很大可能终端设备仍然不能成功接收到重传的业务数据。也就是说，如果网络设备和终端设备之间的距离较近时，也无法得到一个较好的传输效果。因此，距离为反馈判决参数时，距离的门限可也为某个具体的距离值(如下可称为第二距离值)。或者，由于终端设备与网络设备之间的距离太近或太远，均无法得到一个较好的传输效果，因此，网络设备和终端设备之间距离在一定范围时，终端设备向网络设备发送反馈信息才是有意义的。也可以理解为，距离为反馈判决参数时，距离的门限可为一个距离范围。需要说明的是，当距离作为反馈判决参数时，反馈判决参数的门限可以是某一个距离的值，也可以是一个距离范围。而且距离作为反馈判决参数时，不需要考虑当前信道条件如何。另外，距离的门限或某一距离的值均可以是经验值、历史数据统计值、或典型值等，该反馈判决参数的门限所对应某个距离的值或者对应的距离范围可使得终端设备与网络设备之间距离比较符合可正常通信的情况。The above distance may refer to the geographic distance between the terminal device and the network device, and the geographic distance indicates the absolute distance between the network device and the terminal device. It is understandable that for the terminal device in the center of the cell, since the distance between the terminal device and the network device is relatively close, it can be considered that the transmission effect between the network device and the terminal device is better at this time. For the terminal device at the edge of the cell, since the distance between the terminal device and the network device is relatively far, a better transmission effect may not be obtained. In other words, when the distance between the network device and the terminal device is less than a certain value, a better transmission effect can be obtained. Therefore, when the distance is a feedback decision parameter, the threshold of the distance may be a specific distance value (hereinafter referred to as the first distance value). Alternatively, if the distance between the terminal device and the network device is too close, for example, the terminal device is at the foot of the network device, the terminal device is in a blind spot covered by the network device at this time, even if the terminal device sends feedback information that the data is not successfully received to the network device, the network device may not receive the feedback information; or even if the network device receives the feedback information of the terminal device and retransmits the service data again, because the terminal device is in a blind spot covered by the network device, it is very likely that the terminal device still cannot successfully receive the retransmitted service data. That is to say, if the distance between the network device and the terminal device is close, a better transmission effect cannot be obtained. Therefore, when the distance is a feedback decision parameter, the threshold of the distance can also be a specific distance value (hereinafter referred to as the second distance value). Alternatively, since the distance between the terminal device and the network device is too close or too far, a better transmission effect cannot be obtained. Therefore, when the distance between the network device and the terminal device is within a certain range, it is meaningful for the terminal device to send feedback information to the network device. It can also be understood that when the distance is a feedback decision parameter, the threshold of the distance can be a distance range. It should be noted that when the distance is used as a feedback decision parameter, the threshold of the feedback decision parameter can be a certain distance value or a distance range. Moreover, when the distance is used as a feedback decision parameter, it is not necessary to consider the current channel conditions. In addition, the threshold of the distance or the value of a certain distance can be an empirical value, a historical data statistical value, or a typical value, etc. The value of a certain distance corresponding to the threshold of the feedback decision parameter or the corresponding distance range can make the distance between the terminal device and the network device more consistent with the situation where normal communication can be achieved.
上述RSRP为通信系统中可以代表无线信号强弱的相关参数，是指某个符号内承载参考信号的所有资源元素(resource element，RE)上接收到的信号功率的平均值。可以理解的是，RSRP的值较小时，说明无线信号覆盖比较差，例如，接收端的RSRP<＝-105dBm时，无线信号覆盖较差，业务基本无法起呼。当RSRP的值较小时，终端设备向网络设备发送反馈信息，网络设备可能收不到该反馈信息，或者即便网络设备收到了终端设备的反馈信息，并再次进行了业务数据的重传，由于无线信号覆盖较差，很大可能终端设备仍然不能成功接收到重传的业务数据。也就是说，RSRP的值较小时，终端设备向网络设备发送反馈信息，也无法获得较好的传输效果。RSRP的值较大(如>-75dBm)时，说明无线信号覆盖比较好，在该情况下，终端设备向网络设备发送反馈信息，可能会获得较好的传输效果。同样地，RSRP的门限可是经验值、历史数据统计值、或典型值等，该RSRP的门限内可使得终端设备与网络设备之间比较符合可正常通信的情况。The above RSRP is a relevant parameter that can represent the strength of the wireless signal in the communication system, and refers to the average value of the signal power received on all resource elements (RE) carrying the reference signal in a symbol. It can be understood that when the RSRP value is small, it means that the wireless signal coverage is relatively poor. For example, when the RSRP of the receiving end is <=-105dBm, the wireless signal coverage is poor and the service is basically unable to start a call. When the RSRP value is small, the terminal device sends feedback information to the network device, and the network device may not receive the feedback information, or even if the network device receives the feedback information of the terminal device and retransmits the service data again, due to the poor wireless signal coverage, it is very likely that the terminal device still cannot successfully receive the retransmitted service data. In other words, when the RSRP value is small, the terminal device sends feedback information to the network device, and cannot obtain a good transmission effect. When the RSRP value is large (such as >-75dBm), it means that the wireless signal coverage is relatively good. In this case, the terminal device sends feedback information to the network device, which may obtain a better transmission effect. Likewise, the RSRP threshold may be an empirical value, a historical data statistical value, or a typical value, etc. Within the RSRP threshold, the terminal device and the network device can relatively meet the condition of normal communication.
上述SINR也可称为信干噪比，指终端设备接收到的有用信号的强度与接收到的干扰信号(噪声和干扰)的强度的比值。可以理解的是，SINR的值较小，说明信道条件比较差，或者接收机噪声过高，或者接收机接收到的有用传输功率水平较低。在SINR的值较小的情况下，终端设备向网络设备发送反馈信息，网络设备可能收不到该反馈信息，或者即便网络设备收到了终端设备的反馈信息，并再次进行了业务数据的重传，由于有用信号的强度较小，终端设备即便接收到了重传的业务数据，很大可能终端设备不能成功译码重传的业务数据，因此也可能也无法获得较好的传输效果。在SINR的值较大(如>20dB)时，说明有用信号的强度比较好，在该情况下，终端设备向网络设备发送反馈信息，可能会获得较好的传输效果。同样地，SINR的门限可是经验值、历史数据统计值、或典型值等，该SINR的门限内可使得终端设备与网络设备之间比较符合可正常通信的情况。The above SINR can also be called signal-to-interference-noise ratio, which refers to the ratio of the strength of the useful signal received by the terminal device to the strength of the interference signal (noise and interference) received. It can be understood that a small SINR value indicates that the channel condition is relatively poor, or the receiver noise is too high, or the useful transmission power level received by the receiver is low. When the SINR value is small, the terminal device sends feedback information to the network device, and the network device may not receive the feedback information, or even if the network device receives the feedback information of the terminal device and retransmits the service data again, due to the small strength of the useful signal, even if the terminal device receives the retransmitted service data, it is very likely that the terminal device cannot successfully decode the retransmitted service data, so it may not be possible to obtain a better transmission effect. When the SINR value is large (such as> 20dB), it means that the strength of the useful signal is relatively good. In this case, the terminal device sends feedback information to the network device, which may obtain a better transmission effect. Similarly, the threshold of SINR can be an empirical value, a historical data statistical value, or a typical value, etc., and the threshold of the SINR can make the terminal device and the network device more in line with the situation of normal communication.
需要说明的是，不同的分组，配置的反馈判决参数的门限可能不同，也可能相同，本申请对此不做限定。另外，本申请中反馈判决参数的门限也可以是终端设备预配置的，或者是预定义的。或者也可以通过协议预定义，本申请对此也不做限定。此外，网络设备选择上述哪个反馈判决参数，可以由网络设备自行选择，例如网络设备可以随机选择；或者也可以是协议预定义网络设备选择上述哪种反馈判决参数。本申请对此不做限定。It should be noted that the thresholds of the configured feedback decision parameters may be different or the same for different groups, and this application does not limit this. In addition, the thresholds of the feedback decision parameters in this application may also be preconfigured or predefined by the terminal device. Or it may be predefined by the protocol, and this application does not limit this. In addition, the network device may select which of the above feedback decision parameters to select by itself, for example, the network device may select randomly; or the protocol may predefine which of the above feedback decision parameters to select by the network device. This application does not limit this.
情形3，指示信息可以包括第一类参数和第二类参数，第一类参数和第二类参数的详细介绍可分别参见上述情形1和情形2的介绍，此处不再赘述。In case 3, the indication information may include first-category parameters and second-category parameters. For detailed introduction of the first-category parameters and the second-category parameters, please refer to the introduction of the above-mentioned cases 1 and 2 respectively, which will not be repeated here.
情形4，指示信息可以包括预设条件。示例性地，网络设备与终端设备之间的当前实际距离落在某距离范围时反馈，或者当网络设备与终端设备之间的距离大于某距离的值时反馈；或者当网络设备与终端设备之间的距离小于某距离的值时反馈；或者当第一数据对应的当前SINR大于某SINR的值时反馈；或者当第一数据对应的当前RSRP大于某RSRP的值时反馈。In case 4, the indication information may include a preset condition. For example, feedback is provided when the current actual distance between the network device and the terminal device falls within a certain distance range, or when the distance between the network device and the terminal device is greater than a certain distance value; or when the distance between the network device and the terminal device is less than a certain distance value; or when the current SINR corresponding to the first data is greater than a certain SINR value; or when the current RSRP corresponding to the first data is greater than a certain RSRP value.

For example, the first type parameter indicates feedback, and the preset condition is feedback when the current actual distance between the network device and the terminal device falls within a certain distance range. For another example, the first type parameter indicates feedback, and the preset condition is feedback when the current SINR corresponding to the first data is greater than a certain SINR value; for another example, the first type parameter indicates feedback, and the preset condition is feedback when the current RSRP corresponding to the first data is greater than a certain RSRP value.
或者指示信息也可以包括第二类参数和预设条件。例如，当反馈判决参数为距离时，第二类参数为反馈判决距离的门限，则预设条件可为大于反馈判决距离的门限时反馈，或者小于反馈判决距离的门限时反馈，或者落入反馈判决距离的门限时反馈。再比如，当反馈判决参数为RSRP时，第二类参数为反馈判决RSRP的门限，则预设条件可为大于反馈判决RSRP的门限时反馈。再比如，当反馈判决参数为SINR时，第二类参数为反馈判决SINR的门限，则预设条件可为大于反馈判决SINR的门限时反馈。Or the indication information may also include a second type of parameter and a preset condition. For example, when the feedback decision parameter is distance, the second type of parameter is the threshold of the feedback decision distance, and the preset condition may be feedback when it is greater than the threshold of the feedback decision distance, or feedback when it is less than the threshold of the feedback decision distance, or feedback when it falls within the threshold of the feedback decision distance. For another example, when the feedback decision parameter is RSRP, the second type of parameter is the threshold of the feedback decision RSRP, and the preset condition may be feedback when it is greater than the threshold of the feedback decision RSRP. For another example, when the feedback decision parameter is SINR, the second type of parameter is the threshold of the feedback decision SINR, and the preset condition may be feedback when it is greater than the threshold of the feedback decision SINR.

This application does not impose any restrictions on this.
步骤302，网络设备向终端设备发送分组信息。相应地，终端设备接收来自网络设备的分组信息。Step 302: The network device sends packet information to the terminal device. Correspondingly, the terminal device receives the packet information from the network device.
此处，分组信息用于指示一个或多个分组包括的第一标识。其中，第一标识包括但不限于上述介绍的TMGI，G-RNTI，MCCH或SC-MCCH。具体的分组信息的指示形式可以是各分组中包括哪些第一标识，以第一标识为TMGI为例说明，分组信息的指示形式如组#1＝{TMGI-1、TMGI-2、TMGI-3}，组#2＝{TMGI-4、TMGI-5}；或者分组信息的指示形式也可以是指示出每个第一标识属于哪个分组，TMGI-1属于组#1，TMGI-2属于组#1，TMGI-3属于组#1，TMGI-4属于组#2、TMGI-5属于组#2，等等，本申请对分组信息的指示形式不做具体的限定。Here, the group information is used to indicate the first identifier included in one or more groups. The first identifier includes but is not limited to the TMGI, G-RNTI, MCCH or SC-MCCH introduced above. The specific indication form of the group information can be which first identifiers are included in each group. Taking the first identifier as TMGI as an example, the indication form of the group information is such as group #1 = {TMGI-1, TMGI-2, TMGI-3}, group #2 = {TMGI-4, TMGI-5}; or the indication form of the group information can also be to indicate which group each first identifier belongs to, TMGI-1 belongs to group #1, TMGI-2 belongs to group #1, TMGI-3 belongs to group #1, TMGI-4 belongs to group #2, TMGI-5 belongs to group #2, and so on. This application does not make specific limitations on the indication form of the group information.
进一步，分组信息还可包括各分组对应的指示信息。也就是说，一个分组对应一个指示信息。指示信息可以以显式的方式指示，或者也可以以隐式的方式指示。其中，指示信息的详细介绍可参见上述关于指示信息的介绍，此处不再赘述。Furthermore, the group information may also include indication information corresponding to each group. That is, one group corresponds to one indication information. The indication information may be indicated in an explicit manner or may be indicated in an implicit manner. For a detailed introduction to the indication information, please refer to the above introduction to the indication information, which will not be repeated here.
本申请中，分组信息指示各分组包括的第一标识、与各分组对应的指示信息可以通过一个信令发送至终端设备，例如，网络设备可通过RRC信令发送至终端设备，该RRC信令中包括分组信息指示各分组包括的第一标识、以及各分组对应的指示信息。或者，分组信息指示各分组包括的第一标识、与各分组对应的指示信息也可以通过两个信令发送至终端设备。例如，网络设备也可通过RRC信令发送至终端设备，一个RRC信令中包括分组信息指示各分组包括的第一标识，另一个RRC信令中包括各分组对应的指示信息，且这个两个RRC信令之间互不影响。进一步，通过两个信令发送至终端设备时，可以是分两次向终端设备发送，即一次向终端设备发送一条信令，也可以是一次将两条信令均发送至终端设备。可以理解的是，网络设备可以以多播(也称组播)的形式向终端设备发送分组信息，或者也可以以广播的形式向终端设备发送分组信息。In the present application, the first identifier included in the group information indicating each group and the indication information corresponding to each group can be sent to the terminal device through one signaling. For example, the network device can send it to the terminal device through RRC signaling, and the RRC signaling includes the first identifier included in the group information indicating each group, and the indication information corresponding to each group. Alternatively, the first identifier included in the group information indicating each group and the indication information corresponding to each group can also be sent to the terminal device through two signalings. For example, the network device can also send it to the terminal device through RRC signaling, one RRC signaling includes the first identifier included in each group indicating the group information, and the other RRC signaling includes the indication information corresponding to each group, and the two RRC signalings do not affect each other. Further, when sending to the terminal device through two signalings, it can be sent to the terminal device twice, that is, one signaling is sent to the terminal device once, or both signalings can be sent to the terminal device at one time. It can be understood that the network device can send the group information to the terminal device in the form of multicast (also called multicast), or it can also send the group information to the terminal device in the form of broadcast.
在一种可能的实现方式中，网络设备可通过高层信令向终端设备发送分组信息。例如，可以将分组信息携带于高层信令中。具体地，业务为多媒体广播多播业务(multimedia broadcast multicast service，MBMS)时，各分组信息可以携带于单小区点到多点(single cell point-to-multipoint，SC-PTM)配置信息中。在该实现方式中，高层信令也可称为配置信息。In a possible implementation, the network device may send packet information to the terminal device via high-layer signaling. For example, the packet information may be carried in the high-layer signaling. Specifically, when the service is a multimedia broadcast multicast service (MBMS), each packet information may be carried in single cell point-to-multipoint (SC-PTM) configuration information. In this implementation, the high-layer signaling may also be referred to as configuration information.
在另一种可能的实现方式中，网络设备也可通过系统消息向终端设备发送分组信息。例如，分组信息可以承载在系统消息中。其中，系统消息可以为信息块(systeminformation block x，SIBx)，如MBMS中的SIB13，或者MBMS中的SIB20。In another possible implementation, the network device may also send the grouping information to the terminal device via a system message. For example, the grouping information may be carried in a system message. The system message may be an information block (system information block x, SIBx), such as SIB13 in MBMS, or SIB20 in MBMS.
在又一种可能的实现方式中，网络设备还可通过下行控制信息(downlinkcontrol information，DCI)动态向终端设备通知各组对应的指示信息。In another possible implementation, the network device may also dynamically notify the terminal device of the indication information corresponding to each group through downlink control information (DCI).
步骤303，网络设备向终端设备发送第一数据。相应地，终端设备接收来自网络设备的第一数据。Step 303: The network device sends the first data to the terminal device. Correspondingly, the terminal device receives the first data from the network device.
此处，第一数据也可称为传输块、业务数据或者用户数据，第一数据可以承载于物理多播信道(physical multicast channel，PMCH)、或承载于下行共享物理信道(physicaldownlink shared channel，PDSCH)。需要说明的是，网络设备可以以广播的形式向多个终端设备发送第一数据，也可以以多播(组播)的形式向终端设备发送第一数据。Here, the first data may also be referred to as a transport block, service data or user data, and the first data may be carried on a physical multicast channel (PMCH) or a physical downlink shared channel (PDSCH). It should be noted that the network device may send the first data to multiple terminal devices in the form of broadcast, or may send the first data to the terminal devices in the form of multicast (groupcast).
步骤304，终端设备确定第一数据所属的第一分组，并根据第一分组对应的指示信息确定是否需要向网络设备发送反馈信息。一个实施例中，终端设备确定第一数据所属的第一分组，并根据第一分组对应的指示信息确定需要向网络设备发送反馈信息。Step 304: The terminal device determines the first group to which the first data belongs, and determines whether to send feedback information to the network device according to the indication information corresponding to the first group. In one embodiment, the terminal device determines the first group to which the first data belongs, and determines whether to send feedback information to the network device according to the indication information corresponding to the first group.
其中，第一分组为一个或多个分组中的一个。The first group is one of the one or more groups.
本申请中，反馈信息可以是HARQ反馈信息，HARQ反馈信息包括确认字符(acknowledgement，ACK)或否定确认字符(negative acknowledgment，NACK)。或者反馈信息也可以是信道状态信息(channel state information，CSI)，CSI包括信道质量信息(channel quality information，CQI)、预编码矩阵信息(precoding matrixinformation，PMI)和秩信息(rank information，RI)。或者，反馈信息也可以是HARQ反馈信息和CSI。需要说明的是，反馈信息是HARQ反馈信息还是CSI还是HARQ反馈信息和CSI，可以是网络设备指定并通知给终端设备的，也可以是网络设备和终端设备预先约定的，或者也可以是终端设备默认的，或者也可以通过协议预定义的，本申请对此不做限定。另外，网络设备通知给终端设备的反馈信息是什么，可以与分组信息一起发送至终端设备，也可以通过单独的信令发送至终端设备。In the present application, the feedback information may be HARQ feedback information, and the HARQ feedback information includes an acknowledgment character (ACK) or a negative acknowledgment character (NACK). Alternatively, the feedback information may also be channel state information (CSI), and the CSI includes channel quality information (CQI), precoding matrix information (PMI) and rank information (RI). Alternatively, the feedback information may also be HARQ feedback information and CSI. It should be noted that whether the feedback information is HARQ feedback information or CSI or HARQ feedback information and CSI may be specified by the network device and notified to the terminal device, or may be pre-agreed by the network device and the terminal device, or may be defaulted by the terminal device, or may be predefined by the protocol, and this application does not limit this. In addition, what the feedback information notified to the terminal device by the network device may be sent to the terminal device together with the packet information, or may be sent to the terminal device through a separate signaling.
本申请中结合MBMS，终端设备可通过如下方式确定第一数据所属的第一分组。In combination with MBMS in the present application, the terminal device may determine the first group to which the first data belongs in the following manner.
MBMS通常包括多媒体广播单频网(multimedia broadcast single frequencynetwork，MBSFN)传输和单小区点到多点(single cell point-to-multipoint，SC-PTM)传输两种传输方式。如下对则两种传输方式分别说明确定第一数据所属的第一分组的过程。MBMS generally includes two transmission modes: multimedia broadcast single frequency network (MBSFN) transmission and single cell point-to-multipoint (SC-PTM) transmission. The following describes the process of determining the first group to which the first data belongs for the two transmission modes respectively.
MBSFN传输方式，也称为单频网(SFN)传输方式。指在同一时间以相同频率在多个小区进行同步传输。该MBSFN传输方式可以节约频率资源，提高频谱利用率。同时这种多小区同频传输所带来的分集效果可以解决盲区覆盖等问题，可增强接收的可靠性以及提高覆盖率。针对该MBSFN传输方式，本申请中终端设备是指处于MBSFN区域的终端设备。其中，MBSFN区域是指通过协调实现了MBSFN传输的一组小区，整个MBSFN区域会被看作是一个MBSFN小区。也可以理解为，该组小区通过协调实现了MBSFN传输，使用相同得空口资源、且传输相同的MBMS。或者也可以理解为，预先配置若干个小区，组成一个MBSFN合并区，合并区内的多个网络设备使用相同的无线资源传输MBMS，即在相同的时刻将相同的业务数据发送给合并区内的所有终端设备。MBSFN transmission mode, also known as single frequency network (SFN) transmission mode. Refers to synchronous transmission in multiple cells at the same frequency at the same time. The MBSFN transmission mode can save frequency resources and improve spectrum utilization. At the same time, the diversity effect brought about by the multi-cell same-frequency transmission can solve problems such as blind area coverage, enhance the reliability of reception and improve coverage. For this MBSFN transmission mode, the terminal device in this application refers to a terminal device in the MBSFN area. Among them, the MBSFN area refers to a group of cells that achieve MBSFN transmission through coordination, and the entire MBSFN area will be regarded as an MBSFN cell. It can also be understood that this group of cells achieves MBSFN transmission through coordination, uses the same air interface resources, and transmits the same MBMS. Or it can also be understood that several cells are pre-configured to form an MBSFN merge area, and multiple network devices in the merge area use the same wireless resources to transmit MBMS, that is, the same service data is sent to all terminal devices in the merge area at the same time.
在该MBSFN传输方式中，可结合图4所示的信道之间的映射关系来确定第一数据所属的第一分组。由于MBMS在MAC层和物理层都有对应的信道来传输业务数据。MAC层中的逻辑信道主要包括多播控制信道(multicast control channel，MCCH)和多播传输信道(multicast traffic channel，MTCH)。其中，MCCH用于传输MBMS的控制信息，MTCH用于传输MBMS的业务数据，如第一数据。逻辑信道MCCH和MTCH复用到传输信道(multicast channel，MCH)上。例如，一个MTCH和一个MCCH可复用到一个MCH媒体接入控制的协议数据单元(MACprotocol data unit，MAC PDU)，或者仅一个MTCH承载于一个MCH MAC PDU中。MCH映射到PMCH上。当终端设备从物理信道接收到承载有第一数据的PMCH后，参考图4，根据PMCH与MCH的映射关系，可确定承载第一数据的PMCH所对应的MCH，之后根据MCH与MCCH之间的映射关系，可确定出第一数据对应的MCCH，由于一个MCCH对应一个MBSFN区域，即每个MBSFN区域都有一个MCCH，如此，可用一个MCCH标识一个业务，因此确定第一数据对应的MCCH所属的分组为第一分组。In this MBSFN transmission mode, the first group to which the first data belongs can be determined in combination with the mapping relationship between channels shown in Figure 4. Since MBMS has corresponding channels in the MAC layer and the physical layer to transmit service data. The logical channels in the MAC layer mainly include the multicast control channel (MCCH) and the multicast traffic channel (MTCH). Among them, MCCH is used to transmit the control information of MBMS, and MTCH is used to transmit the service data of MBMS, such as the first data. The logical channels MCCH and MTCH are multiplexed on the transport channel (multicast channel, MCH). For example, an MTCH and an MCCH can be multiplexed into an MCH media access control protocol data unit (MAC protocol data unit, MAC PDU), or only one MTCH is carried in an MCH MAC PDU. MCH is mapped to PMCH. When the terminal device receives the PMCH carrying the first data from the physical channel, referring to Figure 4, based on the mapping relationship between PMCH and MCH, the MCH corresponding to the PMCH carrying the first data can be determined, and then based on the mapping relationship between MCH and MCCH, the MCCH corresponding to the first data can be determined. Since one MCCH corresponds to one MBSFN area, that is, each MBSFN area has one MCCH, one MCCH can be used to identify one service, so the group to which the MCCH corresponding to the first data belongs is determined to be the first group.
SC-PTM传输方式，是指MBMS广播第一数据至特定的小区，这些特定的小区中必须有至少一个终端设备对广播的第一数据感兴趣。也就是说，在该SC-PTM传输中，终端设备是指对广播的第一数据感兴趣的终端设备。其中，MAC层中的逻辑信道主要包括SC-MCCH和单小区多播业务信道(single cell multicast traffic channel，SC-MTCH)。同样地，SC-MCCH用于传输MBMS的控制信息，SC-MTCH用于传输MBMS的业务数据，如第一数据。逻辑信道SC-MCCH和SC-MTCH映射到下行共享信道(downlink share channel，DL-SCH)上，DL-SCH映射到PDSCH上。The SC-PTM transmission mode refers to the MBMS broadcasting the first data to specific cells, and there must be at least one terminal device in these specific cells that is interested in the broadcasted first data. That is to say, in the SC-PTM transmission, the terminal device refers to the terminal device that is interested in the broadcasted first data. Among them, the logical channels in the MAC layer mainly include SC-MCCH and single cell multicast traffic channel (SC-MTCH). Similarly, SC-MCCH is used to transmit MBMS control information, and SC-MTCH is used to transmit MBMS service data, such as the first data. The logical channels SC-MCCH and SC-MTCH are mapped to the downlink shared channel (DL-SCH), and DL-SCH is mapped to PDSCH.
在该SC-PTM传输方式中，当终端设备接收到承载第一数据的PDSCH时，参考图5，根据PDSCH与DL-SCH的映射关系，确定承载第一数据的PDSCH所对应的DL-SCH，之后根据DL-SCH与SC-MCCH之间的映射关系，可确定出第一数据对应的SC-MCCH，又由于一个业务在一个特定小区中只能配置一个SC-MCCH，因此，可将第一数据对应的SC-MCCH所属的分组确定为第一分组。进一步，当终端设备处于RRC连接态时，网络设备会为第一数据配置一个G-RNTI，若第一标识为G-RNTI时，终端设备收到第一数据后，可确定出第一数据对应的G-RNTI，又由于对SC-MTCH加扰的扰码是G-RNTI，也就是说，一个G-RNTI可标识一个业务，因此，可将第一数据对应的G-RNTI所属的分组确定为第一分组。更进一步，若第一标识为TMGI，由于SC-MCCH承载有G-RNTI与TMGI的映射关系，从而可确定出第一数据对应的G-RNTI，再从该G-RNTI与TMGI的映射关系中确定出第一数据对应的G-RNTI所对应的TMGI，将第一数据对应的TMGI所在的分组确定为第一分组。In the SC-PTM transmission mode, when the terminal device receives the PDSCH carrying the first data, referring to FIG5, according to the mapping relationship between PDSCH and DL-SCH, the DL-SCH corresponding to the PDSCH carrying the first data is determined, and then according to the mapping relationship between DL-SCH and SC-MCCH, the SC-MCCH corresponding to the first data can be determined, and since only one SC-MCCH can be configured for a service in a specific cell, the group to which the SC-MCCH corresponding to the first data belongs can be determined as the first group. Further, when the terminal device is in an RRC connected state, the network device will configure a G-RNTI for the first data. If the first identifier is G-RNTI, after receiving the first data, the terminal device can determine the G-RNTI corresponding to the first data. Since the scrambling code for scrambling the SC-MTCH is G-RNTI, that is, one G-RNTI can identify one service, the group to which the G-RNTI corresponding to the first data belongs can be determined as the first group. Furthermore, if the first identifier is TMGI, since SC-MCCH carries the mapping relationship between G-RNTI and TMGI, the G-RNTI corresponding to the first data can be determined, and then the TMGI corresponding to the G-RNTI corresponding to the first data can be determined from the mapping relationship between G-RNTI and TMGI, and the group to which the TMGI corresponding to the first data belongs is determined as the first group.
基于上述确定出的第一分组，并结合上述指示信息的介绍，如下分别详细介绍终端设备根据第一分组对应的指示信息确定是否需要向网络设备发送反馈信息的过程。Based on the first group determined above, and in combination with the introduction of the indication information above, the process of the terminal device determining whether it needs to send feedback information to the network device according to the indication information corresponding to the first group is described in detail as follows.
基于上述情形1所介绍的指示信息，即指示信息为第一类参数，若终端设备确定第一分组对应的第一类参数表示反馈，则终端设备向网络设备发送反馈信息；若终端设备确定第一分组对应的第一类参数表示不反馈，则终端设备不向网络设备发送反馈信息。具体地，当第一类参数为反馈开关时，若终端设备确定第一分组对应的反馈开关的状态为开，则终端设备向网络设备发送反馈信息；若终端设备确定第一分组对应的反馈开关的状态为关，则终端设备不向网络设备发送反馈信息。Based on the indication information introduced in the above scenario 1, that is, the indication information is a first-class parameter, if the terminal device determines that the first-class parameter corresponding to the first group indicates feedback, the terminal device sends feedback information to the network device; if the terminal device determines that the first-class parameter corresponding to the first group indicates no feedback, the terminal device does not send feedback information to the network device. Specifically, when the first-class parameter is a feedback switch, if the terminal device determines that the state of the feedback switch corresponding to the first group is on, the terminal device sends feedback information to the network device; if the terminal device determines that the state of the feedback switch corresponding to the first group is off, the terminal device does not send feedback information to the network device.
基于上述情形2所介绍的指示信息，指示信息为第二类参数，终端设备在确定第一数据对应的反馈判决参数的值满足反馈判决参数的门限时，向网络设备发送反馈信息；或者，终端设备在确定第一数据对应的反馈判决参数的值不满足反馈判决参数的门限时，不向网络设备发送反馈信息。如下结合上述情形2中不同的反馈判决参数，分别说明。Based on the indication information introduced in the above scenario 2, the indication information is a second type of parameter. When the terminal device determines that the value of the feedback decision parameter corresponding to the first data meets the threshold of the feedback decision parameter, the terminal device sends feedback information to the network device; or, when the terminal device determines that the value of the feedback decision parameter corresponding to the first data does not meet the threshold of the feedback decision parameter, the terminal device does not send feedback information to the network device. The following is a description of the different feedback decision parameters in the above scenario 2.
示例A，反馈判决参数为距离，此处反馈判决参数的门限可称为距离的门限，为了便于方案的理解，将第一分组对应的距离的门限称为第一距离的门限。第一距离的门限可以是一个范围，也可以是某一距离值(如第一距离值或第二距离值)，结合上述关于距离作为反馈判决参数的介绍，此处以第一距离的门限为距离范围和某一距离值分别为例进行说明。Example A, the feedback decision parameter is distance, and the threshold of the feedback decision parameter here can be called the threshold of distance. In order to facilitate the understanding of the scheme, the threshold of the distance corresponding to the first group is called the threshold of the first distance. The threshold of the first distance can be a range or a certain distance value (such as the first distance value or the second distance value). Combined with the above introduction about distance as a feedback decision parameter, the threshold of the first distance is taken as a distance range and a certain distance value as examples for explanation.
在一种可能的实现方式中，第一距离的门限为距离范围。终端设备可根据网络设备的位置信息和自身的当前位置信息，确定出终端设备与网络设备之间的当前实际距离，该当前实际距离即为第一数据对应的反馈判决参数的值；若终端设备确定出的当前实际距离在该距离范围内，则终端设备向网络设备发送反馈信息；若终端设备确定出的当前实际距离不在该距离范围内，则终端设备不向网络设备发送反馈信息。例如，第一距离的门限为[100m-200m]，若终端设备确定出的当前实际距离为150m，150m在[100m-200m]范围内，因此终端设备向网络设备发送反馈信息；若终端设备确定当前实际距离为300m，300m不在[100m-200m]范围内，则终端设备不需要向网络设备发送反馈信息。In a possible implementation, the threshold of the first distance is a distance range. The terminal device can determine the current actual distance between the terminal device and the network device based on the location information of the network device and its own current location information. The current actual distance is the value of the feedback decision parameter corresponding to the first data; if the current actual distance determined by the terminal device is within the distance range, the terminal device sends feedback information to the network device; if the current actual distance determined by the terminal device is not within the distance range, the terminal device does not send feedback information to the network device. For example, the threshold of the first distance is [100m-200m]. If the current actual distance determined by the terminal device is 150m, 150m is within the range of [100m-200m], so the terminal device sends feedback information to the network device; if the terminal device determines that the current actual distance is 300m, 300m is not within the range of [100m-200m], then the terminal device does not need to send feedback information to the network device.
在另一种可能的实现方式中，第一距离的门限为第一距离值，且在当前实际距离小于该第一距离值时，终端设备向网络设备发送反馈信息。同样地，终端设备可根据网络设备的位置信息和自身的当前位置信息，确定出终端设备与网络设备之间的当前实际距离，若终端设备确定出的当前实际距离小于该第一距离值，则终端设备向网络设备发送反馈信息；若终端设备确定出的当前实际距离大于该第一距离值，则终端设备不需要向网络设备发送反馈信息。例如，第一距离值为200m，若终端设备确定出的当前实际距离为150m，150m小于200m，因此终端设备向网络设备发送反馈信息；若终端设备确定当前实际距离为300m，300m大于200m，则终端设备不需要向网络设备发送反馈信息。In another possible implementation, the threshold of the first distance is a first distance value, and when the current actual distance is less than the first distance value, the terminal device sends feedback information to the network device. Similarly, the terminal device can determine the current actual distance between the terminal device and the network device based on the location information of the network device and its own current location information. If the current actual distance determined by the terminal device is less than the first distance value, the terminal device sends feedback information to the network device; if the current actual distance determined by the terminal device is greater than the first distance value, the terminal device does not need to send feedback information to the network device. For example, if the first distance value is 200m, if the current actual distance determined by the terminal device is 150m, 150m is less than 200m, so the terminal device sends feedback information to the network device; if the terminal device determines that the current actual distance is 300m, 300m is greater than 200m, then the terminal device does not need to send feedback information to the network device.
在又一种可能的实现方式中，第一距离的门限为第二距离值，且在当前实际距离大于该第二距离值时，终端设备向网络设备发送反馈信息。同样地，终端设备可根据网络设备的位置信息和自身的当前位置信息，确定出终端设备与网络设备之间的当前实际距离，若终端设备确定出的当前实际距离大于该第二距离值，则终端设备向网络设备发送反馈信息；若终端设备确定出的当前实际距离小于该第二距离值，则终端设备不需要向网络设备发送反馈信息。例如，第二距离值为100m，若终端设备确定出的当前实际距离为150m，150m大于100m，因此终端设备向网络设备发送反馈信息；若终端设备确定当前实际距离为50m，50m小于200m，则终端设备不需要向网络设备发送反馈信息。In another possible implementation, the threshold of the first distance is a second distance value, and when the current actual distance is greater than the second distance value, the terminal device sends feedback information to the network device. Similarly, the terminal device can determine the current actual distance between the terminal device and the network device based on the location information of the network device and its own current location information. If the current actual distance determined by the terminal device is greater than the second distance value, the terminal device sends feedback information to the network device; if the current actual distance determined by the terminal device is less than the second distance value, the terminal device does not need to send feedback information to the network device. For example, if the second distance value is 100m, if the current actual distance determined by the terminal device is 150m, 150m is greater than 100m, so the terminal device sends feedback information to the network device; if the terminal device determines that the current actual distance is 50m, 50m is less than 200m, then the terminal device does not need to send feedback information to the network device.
需要说明的是，终端设备确定当前实际距离在距离范围内反馈，当前实际距离不在距离范围内不反馈，可以是终端设备默认的；或者也可以是网络设备通知终端设备的，例如网络设备预先通知给终端设备，或者随指示信息一起发送至终端设备；或者也可以是终端设备与网络设备预先约定的，或者也可以是协议预定义的，本申请对此不做限定。类似地，终端设备确定当前实际距离小于第一距离值反馈，或者大于第二距离反馈，可以是终端设备默认的；或者也可以是网络设备通知终端设备的，可以是预先通知的，也可以随指示信息一起发送至终端设备的；或者也可以是终端设备与网络设备预先约定的，或者也可以是协议预定义的，本申请对此不做限定。It should be noted that the terminal device determines that the current actual distance is within the distance range and feedback is given, and the current actual distance is not within the distance range and no feedback is given. This may be the default of the terminal device; or it may be notified by the network device to the terminal device, such as the network device notifies the terminal device in advance, or sends it to the terminal device together with the indication information; or it may be pre-agreed between the terminal device and the network device, or it may be pre-defined by the protocol, and this application does not limit this. Similarly, the terminal device determines that the current actual distance is less than the first distance value and feedback is given, or is greater than the second distance and feedback is given. This may be the default of the terminal device; or it may be notified by the network device to the terminal device, and it may be pre-notified, or it may be sent to the terminal device together with the indication information; or it may be pre-agreed between the terminal device and the network device, or it may be pre-defined by the protocol, and this application does not limit this.
另外，网络设备可以通过在第一数据中携带网络设备的位置信息；或者网络设备可预先将自身的位置信息发送至终端设备，例如网络设备在与终端设备建立连接后，网络设备将网络设备的位置信息通知给终端设备；或者也可以是终端设备在确定需要获知网络设备的位置信息时，向网络设备发送用于获取网络设备位置信息的请求，网络设备向终端设备发送响应，响应中包括网络设备的位置信息。另外，终端设备可通过自身内部的陀螺仪和传感器等确定出自身当前位置。In addition, the network device may carry the location information of the network device in the first data; or the network device may send its own location information to the terminal device in advance, for example, after the network device establishes a connection with the terminal device, the network device notifies the terminal device of the location information of the network device; or the terminal device may send a request for obtaining the location information of the network device to the network device when determining that the location information of the network device needs to be known, and the network device sends a response to the terminal device, and the response includes the location information of the network device. In addition, the terminal device can determine its current location through its internal gyroscope and sensors.
示例B，反馈判决参数为RSRP，此处反馈判决参数的门限可称为RSRP的门限，可将第一分组对应的RSRP的门限称为第一RSRP的门限。In example B, the feedback decision parameter is RSRP, where the threshold of the feedback decision parameter may be referred to as the RSRP threshold, and the RSRP threshold corresponding to the first group may be referred to as the first RSRP threshold.
在一种可能的实现方式中，终端设备在接收第一数据之前，可以先根据测量信号(也可称为参考信号)对当前信道进行测量，得到一个当前RSRP的值，该当前RSRP的值即为第一数据对应的反馈判决参数的值，当前RSRP的值可反映出当前信道的状态。端设备在接收到第一数据后，若终端设备确定当前RSRP的值小于第一RSRP的门限，则终端设备不向网络设备发送反馈信息；若终端设备确定当前RSRP的值大于或等于第一RSRP的门限，则终端设备向网络设备发送反馈信息。例如，第一RSRP的门限为-80dB，终端设备确定当前RSRP的值为-76dB，则终端设备向网络设备发送反馈信息；当终端设备确定当前RSRP的值为-106dB，则终端设备不需要向网络设备发送反馈信息。需要说明的是，终端设备确定当前RSRP的值小于第一RSRP的门限不反馈，大于第一RSRP的门限反馈，可以是终端设备默认的，也可以是网络设备预先通知终端设备的，或者也可以是协议预定义的，本申请对此不做限定。In a possible implementation, before receiving the first data, the terminal device may first measure the current channel according to the measurement signal (also referred to as the reference signal) to obtain a current RSRP value, which is the value of the feedback decision parameter corresponding to the first data. The current RSRP value can reflect the state of the current channel. After the terminal device receives the first data, if the terminal device determines that the current RSRP value is less than the threshold of the first RSRP, the terminal device does not send feedback information to the network device; if the terminal device determines that the current RSRP value is greater than or equal to the threshold of the first RSRP, the terminal device sends feedback information to the network device. For example, the threshold of the first RSRP is -80dB, and the terminal device determines that the current RSRP value is -76dB, then the terminal device sends feedback information to the network device; when the terminal device determines that the current RSRP value is -106dB, the terminal device does not need to send feedback information to the network device. It should be noted that the terminal device determines that if the current RSRP value is less than the threshold of the first RSRP, no feedback is given, but if it is greater than the threshold of the first RSRP, feedback is given. This can be the default of the terminal device, or it can be notified to the terminal device in advance by the network device, or it can be predefined by the protocol, and this application does not limit this.
示例C，反馈判决参数为SINR，此处反馈判决参数的门限可称为SINR的门限，可将第一分组对应的SINR的门限称为第一SINR的门限。In example C, the feedback decision parameter is SINR, where the threshold of the feedback decision parameter may be referred to as the SINR threshold, and the SINR threshold corresponding to the first group may be referred to as the first SINR threshold.
在一种可能的实现方式中，终端设备在接收到第一数据后，可先根据第一数据确定当前SINR的值，即终端设备将第一数据的功率与干扰噪声功率的比值确定为当前SINR的值，该当前SINR的值即为第一数据对应的反馈判决参数的值。若终端设备确定当前SINR的值小于第一SINR的门限，则终端设备不向网络设备发送反馈信息；若终端设备确定当前SINR的值大于或等于第一SINR的门限，则终端设备向网络设备发送反馈信息。例如，第一SINR的门限为0.8，当终端设备确定当前SINR的值为0.9，则终端设备向网络设备发送反馈信息。当终端设备确定当前SINR的值为0.5，则终端设备不需要向网络设备发送反馈信息。需要说明的是，终端设备确定当前SINR的值小于第一SINR的门限不反馈，大于第一SINR的门限反馈，可以是终端设备默认的，也可以是网络设备预先通知终端设备的，或者也可以是协议预定义的，本申请对此不做限定。In a possible implementation, after receiving the first data, the terminal device may first determine the value of the current SINR according to the first data, that is, the terminal device determines the ratio of the power of the first data to the interference noise power as the value of the current SINR, and the value of the current SINR is the value of the feedback decision parameter corresponding to the first data. If the terminal device determines that the value of the current SINR is less than the threshold of the first SINR, the terminal device does not send feedback information to the network device; if the terminal device determines that the value of the current SINR is greater than or equal to the threshold of the first SINR, the terminal device sends feedback information to the network device. For example, the threshold of the first SINR is 0.8, and when the terminal device determines that the value of the current SINR is 0.9, the terminal device sends feedback information to the network device. When the terminal device determines that the value of the current SINR is 0.5, the terminal device does not need to send feedback information to the network device. It should be noted that the terminal device determines that the current SINR value is less than the threshold of the first SINR and does not feedback, and the threshold feedback greater than the first SINR can be the default of the terminal device, or it can be notified to the terminal device in advance by the network device, or it can be predefined by the protocol, and this application does not limit this.
示例D，反馈判决参数为距离和RSRP，此处反馈判决参数的门限为距离的门限和RSRP的门限的组合，同样地，可将第一分组对应的反馈判决参数的门限称为第一距离的门限和第一RSRP的门限的组合。终端设备在接收到第一数据后，若确定终端设备与网络设备之间的当前实际距离满足第一距离的门限、且当前RSRP参数的值满足第一RSRP的门限时，向网络设备发送反馈信息；否则，不向网络设备发送反馈信息，具体的判断过程可参见上述示例A和示例B，此处不再赘述。Example D, the feedback decision parameters are distance and RSRP, where the threshold of the feedback decision parameter is a combination of the distance threshold and the RSRP threshold. Similarly, the threshold of the feedback decision parameter corresponding to the first group can be called a combination of the first distance threshold and the first RSRP threshold. After receiving the first data, if the terminal device determines that the current actual distance between the terminal device and the network device meets the first distance threshold and the current RSRP parameter value meets the first RSRP threshold, it sends feedback information to the network device; otherwise, it does not send feedback information to the network device. The specific judgment process can be found in the above examples A and B, which will not be repeated here.
需要说明的是，终端设备可以先确定当前实际距离是否满足第一距离的门限，当当前实际距离满足第一距离门限时，再确定当前RSRP的值是否满足第一RSRP的门限。或者在确定当前RSRP的值满足第一RSRP的门限时，再确定当前实际距离是否满足第一距离门限，或者，同时确定终端设备当前RSRP的值是否满足第一RSRP的门限、以及当前实际距离是否满足第一距离的门限。若反馈判决参数的门限为两个或两个以上的组合时，终端设备可以随机选择先进行哪个的判断，也可以预先规定判断的顺序，或者也可以是网络设备向终端设备指示判断顺序，或者也可以是终端设备依据一定的因素确定判断的顺序，本申请对此不做限定。It should be noted that the terminal device may first determine whether the current actual distance meets the threshold of the first distance, and when the current actual distance meets the first distance threshold, determine whether the current RSRP value meets the first RSRP threshold. Or when it is determined that the current RSRP value meets the first RSRP threshold, determine whether the current actual distance meets the first distance threshold, or simultaneously determine whether the current RSRP value of the terminal device meets the first RSRP threshold and whether the current actual distance meets the first distance threshold. If the threshold of the feedback decision parameter is a combination of two or more, the terminal device may randomly select which judgment to make first, or may predefine the order of judgment, or the network device may indicate the order of judgment to the terminal device, or the terminal device may determine the order of judgment based on certain factors, and this application does not limit this.
本申请中，反馈判决参数也可以为距离和SINR的组合，相应地，反馈判决参数的门限为距离的门限与SINR的门限的组合；或者反馈判决参数可以为RSRP和SINR的组合，相应地，反馈判决参数的门限为RSRP的门限与SINR的门限的组合；或者反馈判决参数可以为距离、RSRP和SINR的组合，相应地，反馈判决参数的门限为距离门限、RSRP的门限与SINR的门限的组合。另外，针对各种组合，终端设备判决的顺序可参见上述示例D的说明，此处不再赘述。In the present application, the feedback decision parameter may also be a combination of distance and SINR, and accordingly, the threshold of the feedback decision parameter is a combination of the distance threshold and the SINR threshold; or the feedback decision parameter may be a combination of RSRP and SINR, and accordingly, the threshold of the feedback decision parameter is a combination of the RSRP threshold and the SINR threshold; or the feedback decision parameter may be a combination of distance, RSRP and SINR, and accordingly, the threshold of the feedback decision parameter is a combination of the distance threshold, the RSRP threshold and the SINR threshold. In addition, for various combinations, the order of the terminal device's decision can refer to the description of the above example D, which will not be repeated here.
基于上述情形3所介绍的指示信息，即指示信息为第一类参数和第二类参数。终端设备确定第一数据所属的第一分组对应的第一类参数表示反馈、且第一数据对应的反馈判决参数的值满足反馈判决参数的门限时，向网络设备发送反馈信息；或者终端设备在确定第一分组对应的第一类参数表示反馈、且第一数据对应的反馈判决参数的值不满足反馈判决参数的门限时，则不需要向网络设备发送反馈信息；或者终端设备确定第一分组对应的第一类参数表示不反馈、且第一数据对应的反馈判决参数的值满足反馈判决参数的门限时，则不需要向网络设备发送反馈信息；或者终端设备确定第一分组对应的第一类参数表示不反馈、且第一数据对应的反馈判决参数的值不满足反馈判决参数的门限时，则不需要向网络设备发送反馈信息；或者终端设备在确定出第一分组对应的第一类反馈参数表示不反馈，可以不再确定第二类参数的值。其中，第一分组对应的第一类参数表示反馈的确定过程可参见上述基于情形1的确定过程，反馈判决参数的值满足反馈判决参数的门限可参见上述基于情形2(如示例A、示例B和示例C)的介绍，此处不再赘述。需要说明的是，终端设备可以先确定第一类参数，在确定第一类参数表示反馈的情况下再确定第二类参数；或者也可以先确定第二类参数，在确定第二类参数用于表示反馈的情况下，再确定第一类参数，本申请对先确定第一类参数还是先确定第二类参数不做限定。Based on the indication information introduced in the above scenario 3, that is, the indication information is the first type parameter and the second type parameter. When the terminal device determines that the first type parameter corresponding to the first group to which the first data belongs indicates feedback, and the value of the feedback decision parameter corresponding to the first data meets the threshold of the feedback decision parameter, the feedback information is sent to the network device; or when the terminal device determines that the first type parameter corresponding to the first group indicates feedback, and the value of the feedback decision parameter corresponding to the first data does not meet the threshold of the feedback decision parameter, it is not necessary to send feedback information to the network device; or when the terminal device determines that the first type parameter corresponding to the first group indicates no feedback, and the value of the feedback decision parameter corresponding to the first data meets the threshold of the feedback decision parameter, it is not necessary to send feedback information to the network device; or when the terminal device determines that the first type parameter corresponding to the first group indicates no feedback, and the value of the feedback decision parameter corresponding to the first data does not meet the threshold of the feedback decision parameter, it is not necessary to send feedback information to the network device; or when the terminal device determines that the first type of feedback parameter corresponding to the first group indicates no feedback, and the value of the feedback decision parameter corresponding to the first data does not meet the threshold of the feedback decision parameter, it is not necessary to send feedback information to the network device; or when the terminal device determines that the first type of feedback parameter corresponding to the first group indicates no feedback, it may no longer determine the value of the second type parameter. Among them, the determination process of the first type of parameter corresponding to the first group indicating feedback can refer to the determination process based on scenario 1 above, and the value of the feedback decision parameter satisfies the threshold of the feedback decision parameter can refer to the introduction based on scenario 2 (such as example A, example B and example C) above, which will not be repeated here. It should be noted that the terminal device can first determine the first type of parameter, and then determine the second type of parameter when it is determined that the first type of parameter indicates feedback; or it can first determine the second type of parameter, and then determine the first type of parameter when it is determined that the second type of parameter is used to indicate feedback. This application does not limit whether the first type of parameter or the second type of parameter is determined first.
基于上述情形4所介绍的指示信息，即指示信息为预设条件。若预设条件为网络设备与终端设备之间的当前实际距离落在某距离范围时反馈，则终端设备在接收到第一数据后，可根据网络设备的位置信息和自身的当前位置信息，确定出终端设备与网络设备之间的当前实际距离，若终端设备确定出的当前实际距离在该预设条件中的距离范围内，则终端设备向网络设备发送反馈信息；否则，终端设备不需向网络设备发送反馈信息。Based on the indication information introduced in the above scenario 4, that is, the indication information is a preset condition. If the preset condition is to provide feedback when the current actual distance between the network device and the terminal device falls within a certain distance range, then after receiving the first data, the terminal device can determine the current actual distance between the terminal device and the network device based on the location information of the network device and its own current location information, and if the current actual distance determined by the terminal device is within the distance range in the preset condition, the terminal device sends feedback information to the network device; otherwise, the terminal device does not need to send feedback information to the network device.
或者预设条件为第一数据对应的当前SINR大于某SINR的值时反馈，则终端设备在接收到第一数据后，可确定第一数据对应的当前SINR，若终端设备确定出的第一数据对应的当前SINR大于预设条件中某SINR的值，则终端设备向网络设备发送反馈信息；否则，终端设备不需向网络设备发送反馈信息。Or the preset condition is that feedback is given when the current SINR corresponding to the first data is greater than a certain SINR value. After receiving the first data, the terminal device can determine the current SINR corresponding to the first data. If the current SINR corresponding to the first data determined by the terminal device is greater than a certain SINR value in the preset condition, the terminal device sends feedback information to the network device; otherwise, the terminal device does not need to send feedback information to the network device.
或者预设条件为第一数据对应的当前RSRP大于某RSRP的值时反馈，则终端设备在接收到第一数据后，可确定第一数据对应的当前RSRP，若终端设备确定出的第一数据对应的当前RSRP大于预设条件中某RSRP的值，则终端设备向网络设备发送反馈信息；否则，终端设备不需向网络设备发送反馈信息。Or the preset condition is that feedback is provided when the current RSRP corresponding to the first data is greater than a certain RSRP value. Then, after receiving the first data, the terminal device can determine the current RSRP corresponding to the first data. If the current RSRP corresponding to the first data determined by the terminal device is greater than a certain RSRP value in the preset condition, the terminal device sends feedback information to the network device; otherwise, the terminal device does not need to send feedback information to the network device.
基于上述情形5，指示信息包括第一类参数和预设条件。以预设条件为网络设备与终端设备之间的当前实际距离落在某距离范围时反馈为例，终端设备在确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，还需要进一步确定终端设备与网络设备之间的当前实际距离是否落入距离范围内，若落入，则反馈；若未落入，则不需要反馈。以预设条件为第一数据对应的当前SINR大于某SINR的值时反馈为例，终端设备在确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，还需要进一步确定接收到的第一数据对应的当前SINR是否大于预设条件中的某SINR的值，若大于，则反馈；若不大于，则不需要反馈。以预设条件为第一数据对应的当前RSRP大于某RSRP的值时反馈为例，终端设备在确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，还需要进一步确定接收到的第一数据对应的当前RSRP是否大于预设条件中的某RSRP的值，若大于，则反馈；若不大于，则不需要反馈。Based on the above scenario 5, the indication information includes the first type of parameters and preset conditions. Taking the preset condition that the current actual distance between the network device and the terminal device falls within a certain distance range as an example, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and it is also necessary to further determine whether the current actual distance between the terminal device and the network device falls within the distance range. If it does, feedback is given; if it does not, no feedback is required. Taking the preset condition that the current SINR corresponding to the first data is greater than a certain SINR value as an example, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and it is also necessary to further determine whether the current SINR corresponding to the received first data is greater than a certain SINR value in the preset condition. If it is, feedback is given; if it is not, no feedback is required. Taking the preset condition that the current RSRP corresponding to the first data is greater than a certain RSRP value as an example, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and it is also necessary to further determine whether the current RSRP corresponding to the received first data is greater than a certain RSRP value in the preset condition. If it is, feedback is given; if it is not, no feedback is required.
基于上述情形6的指示信息，若指示信息为第一类参数表示反馈，第二类参数表示反馈判决距离的门限，预设条件为大于反馈判决参数距离的门限时反馈，则终端设备在接收到第一数据后，终端设备确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，并确定网络设备与终端设备之间的当前实际距离大于反馈判决参数距离的门限时，终端设备向网络设备发送反馈信息。其中，终端设备确定当前的实际距离可参见上述示例A的介绍，此处不再赘述。或者，指示信息为第一参数表示反馈，第二类参数表示反馈判决SINR的门限，预设条件为大于反馈判决SINR的门限时反馈，则终端设备在接收到第一数据后，终端设备在确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，并确定第一数据对应的当前SINR大于反馈判决SINR的门限时，则终端设备向网络设备发送反馈信息。或者，指示信息为第一类参数表示反馈，第二参数表示反馈判决RSRP的门限，预设条件可为大于反馈判决RSRP的门限时反馈，则终端设备在接收到第一数据后，终端设备在确定接收到的第一数据所述的第一分组对应的第一类参数表示反馈，并确定第一数据对应的当前RSRP大于反馈判决RSRP的门限时，则终端设备向网络设备发送反馈信息。Based on the indication information of the above scenario 6, if the indication information is a first type of parameter indicating feedback, and a second type of parameter indicating a threshold of the feedback decision distance, and the preset condition is feedback when it is greater than the threshold of the feedback decision parameter distance, then after the terminal device receives the first data, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and determines that the current actual distance between the network device and the terminal device is greater than the threshold of the feedback decision parameter distance, the terminal device sends feedback information to the network device. Among them, the terminal device determines the current actual distance as described in the above example A, which will not be repeated here. Alternatively, the indication information is a first parameter indicating feedback, and the second type of parameter indicates a threshold of the feedback decision SINR, and the preset condition is feedback when it is greater than the threshold of the feedback decision SINR, then after the terminal device receives the first data, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and determines that the current SINR corresponding to the first data is greater than the threshold of the feedback decision SINR, then the terminal device sends feedback information to the network device. Alternatively, the indication information is a first type of parameter indicating feedback, and a second parameter indicating a threshold for feedback decision RSRP, and the preset condition may be feedback when the value is greater than the threshold for feedback decision RSRP. Then, after receiving the first data, the terminal device determines that the first type of parameter corresponding to the first group described in the received first data indicates feedback, and determines that the current RSRP corresponding to the first data is greater than the threshold for feedback decision RSRP, then the terminal device sends feedback information to the network device.
为了进一步降低系统的反馈开销，终端设备可以在确定需要向网络设备发送反馈信息，且确定反馈信息满足反馈条件时，向网络设备发送反馈信息，反馈条件为未正确解析第一数据。也就是说，终端设备可以在确定需要向网络设备发送反馈信息、且确定反馈信息为NACK时，再向网络设备发送反馈信息；若终端设备确定需要向网络设备发送反馈信息、但反馈信息为ACK，不需要向网络设备发送反馈信息。如此，网络设备并不需要得知每个第一数据的传输情况，例如当网络设备广播第一数据时，是要将第一数据发送给很多个终端设备，此时，网络设备只需要知道具有特定业务特征或属于特定类型的业务中哪些第一数据未被终端设备正确解析，以便网络设备重传。对于没有反馈的，网络设备可以认为第一数据已被终端设备正确接收。这样可以减少终端设备发给网络设备的ACK/NACK控制信息数量，可在保证有效反馈的前提下，有助于降低系统的开销和损耗，从而实现更高效的反馈。应理解，未正确解析第一数据包括但不限于对第一数据解调译码失败。In order to further reduce the feedback overhead of the system, the terminal device can send feedback information to the network device when it is determined that feedback information needs to be sent to the network device and the feedback information meets the feedback condition, and the feedback condition is that the first data is not correctly parsed. That is to say, the terminal device can send feedback information to the network device when it is determined that feedback information needs to be sent to the network device and the feedback information is NACK; if the terminal device determines that feedback information needs to be sent to the network device, but the feedback information is ACK, it is not necessary to send feedback information to the network device. In this way, the network device does not need to know the transmission status of each first data. For example, when the network device broadcasts the first data, the first data is to be sent to many terminal devices. At this time, the network device only needs to know which first data in the service with specific service characteristics or belonging to a specific type is not correctly parsed by the terminal device, so that the network device can retransmit. For those without feedback, the network device can assume that the first data has been correctly received by the terminal device. In this way, the number of ACK/NACK control information sent by the terminal device to the network device can be reduced, which can help reduce the system overhead and loss under the premise of ensuring effective feedback, thereby achieving more efficient feedback. It should be understood that the incorrect parsing of the first data includes but is not limited to the failure of demodulation and decoding of the first data.
本申请中，网络设备可为各分组配置一个公共的资源，终端设备在确定需要向网络设备发送反馈信息时，可在该分组对应的组公共资源上发送反馈信息，其中，组公共资源是指一个小区中的终端设备可分为多个组，每个组都有对应的组公共资源，组内的终端设备可使用该组的组公共资源，其它组中的终端设备不能使用。或者，网络设备也可为各终端设备在公共资源上被分配了用于发送反馈信息的特定资源，其中，公共资源是指同一个小区内所有终端设备都可以用的资源。In this application, the network device can configure a common resource for each group. When the terminal device determines that it needs to send feedback information to the network device, it can send feedback information on the group common resource corresponding to the group, wherein the group common resource means that the terminal devices in a cell can be divided into multiple groups, each group has a corresponding group common resource, the terminal devices in the group can use the group common resource of the group, and the terminal devices in other groups cannot use it. Alternatively, the network device can also allocate specific resources for each terminal device on the common resource for sending feedback information, wherein the common resource refers to the resource that can be used by all terminal devices in the same cell.
本申请中，当网络设备接收到来自终端设备的反馈信息后，若确定接收到的是ACK，则说明终端设备成功接收到了第一数据，网络设备可以继续后面的业务数据的传输；若确定接收到的是NACK，则说明终端设备未成功接收到第一数据，网络设备可以重传该第一数据。In the present application, when the network device receives feedback information from the terminal device, if it is determined that what is received is ACK, it means that the terminal device has successfully received the first data, and the network device can continue to transmit subsequent business data; if it is determined that what is received is NACK, it means that the terminal device has not successfully received the first data, and the network device can retransmit the first data.
从上述步骤301至步骤303可以看出，通过将多个业务分组，并为各分组配置指示信息，可实现有些分组需要向网络设备发送反馈信息，即开启反馈机制，有些业务不需要向网络设备发送反馈信息，即未开启(或者已关闭)反馈机制。对于终端设备接收到属于未开启反馈机制的分组中的第一数据后，不论是否正确解析该第一数据，都不需要向网络设备发送任何反馈信息，如此，有助于减少通信系统的反馈开销(除有用的数据外的控制信息均被称为开销)，而且，也可降低系统的复杂度。进一步，可通过对业务传输可靠性需求高的业务设置为一个分组，并为该分组配置开启反馈机制，如可，可保证该分组中业务数据的传输高可靠性需求。It can be seen from the above steps 301 to 303 that by grouping multiple services and configuring indication information for each group, it can be achieved that some groups need to send feedback information to the network device, that is, the feedback mechanism is turned on, and some services do not need to send feedback information to the network device, that is, the feedback mechanism is not turned on (or has been closed). After the terminal device receives the first data in the group that does not have a feedback mechanism turned on, no matter whether the first data is correctly parsed, it is not necessary to send any feedback information to the network device. This helps to reduce the feedback overhead of the communication system (all control information except useful data is called overhead), and can also reduce the complexity of the system. Furthermore, by setting the service with high service transmission reliability requirements as a group, and configuring the feedback mechanism to turn on for the group, if possible, the high reliability requirements for the transmission of service data in the group can be guaranteed.
