技术领域technical field
本发明涉及通信技术领域，特别是涉及一种信息传输方法和装置。The present invention relates to the field of communication technology, in particular to an information transmission method and device.
背景技术Background technique
下一代移动通信系统要求大容量和高质量的数据传输。多输入多输出(MIMO,multiple input multiple output)技术被认为是可实现未来高速数据传输的关键技术之一，在第三代(3G)及第四代(4G)的移动通信系统中有着广阔的应用前景。传统的集中式MIMO系统的多根发射天线均集中于基站(BS,basestation)端。与集中式MIMO不同，分布式MIMO系统的多根发射天线分布于不同的地理位置，其各对收发链路之间更加独立，具有大容量、低功耗、更好的覆盖、对人体的低电磁损害等优势，被认为是未来无线通信系统的备选方案之一。在分布式MIMO的情况下，为了提高边缘用户设备的信号可靠性以及为了提高边缘小区的吞吐量，可以考虑采用多点分集或者多点多流的传输方法。Next-generation mobile communication systems require large-capacity and high-quality data transmission. Multiple input multiple output (MIMO, multiple input multiple output) technology is considered to be one of the key technologies that can realize high-speed data transmission in the future. It has a broad application in the third generation (3G) and fourth generation (4G) mobile communication systems. Application prospects. Multiple transmitting antennas of a traditional centralized MIMO system are all concentrated at the base station (BS, basestation) end. Different from the centralized MIMO system, the multiple transmitting antennas of the distributed MIMO system are distributed in different geographical locations, and each pair of transmitting and receiving links is more independent, with large capacity, low power consumption, better coverage, and low impact on the human body. Advantages such as electromagnetic damage are considered to be one of the options for future wireless communication systems. In the case of distributed MIMO, in order to improve the signal reliability of the edge user equipment and the throughput of the edge cell, a multi-point diversity or multi-point multi-stream transmission method may be considered.
协同多点传输(CoMP，coordinated multipoint transmission)被认为是一种解决小区间干扰问题并提升边缘用户设备吞吐量的有效方法。CoMP技术中多个相邻小区可以联合处理或协调边缘用户设备来避免干扰并提升边缘用户吞吐量。下行CoMP的场景主要包括联合传输(JT，joint transmission)、协同调度和波束成型(CS/CB，coordinatedscheduling and beamforming)和动态点选择/关闭(DPS/DPB，dynamic point selection/dynamic point blanking)，其中JT分为相干JT和非相干JT，上行CoMP的场景包括联合接收(JR，Joint reception)、CS和DPS/DPB。Coordinated multipoint transmission (CoMP, coordinated multipoint transmission) is considered to be an effective method to solve the inter-cell interference problem and improve the throughput of edge user equipment. In the CoMP technology, multiple adjacent cells can jointly process or coordinate edge user equipment to avoid interference and improve edge user throughput. Downlink CoMP scenarios mainly include joint transmission (JT, joint transmission), coordinated scheduling and beamforming (CS/CB, coordinated scheduling and beamforming) and dynamic point selection/closing (DPS/DPB, dynamic point selection/dynamic point blanking), where JT is divided into coherent JT and non-coherent JT. Uplink CoMP scenarios include joint reception (JR, Joint reception), CS, and DPS/DPB.
在上述CoMP的一些场景，如JT或DPS中，因为不同基站，如图1a中的第一基站和第二基站，到达用户设备(UE，userequipment)，如UE1的传输时延不同，如图1a中T1为第一基站到达UE1的传输时延，T2为第二基站到达UE1的传输时延，T1和T2的不同会导致传输性能下降。In some scenarios of the above CoMP, such as JT or DPS, because different base stations, such as the first base station and the second base station in Figure 1a, reach the user equipment (UE, user equipment), such as UE1, with different transmission delays, as shown in Figure 1a Among them, T1 is the transmission delay from the first base station to UE1, and T2 is the transmission delay from the second base station to UE1. The difference between T1 and T2 will lead to a decrease in transmission performance.

本发明实施例既可以应用于时分双工(time division duplex，TDD)的场景，也可以适用于频分双工(frequency division duplex，FDD)的场景。The embodiment of the present invention can be applied to a time division duplex (time division duplex, TDD) scenario, and can also be applied to a frequency division duplex (frequency division duplex, FDD) scenario.
图2示出了本发明实施例的一种可能的系统网络示意图。如图2所示，至少一个用户设备UE10与无线接入网(radio access network,RAN)进行通信。所述RAN包括至少一个基站20(base station,BS)，为清楚起见，图中只示出一个基站和一个UE。所述RAN与核心网络(core network,CN)相连。可选的，所述CN可以耦合到一个或者更多的外部网络(external network)，例如英特网，公共交换电话网(public switched telephonenetwork，PSTN)等。Fig. 2 shows a schematic diagram of a possible system network of the embodiment of the present invention. As shown in FIG. 2, at least one user equipment UE10 communicates with a radio access network (radio access network, RAN). The RAN includes at least one base station 20 (base station, BS). For clarity, only one base station and one UE are shown in the figure. The RAN is connected to a core network (core network, CN). Optionally, the CN may be coupled to one or more external networks, such as the Internet, a public switched telephone network (public switched telephone network, PSTN) and the like.
本发明实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或TRP，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。The embodiments of the present invention can be applied not only in traditional typical networks, but also in future UE-centric (UE-centric) networks. The UE-centric network introduces a non-cell network architecture, that is, a large number of small stations are deployed in a specific area to form a Hyper cell, and each small station is a transmission point of the Hyper cell ( Transmission Point, TP) or TRP, and connected with a centralized controller (controller). When the UE moves in the Hyper cell, the network side device selects a new sub-cluster (sub-cluster) for the UE to serve it from time to time, thereby avoiding real cell handover and realizing the continuity of the UE service. Wherein, the network side device includes a wireless network device.
如图1a和图1b中所示的，不同基站到达UE的传输时延不同，会导致传输性能的下降。As shown in FIG. 1 a and FIG. 1 b , different base stations have different transmission delays to reach the UE, which will lead to degradation of transmission performance.
有鉴于此，本发明实施例提供一种信息传输方法，使得不同基站到达UE的传输时延差可测，从而使得基站可以从UE接收传输时延差，并根据传输时延差进行相应的相位调整，使得与同一个UE进行传输的基站的传输时延差在可接受范围内，如小于预设的门限值，进而提高传输性能。In view of this, the embodiment of the present invention provides an information transmission method, so that the transmission delay difference between different base stations to the UE can be measured, so that the base station can receive the transmission delay difference from the UE, and perform corresponding phase adjustment according to the transmission delay difference The adjustment is made so that the transmission delay difference between the base stations transmitting with the same UE is within an acceptable range, for example, less than a preset threshold value, thereby improving transmission performance.
本发明实施例中不同基站可以为具有不同的标识的基站，也可以为具有相同的标识的被部署在不同地理位置的基站。由于在基站被部署前，基站并不会知道其是否会涉及本发明实施例所应用的场景，因而，基站，或基带芯片，都应在部署前就支持本发明实施例所提供的方法。可以理解的是，前述具有不同标识的基站可以为基站标识，也可以为小区标识或者而其他标识。也就是说，本发明实施例中的不同无线网络设备，如基站，主要指的是会导致到达UE的传输时延不同的无线网络设备，通常为射频单元被部署在不同地理位置的无线网络设备。In this embodiment of the present invention, different base stations may be base stations with different identifiers, or base stations with the same identifier deployed in different geographic locations. Before the base station is deployed, the base station does not know whether it will be involved in the application scenario of the embodiment of the present invention, therefore, the base station or the baseband chip should support the method provided by the embodiment of the present invention before deployment. It can be understood that the aforementioned base stations with different identities may be base station identities, cell identities, or other identities. That is to say, different wireless network devices in the embodiments of the present invention, such as base stations, mainly refer to wireless network devices that cause different transmission delays to reach the UE, and are usually wireless network devices where radio frequency units are deployed in different geographical locations .
本发明实施例中部分场景以无线通信网络中4G网络的场景为例进行说明，应当指出的是，本发明实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。Some scenarios in the embodiments of the present invention are described by taking the scenario of a 4G network in a wireless communication network as an example. It should be noted that the solutions in the embodiments of the present invention can also be applied to other wireless communication networks, and the corresponding names can also be used in other The name of the corresponding function in the wireless communication network is replaced.
需指出的是，本发明实施例中的方法或装置可以应用于无线网络设备和用户设备之间，也可以应用于无线网络设备和无线网络设备(如宏基站和微基站)之间，还可以应用于用户设备和用户设备(如D2D场景)之间，在本发明所有实施例中，以无线网络设备和UE之间的通信为例进行描述。It should be noted that the method or device in the embodiment of the present invention can be applied between a wireless network device and a user equipment, or between a wireless network device and a wireless network device (such as a macro base station and a micro base station), and can also be Applied between a user equipment and a user equipment (such as a D2D scene), in all embodiments of the present invention, the communication between a wireless network device and a UE is taken as an example for description.

示例的，UE从第二无线网络设备接收第一参考信号。Exemplarily, the UE receives the first reference signal from the second wireless network device.
可选的，第一参考信号可以为协议预定义的用于传输时延测量的参考信号，这样，UE就无需根据配置信息来确定哪个信号用于传输时延的测量。Optionally, the first reference signal may be a reference signal predefined by the protocol for transmission delay measurement, so that the UE does not need to determine which signal is used for transmission delay measurement according to configuration information.
可选的，UE根据配置信息来确定第一参考信号为用于传输时延的测量的参考信号。Optionally, the UE determines, according to configuration information, that the first reference signal is a reference signal used for transmission delay measurement.
示例的，如S00所示，UE从第一无线网络设备接收所述配置信息。Exemplarily, as shown in S00, the UE receives the configuration information from the first wireless network device.
可选的，第一无线网络设备可以与第二无线网络设备为同一无线网络设备，也可以为不同的无线网络设备。比如，第一无线网络设备为UE的服务小区所归属的无线网络设备，而第二无线网络设备为UE的非服务小区所归属的无线网络设备。可选的，第一无线网络设备和第二无线网络设备可以共用基带单元，而具有不同的射频单元，比如可以被部署在不同地理位置上的射频单元。第一无线网络设备和第二无线网络设备也可以既不共用基带单元，又不共用射频单元。Optionally, the first wireless network device and the second wireless network device may be the same wireless network device, or may be different wireless network devices.

示例的，UE可以从第一无线网络设备接收同步信号或参考信号(UE和第一无线网络设备达到同步状态)，并通过UE的接收机接收第一参考信号。由于第一参考信号的序列为UE所已知的，通过UE的接收机的调整，UE可以获得正确接收第一参考信号所需的调整，进而获知第一参考信号的传输时延。Exemplarily, the UE may receive a synchronization signal or a reference signal from the first wireless network device (the UE and the first wireless network device have reached a synchronization state), and receive the first reference signal through a receiver of the UE. Since the sequence of the first reference signal is known to the UE, through the adjustment of the receiver of the UE, the UE can obtain the adjustment needed to correctly receive the first reference signal, and then know the transmission delay of the first reference signal.

The correspondence between the information of the first transmission delay and the first transmission delay may be pre-stored on the side of the UE and the wireless network device, thereby reducing the overhead required for transmission of the transmission delay.

In this way, the first wireless network device and/or the second wireless network device can adjust the phase according to the information of the first transmission delay. In this way, when both the second wireless network device and the first wireless network device transmit data (including signaling) to the UE, the transmission of data received by the UE from the first wireless network device and from the second wireless network device The delay can be smaller than the preset threshold value, thereby improving the transmission performance. Optionally, when the UE does not send the information of the first transmission delay to the second wireless network device, the first wireless network device may send the information of the first transmission delay to the second wireless network device, so that The second wireless network device adjusts the phase according to the information about the first transmission delay.

Exemplarily, the second reference signal is received from the third wireless network device. The UE obtains the second transmission delay according to the second reference signal.
可选的，第二参考信号可以为协议预定义的用于传输时延测量的参考信号，这样，UE就无需根据配置信息来确定哪个信号用于传输时延的测量。Optionally, the second reference signal may be a reference signal predefined by the protocol for transmission delay measurement, so that the UE does not need to determine which signal is used for transmission delay measurement according to configuration information.
可选的，UE根据配置信息来确定第二参考信号为用于传输时延的测量的参考信号。Optionally, the UE determines, according to configuration information, that the second reference signal is the reference signal used for transmission delay measurement.
示例的，如S00所示，UE从第一无线网络设备接收所述配置信息。Exemplarily, as shown in S00, the UE receives the configuration information from the first wireless network device.
S2与S1类似，可以参考S1中的描述，在此不予赘述。S2 is similar to S1, and reference may be made to the description in S1, which will not be repeated here.
可以理解的是，第二参考信号和第一参考信号可以是相同种类的参考信号，比如，都是用于信道状态信息获取的参考信号，如信道状态信息参考信号CSI-RS，也可以是不同种类的参考信号，比如，一个是用于信道状态信息获取的参考信号，而另一个是用于解调的参考信号，如解调参考信号DMRS。It can be understood that the second reference signal and the first reference signal may be the same type of reference signal, for example, both are reference signals used for channel state information acquisition, such as the channel state information reference signal CSI-RS, or they may be different Types of reference signals, for example, one is a reference signal for acquiring channel state information, and the other is a reference signal for demodulation, such as a demodulation reference signal DMRS.
可选的，第三无线网络设备与第一无线网络设备或第二无线网络设备可以共用基带单元，而具有不同的射频单元，比如可以被部署在不同地理位置上的射频单元。第三无线网络设备与第一无线网络设备或第二无线网络设备也可以既不共用基带单元，又不共用射频单元。Optionally, the third wireless network device may share a baseband unit with the first wireless network device or the second wireless network device, but have different radio frequency units, for example, radio frequency units that may be deployed in different geographic locations.

For example, information about the second transmission delay is sent to the first wireless network device and/or the third wireless network device. It can be understood that the information of the second transmission delay may be the index of the transmission delay corresponding to the second transmission delay, or may be the corresponding quantized information, which will not be repeated here. The information about the second transmission delay and the corresponding relationship between the second transmission delay may be pre-stored on the side of the UE and the wireless network device, thereby reducing the overhead required for transmission delay transmission.
这样，通过第一传输时延和/或第二传输时延的获得及第一传输时延的信息和/或第二传输时延的信息的传输，可以使得第二无线网络设备和/或第三无线网络设备可以进行相应的相位调整，进而使得第一，第二和第三无线网络设备中的任意两个或三个在与UE进行通信的过程中，传输时延差可以小于一门限值，达到接近理论上的同时到达UE的效果。In this way, by obtaining the first transmission delay and/or the second transmission delay and transmitting the information of the first transmission delay and/or the information of the second transmission delay, the second wireless network device and/or the second wireless network device can The three wireless network devices can perform corresponding phase adjustments, so that any two or three of the first, second and third wireless network devices can communicate with the UE, and the transmission delay difference can be less than a threshold The value is close to the theoretical effect of reaching the UE at the same time.
在另一种可能的实施方式中，S3，UE根据第一传输时延和第二传输时延获得传输时延差。In another possible implementation manner, S3, the UE obtains a transmission delay difference according to the first transmission delay and the second transmission delay.
可选的，S31，UE发送所述传输时延差的信息。Optionally, S31. The UE sends information about the transmission delay difference.
示例的，UE可以向第一，第二和第三无线网络设备中的至少一个发送传输时延差的信息，从而使得第一，第二和第三无线网络设备中的至少一个可以根据传输时延差的信息进行相位的调整，进而使得第一，第二和第三无线网络设备中的任意两个或三个在与UE进行通信的过程中，传输时延差可以小于一门限值，达到接近理论上的同时到达UE的效果。Exemplarily, the UE may send transmission delay difference information to at least one of the first, second and third wireless network devices, so that at least one of the first, second and third wireless network devices can The information of the delay difference is used to adjust the phase, so that any two or three of the first, second and third wireless network devices can communicate with the UE, and the transmission delay difference can be less than a threshold value, The effect of reaching the UE at the same time close to the theory is achieved.
可以理解的是，传输时延差的信息可以为传输时延差的索引，也可以为传输时延差经量化后的信息，在此不予赘述。传输时延差的信息与传输时延差之间的对应关系可以预先存储于UE和无线网络设备侧，从而减少传输时延传输所需的开销。It can be understood that the information of the transmission delay difference may be an index of the transmission delay difference, or may be quantized information of the transmission delay difference, which will not be repeated here. The information of the transmission delay difference and the corresponding relationship between the transmission delay difference may be pre-stored on the side of the UE and the wireless network device, thereby reducing the overhead required for transmission delay transmission.
可选的，UE可以根据S00中所包括的配置信息获知第一参考信号和/或第二参考信号用于用于传输时延和/或传输时延差的获得。Optionally, according to the configuration information included in S00, the UE may learn that the first reference signal and/or the second reference signal are used for obtaining the transmission delay and/or the transmission delay difference.
可以理解的是，图3中的步骤之间的前后并不表示各步骤的先后关系，比如，S1和S2可以同时进行，也可以不同时进行，S00可以在其他步骤之前，也可以夹杂在其他步骤之间进行，S00可以包括在一次配置中，也可以包括在多次配置中，这多次配置的时间可以根据实际系统需要进行，在本发明实施例中不予限定。It can be understood that the sequence of the steps in Figure 3 does not represent the sequence of the steps. For example, S1 and S2 can be performed at the same time or not at the same time, and S00 can be performed before other steps or mixed with other steps. Between the steps, S00 may be included in one configuration, or may be included in multiple configurations, and the time of these multiple configurations may be performed according to actual system needs, which is not limited in the embodiment of the present invention.
示例的，配置信息中可以包括第一指示信息和/或第二指示信息，其中，第一指示信息用于指示第一参考信号用于传输时延的测量(如UE基于第一参考信号获得传输时延差和/或传输时延)，第二指示信息用于指示第二参考信号用于传输时延的测量(如UE基于第二参考信号获得传输时延差和/或传输时延)。For example, the configuration information may include first indication information and/or second indication information, where the first indication information is used to indicate that the first reference signal is used for transmission delay measurement (for example, the UE obtains transmission delay based on the first reference signal) Delay difference and/or transmission delay), the second indication information is used to indicate that the second reference signal is used for transmission delay measurement (for example, UE obtains transmission delay difference and/or transmission delay based on the second reference signal).
为了描述的简练，以下实施例中的S00中的配置信息在描述中有时仅以传输时延差的获得和/或反馈为例进行描述，可以理解的是，相应的配置信息也可以用于传输时延的获得和/或反馈，即将传输时延差替换为第一或第二传输时延即可，在此不予赘述。For brevity of description, the configuration information in S00 in the following embodiments is sometimes only described by taking the acquisition and/or feedback of the transmission delay difference as an example. It can be understood that the corresponding configuration information can also be used for transmission The acquisition and/or feedback of the delay is just to replace the transmission delay difference with the first or second transmission delay, which will not be repeated here.
可选的，第一指示信息用于指示第一参考信号用于传输时延的测量包括：Optionally, the first indication information used to indicate that the first reference signal is used for transmission delay measurement includes:
所述第一指示信息包括在信道状态信息测量集合域，信道状态信息报告集合域，或者，参考信号资源域中的至少一项中，所述第一指示信息用于指示所述信道状态信息测量集合域，信道状态信息报告集合域，或者，参考信号资源域中的至少一项中所包括的参考信号资源标识中的一个所对应的参考信号为第一参考信号,所述第一参考信号用于传输时延的测量。The first indication information is included in at least one of the channel state information measurement set field, the channel state information report set field, or the reference signal resource field, and the first indication information is used to indicate that the channel state information measurement The set field, the channel state information report set field, or the reference signal corresponding to one of the reference signal resource identifiers included in at least one of the reference signal resource fields is the first reference signal, and the first reference signal uses For the measurement of transmission delay.
示例的，可以在信道状态信息测量集合域(CSI measurement setting)中配置时延测量信息域(Time-delay-Config)，即第一指示信息。Exemplarily, the delay measurement information field (Time-delay-Config), that is, the first indication information, may be configured in the channel state information measurement set field (CSI measurement setting).
比如，可以在时延测量信息域中包括资源集合标识(resource setting ID)，CSI测量集合ID(CSI measurement setting ID)，资源ID(resource ID)中的一种或多种。其中，CSI measurement setting ID是指用于进行CSI测量的集合的配置信息对应的标识，resource setting ID是指资源集合的配置信息对应的标识，资源集合可以包括用于信道测量的资源和/或用于干扰测量的资源，资源ID为资源的配置信息对应的标识。示例的，UE可以被配置N≥1个CSI上报集合(reporting setting)，M≥1个资源集合和1个CSImeasurement setting，其中，CSI measurement setting可以包括L≥1条链路。其中，每个CSI reporting setting至少包括：上报的CSI参数，CSI类型(I或II)(如果上报的话)，码本配置(包括码本子集约束)，时域行为，用于CQI(信道质量信息，channel qualityindicator)和PMI(预编码矩阵信息，precoding matrix indicator)的频率间隔，测量约束配置等。每个资源集合中可以包括：S≥1个CSI-RS资源集合的配置(其中，不同集合对应于从所有配置给UE的CSI-RS资源池中的不同选择)。每个集合中的Ks≥1个CSI-RS资源的配置至少包括：资源元素(resource element，RE)的映射，端口数，时域行为等。CSImeasurement setting中的L条链路中的每条都具有：CSI reporting setting指示，resource setting指示，需测量的质量信息(如是信道还是干扰)，其中，一个CSIreporting集合可以和一个或多个resource setting相关联，多个CSI reporting集合可以和同一个resource setting相关联。For example, one or more of a resource set identifier (resource setting ID), a CSI measurement set ID (CSI measurement setting ID), and a resource ID (resource ID) may be included in the delay measurement information field. Wherein, the CSI measurement setting ID refers to the identifier corresponding to the configuration information of the set used for CSI measurement, and the resource setting ID refers to the identifier corresponding to the configuration information of the resource set, and the resource set may include resources used for channel measurement and/or For the resource of the interference measurement, the resource ID is an identifier corresponding to the configuration information of the resource. For example, the UE may be configured with N≥1 CSI reporting sets (reporting setting), M≥1 resource sets and 1 CSI measurement setting, where the CSI measurement setting may include L≥1 links. Among them, each CSI reporting setting includes at least: reported CSI parameters, CSI type (I or II) (if reported), codebook configuration (including codebook subset constraints), time domain behavior, used for CQI (channel quality Information, channel quality indicator) and PMI (precoding matrix information, precoding matrix indicator) frequency interval, measurement constraint configuration, etc. Each resource set may include: configurations of S≥1 CSI-RS resource sets (wherein, different sets correspond to different selections from all CSI-RS resource pools configured for the UE). The configuration of Ks≥1 CSI-RS resources in each set at least includes: resource element (resource element, RE) mapping, port number, time domain behavior and so on. Each of the L links in the CSImeasurement setting has: CSI reporting setting indication, resource setting indication, quality information to be measured (such as channel or interference), where a CSI reporting set can be related to one or more resource setting Multiple CSI reporting sets can be associated with the same resource setting.
可选的，上述CSI measurement setting，resource setting和resource可以通过在配置信息中的固定位置来使得UE获知所接收到的信息是什么信息，也可以通过他们的ID的不同来获知所接收到的信息是什么信息。Optionally, the above CSI measurement setting, resource setting and resource can enable the UE to know what information the received information is through the fixed position in the configuration information, and can also know the received information through the difference of their IDs what information.
具体的，一种可能的Time-delay-Config的描述如下：Specifically, a description of a possible Time-delay-Config is as follows:
Time-delay-Config SEQUENCE(SIZE(1..2))OF resource IDTime-delay-Config SEQUENCE(SIZE(1..2))OF resource ID
and/or SEQUENCE(SIZE(1..2))OF resource setting IDand/or SEQUENCE(SIZE(1..2))OF resource setting ID
and/or SEQUENCE(SIZE(1..2))OF CSI measurement setting IDand/or SEQUENCE(SIZE(1..2))OF CSI measurement setting ID
可以理解的是，一个resource setting ID可以包括一个或者多个资源ID，如果resource setting域中包括多个资源ID，可以预定义采用最小的ID或者通过其他指示信息指示该域中具体的资源ID用于传输时延测量，比如指示resource setting ID时增加索引index指示，该index指示用于指示该resource setting ID中的第几个资源用于进行传输时延测量，或者，指示resource setting ID下的source ID。类似的，一个CSI measurementsetting ID也可以包括一个或多个resource setting ID，也可以通过预定义或其他指示信息来使UE确定具体的用于传输时延测量的资源。It can be understood that a resource setting ID can include one or more resource IDs. If the resource setting field includes multiple resource IDs, the smallest ID can be predefined or the specific resource ID in the field can be indicated by other indication information. In the transmission delay measurement, for example, when indicating the resource setting ID, add the index index indication, the index indication is used to indicate which resource in the resource setting ID is used for transmission delay measurement, or indicate the source under the resource setting ID ID. Similarly, a CSI measurement setting ID may also include one or more resource setting IDs, and the UE may determine specific resources for transmission delay measurement through predefined or other indication information.
比如resource setting ID中包括的resource ID为2,3,5。则当index为1时，表示第一个resource，即resource ID为2对应的RS resource；当index为2时，表示第二个resource，即resource ID为3对应的resource；以此类推。或者当index为0时，表示第一个resource，即resource ID为2对应的resource；当index为1时，表示第二个resource，即RSresource ID为3对应的resource；以此类推。For example, the resource IDs included in the resource setting ID are 2, 3, and 5. Then, when the index is 1, it means the first resource, that is, the RS resource corresponding to the resource ID of 2; when the index is 2, it means the second resource, that is, the resource corresponding to the resource ID of 3; and so on. Or when the index is 0, it means the first resource, that is, the resource corresponding to resource ID 2; when the index is 1, it means the second resource, that is, the resource corresponding to RSresource ID 3; and so on.
类似的，第二指示信息用于指示第二参考信号用于传输时延的测量包括：Similarly, the second indication information used to indicate that the second reference signal is used for transmission delay measurement includes:
所述第二指示信息包括在信道状态信息测量集合域，信道状态信息报告集合域，或者，参考信号资源域中的至少一项中，所述第一指示信息用于指示所述信道状态信息测量集合域，信道状态信息报告集合域，或者，参考信号资源域中的至少一项中所包括的参考信号资源标识中的一个所对应的参考信号为第二参考信号,所述第二参考信号用于传输时延的测量。The second indication information is included in at least one of the channel state information measurement set field, channel state information report set field, or reference signal resource field, and the first indication information is used to indicate that the channel state information measurement The set field, the channel state information report set field, or the reference signal corresponding to one of the reference signal resource identifiers included in at least one of the reference signal resource fields is a second reference signal, and the second reference signal uses For the measurement of transmission delay.
第二指示信息具体如何指示可以参考前述第一指示信息的指示方式，在此不予赘述。How the second indication information specifies how to indicate may refer to the foregoing indication manner of the first indication information, which will not be repeated here.
可以理解的是，第一指示信息和第二指示信息可以包括在同一个Time-delay-Config中时，可以通过预定义或固定位置或指示信息区分是第一指示信息还是第二指示信息。第一指示信息和第二指示信息也可以包括在不同的Time-delay-Config中，这时可以通过不同的Time-delay-Config的固定位置来使UE区分第一指示信息和第二指示信息，也可以通过不同的Time-delay-Config ID来进行区分，在此不予赘述。It can be understood that when the first indication information and the second indication information may be included in the same Time-delay-Config, the first indication information or the second indication information may be distinguished by a predefined or fixed position or indication information. The first indication information and the second indication information may also be included in different Time-delay-Configs, and at this time, the UE may distinguish the first indication information from the second indication information through the fixed positions of different Time-delay-Configs, It can also be distinguished by different Time-delay-Config IDs, which will not be repeated here.
在传输时延差测量的情况下，一种可能的实施方式中，所述第一参考信号为用于传输时延测量的参考基线。In the case of transmission delay difference measurement, in a possible implementation manner, the first reference signal is a reference baseline for transmission delay measurement.
这种方式下，获知第一参考信号和/或第二参考信号用于传输时延的获得的方式可以为：In this way, the way to know the first reference signal and/or the second reference signal for obtaining the transmission delay may be:
方式一，所述第一指示信息还用于指示所述第一参考信号为用于传输时延测量的参考基线。Way 1, the first indication information is also used to indicate that the first reference signal is a reference baseline for transmission delay measurement.
这种方式下，所述第一指示信息还用于指示所述第一参考信号为用于传输时延测量的参考基线可以包括：In this manner, the first indication information is also used to indicate that the first reference signal is a reference baseline for transmission delay measurement may include:
所述第一指示信息包括在第一信息域中，所述第一信息域用于指示用于传输时延测量的参考基线的信息。The first indication information is included in a first information field, and the first information field is used to indicate reference baseline information for transmission delay measurement.
可选的，所述第一信息域还包括除了第一指示信息之外的第三指示信息，所述第三指示信息用于指示用于传输时延测量的另一参考基线的信息。Optionally, the first information field further includes third indication information in addition to the first indication information, where the third indication information is used to indicate information of another reference baseline used for transmission delay measurement.
用于传输时延测量的参考基线的信息的配置可以通过高层信令如RRC信令或MAC(media access control)信令进行指示，也可以通过物理层信令，如DCI信令，进行指示。也可以通过高层信令和物理层信令共同指示的方式，比如，通过高层信令进行多种配置的指示，通过物理层信令使能其中的一种或多种配置。比如，通过使能第一参考信号作为用于传输时延测量的参考基线使UE获知传输时延测量的参考基线为第一参考信号。The configuration of the reference baseline information for transmission delay measurement may be indicated through high-layer signaling such as RRC signaling or MAC (media access control) signaling, or through physical layer signaling such as DCI signaling. It may also be indicated through high-layer signaling and physical layer signaling, for example, multiple configurations are indicated through high-layer signaling, and one or more configurations are enabled through physical layer signaling. For example, enabling the first reference signal as the reference baseline for transmission delay measurement enables the UE to learn that the reference baseline for transmission delay measurement is the first reference signal.
在使能的参考基线为一个时，所述配置信息可以不用另行指示第二参考信号用于传输时延的测量时所参考的基线为哪个资源的信号了。When there is one enabled reference baseline, the configuration information does not need to additionally indicate which resource signal the second reference signal refers to when the transmission delay is measured.
在使能的参考基线或指示的参考基线有一个或多于一个的情况下，所述配置信息还可以包括第四指示信息，所述第四指示信息用于指示第二参考信号用于传输时延的测量时所参考的基线为所述第一参考信号，或者，前述第二指示信息还用于指示第二参考信号用于传输时延的测量时所参考的基线为所述第一参考信号。When there is one or more than one reference baseline or indicated reference baseline, the configuration information may further include fourth indication information, and the fourth indication information is used to indicate that when the second reference signal is used for transmission The baseline referenced during the delay measurement is the first reference signal, or the aforementioned second indication information is also used to indicate that the second reference signal is used for the transmission delay measurement. The reference baseline used during the transmission delay measurement is the first reference signal .
示例的，第一信息域可以为时延基线Time-delay-baseline域，该域可以包括资源集合标识(resource setting ID)，CSI测量集合ID(CSI measurement setting ID)或者资源ID(resource ID)中的一个或多个。第一信息域包括所述第一指示信息，这样，第一指示信息可以用于指示第一参考信号可以为用于传输时延(差)测量的参考基线的信息。第一指示信息可以为所述第一参考信号的资源ID，或者，第一参考信号所属的资源集合ID，或者，第一参考信号所属的CSI measurement setting ID，或者，它们中的一个或多个的组合。具体可以参考前述Time-delay-Config域的描述。For example, the first information field may be a delay baseline Time-delay-baseline field, and this field may include a resource set identifier (resource setting ID), a CSI measurement set ID (CSI measurement setting ID) or a resource ID (resource ID) one or more of . The first information field includes the first indication information. In this way, the first indication information may be used to indicate that the first reference signal may be information of a reference baseline for transmission delay (difference) measurement. The first indication information may be the resource ID of the first reference signal, or the resource set ID to which the first reference signal belongs, or the CSI measurement setting ID to which the first reference signal belongs, or one or more of them The combination. For details, refer to the description of the aforementioned Time-delay-Config field.
第一信息域的配置可以与具体的第一参考信号的配置信息(如第一参考信号的时域行为，端口数等)一起传输，也可以分开传输。The configuration of the first information domain may be transmitted together with the specific configuration information of the first reference signal (such as the time domain behavior of the first reference signal, the number of ports, etc.), or may be transmitted separately.
UE可以通过第一信息域获得用于传输时延测量的参考基线。The UE may obtain a reference baseline for transmission delay measurement through the first information field.
UE还可以通过CSI measurement setting中的指示信息，或者，前述Time-delay-Config域中的信息获知需要进行传输时延差的上报，和/或，获知需要针对第二参考信号进行传输时延差的测量和/或反馈。这样，UE可以根据第二参考信号以及对应的参考基线，获得二者的传输时延差，进而上报该传输时延差的信息。The UE may also know that it needs to report the transmission delay difference through the indication information in the CSI measurement setting, or the information in the aforementioned Time-delay-Config field, and/or know that it needs to perform the transmission delay difference for the second reference signal measurement and/or feedback. In this way, the UE can obtain the transmission delay difference between the two according to the second reference signal and the corresponding reference baseline, and then report the information of the transmission delay difference.
可选的，无线网络设备也可以配置多个参考基线，比如每个参考基线可以增加一个标识信息。在CSI measurement setting中或前述Time-delay-Config域中指示第二参考信号的参考基线是哪个，进而UE可以进行对应的测量和上报。Optionally, the wireless network device may also be configured with multiple reference baselines, for example, each reference baseline may add identification information. Indicate which reference baseline of the second reference signal is in the CSI measurement setting or the aforementioned Time-delay-Config field, and then the UE can perform corresponding measurement and reporting.
参考基线的配置方法举例如下，其中，time-delay-baselineConfigID为时延基线配置标识域，Time-delay-baselineConfigID可以为具体的标识值，比如0,1,2,3，…，可以是自然数或者正整数。Time-delay-baseline-resource为基线参考资源信息域。The configuration method of the reference baseline is as follows, where time-delay-baselineConfigID is the delay baseline configuration identification field, and Time-delay-baselineConfigID can be a specific identification value, such as 0, 1, 2, 3, ..., which can be a natural number or positive integer. Time-delay-baseline-resource is the baseline reference resource information field.
或者可以多个配置信息放在一起，比如：Or multiple configuration information can be put together, such as:
或者or
Time-delay-baseline＝{time-delay-baseline={
time-delay-baselineConfigIDList sequence(SIZE(2..8))of Time-delay-baselineConfigIDtime-delay-baselineConfigIDList sequence(SIZE(2..8))of Time-delay-baselineConfigID
Time-delay-baseline-resourceList sequence(SIZE(2..8))of resourcesetting ID or resourceID or CSI measurement setting IDTime-delay-baseline-resourceList sequence(SIZE(2..8))of resourcesetting ID or resourceID or CSI measurement setting ID
}}
可选的，CSI measurement setting中配置举例如下，其中resouce-settingIDConfig用于指示资源集合ID，CSI-reporting-settingIDConfig用于指示CSI上报(或反馈)集合ID，time-delay-baselineConfigID用于指示时延参考基线的配置ID，time-delay-baseline用于指示时延参考基线ID。Optionally, the configuration example in CSI measurement setting is as follows, where resource-settingIDConfig is used to indicate the resource set ID, CSI-reporting-settingIDConfig is used to indicate the CSI report (or feedback) set ID, and time-delay-baselineConfigID is used to indicate the delay The configuration ID of the reference baseline, time-delay-baseline is used to indicate the delay reference baseline ID.
CSI measurement setting Config＝{CSI measurement setting Config = {

or time-delay-baseline resource setting ID or resource ID or CSImeasurement setting IDor time-delay-baseline resource setting ID or resource ID or CSImeasurement setting ID
}}
通过以上配置，UE可以获知第二参考信号用于传输时延的测量(具体第二参考信号可以为CSI measurement setting内的哪个资源，可以通过协议预定义或指示信息另行指示，请参考前述第二指示信息的描述，在此不予赘述)，以及第二参考信号所对应的资源信息，还可以获知第二参考信号用于传输时延的测量时所参考的时延基准。这样，UE就可以进行传输时延差的测量，进而进行传输时延差的信息的上报。可以理解的是，上述配置中第二指示信息可以为所述time-delay-baselineConfigID或time-delay-baseline，也就是说，第二指示信息既用于指示第二参考信号所对应的资源信息，也用于指示第二参考信号用于传输时延的测量时所参考的时延基准。可选的，第二指示信息还可以触发所述第二参考信号所对应的传输时延差的测量和/或上报。Through the above configuration, the UE can know that the second reference signal is used for the measurement of transmission delay (specifically which resource in the CSI measurement setting the second reference signal can be, which can be pre-defined by the protocol or otherwise indicated by the indication information, please refer to the aforementioned second The description of the indication information will not be repeated here), and the resource information corresponding to the second reference signal, and the delay reference referenced by the second reference signal for measuring the transmission delay can also be obtained. In this way, the UE can measure the transmission delay difference, and then report the transmission delay difference information. It can be understood that the second indication information in the above configuration may be the time-delay-baselineConfigID or time-delay-baseline, that is, the second indication information is used to indicate the resource information corresponding to the second reference signal, It is also used to indicate the delay reference referenced when the second reference signal is used to measure the transmission delay. Optionally, the second indication information may also trigger measurement and/or reporting of the transmission delay difference corresponding to the second reference signal.
具体的，配置多个参考基准的应用场景可能为：Specifically, the application scenarios for configuring multiple reference benchmarks may be:
协作集中包括多个小区或者每个小区包括多个波束时，为了便于测量协作传输时实际传输的小区间的时延差或者多个波束间的时延差，可以考虑配置多个参考基线。比如协作小区为1,2,3,4,5,6时，假设可能协作传输的小区组合为(1,2)、(1,3)、(4,5)、(4,6)。此时可以配置时延基线1为小区1发送的资源信息，时延基线2为小区4的资源信息。进一步只需要测量小区2和小区1，小区3和小区1，小区5与小区4，小区6与小区4的传输时延差中的至少一个即可。这样可以避免测量不必要的传输时延差，比如小区4与小区1，小区5与小区1，小区6与小区1的传输时延差，减少开销。When the coordination set includes multiple cells or each cell includes multiple beams, in order to facilitate the measurement of the actual transmission delay difference between cells or the delay difference between multiple beams during coordinated transmission, multiple reference baselines may be configured. For example, when the coordinated cells are 1, 2, 3, 4, 5, and 6, it is assumed that combinations of possible coordinated transmission cells are (1, 2), (1, 3), (4, 5), and (4, 6). At this time, delay baseline 1 can be configured as resource information sent by cell 1, and delay baseline 2 can be configured as resource information sent by cell 4. Further, it is only necessary to measure at least one of the transmission delay differences between cell 2 and cell 1, cell 3 and cell 1, cell 5 and cell 4, and cell 6 and cell 4. In this way, unnecessary measurement of transmission delay differences, such as transmission delay differences between cell 4 and cell 1, cell 5 and cell 1, and cell 6 and cell 1, can be avoided, reducing overhead.
比如假设CSI measurement setting 2为小区2对应的测量配置信息，CSImeasurement setting 3为小区3对应的测量配置信息，CSI measurement setting 5为小区5对应的测量配置信息，CSI measurement setting 6为小区6对应的测量配置信息。则时延基线配置信息可以如下：For example, assume that CSI measurement setting 2 is the measurement configuration information corresponding to cell 2, CSI measurement setting 3 is the measurement configuration information corresponding to cell 3, CSI measurement setting 5 is the measurement configuration information corresponding to cell 5, and CSI measurement setting 6 is the measurement configuration information corresponding to cell 6. configuration information. Then the delay baseline configuration information can be as follows:
可选的，上述时延基线配置也可以放在resource setting或者CSI reportingsetting域中，具体举例如下：Optionally, the above latency baseline configuration can also be placed in the resource setting or CSI reportingsetting domain, specific examples are as follows:
方式二，所述配置信息还包括第五指示信息，所述第五指示信息用于指示所述第一参考信号为用于传输时延测量的参考基线。In a second manner, the configuration information further includes fifth indication information, where the fifth indication information is used to indicate that the first reference signal is a reference baseline for transmission delay measurement.
用于传输时延测量的参考基线的信息的配置可以通过高层信令如RRC信令或MAC(media access control)信令进行指示，也可以通过物理层信令，如DCI信令，进行指示。也可以通过高层信令和物理层信令共同指示的方式，比如，通过高层信令进行多种配置的指示，通过物理层信令使能其中的一种或多种配置。比如，通过使能第一参考信号作为用于传输时延测量的参考基线使UE获知传输时延测量的参考基线为第一参考信号，比如前述第五指示信息用于所述使能。The configuration of the reference baseline information for transmission delay measurement may be indicated through high-layer signaling such as RRC signaling or MAC (media access control) signaling, or through physical layer signaling such as DCI signaling. It may also be indicated through high-layer signaling and physical layer signaling, for example, multiple configurations are indicated through high-layer signaling, and one or more configurations are enabled through physical layer signaling. For example, enabling the first reference signal as the reference baseline for transmission delay measurement enables the UE to know that the reference baseline for transmission delay measurement is the first reference signal, for example, the aforementioned fifth indication information is used for the enabling.
在使能的参考基线为一个时，所述配置信息可以不用另行指示第二参考信号用于传输时延的测量时所参考的基线为哪个资源的信号了。When there is one enabled reference baseline, the configuration information does not need to additionally indicate which resource signal the second reference signal refers to when the transmission delay is measured.
在使能的参考基线或指示的参考基线有一个或多于一个的情况下，所述配置信息还可以包括第四指示信息，所述第四指示信息用于指示第二参考信号用于传输时延的测量时所参考的基线为所述第一参考信号，或者，前述第二指示信息还用于指示第二参考信号用于传输时延的测量时所参考的基线为所述第一参考信号。When there is one or more than one reference baseline or indicated reference baseline, the configuration information may further include fourth indication information, and the fourth indication information is used to indicate that when the second reference signal is used for transmission The baseline referenced during the delay measurement is the first reference signal, or the aforementioned second indication information is also used to indicate that the second reference signal is used for the transmission delay measurement. The reference baseline used during the transmission delay measurement is the first reference signal .
示例的，可以在前述Time-delay-Config域中对应第一参考信号的资源域增加第五指示信息，如time-delay-baseline字段，该字段为1时，表示第一参考信号用作时延基准，为0时，表示第一参考信号不用做时延基准。还可以在对应第二参考信号的资源域中增加第四指示信息，所述第四指示信息可以为time-delay-baseline字段，该字段中的标识，可以指示第二参考信号用于传输时延的测量时所参考的基线，比如为第一参考信号的资源标识。For example, fifth indication information, such as the time-delay-baseline field, can be added to the resource field corresponding to the first reference signal in the aforementioned Time-delay-Config field. When this field is 1, it means that the first reference signal is used as a delay When reference is 0, it means that the first reference signal is not used as a delay reference.

Wherein, the information of the number of times of feedback is used to indicate the number of times of feedback of the transmission delay difference.
与非周期反馈相关的信息可以通过高层信令如RRC信令或MAC(media accesscontrol)信令进行指示，也可以通过物理层信令，如DCI信令，进行指示。也可以通过高层信令和物理层信令共同指示的方式，比如，通过高层信令进行多种配置的指示，通过物理层信令使能其中的一种或多种配置。The information related to the aperiodic feedback can be indicated through high layer signaling such as RRC signaling or MAC (media access control) signaling, or through physical layer signaling such as DCI signaling. It may also be indicated through high-layer signaling and physical layer signaling, for example, multiple configurations are indicated through high-layer signaling, and one or more configurations are enabled through physical layer signaling.
示例的，通过RRC信令进行指示，具体的，可以指示反馈的时频域资源信息，该时频域资源信息也可以是协议预定义的，比如，最后一个符号，或者频域上的第一个PRB或者最后一个PRB等，前述指示反馈的时频域资源信息也可以通过DCI信令进行指示。For example, RRC signaling is used to indicate. Specifically, the time-frequency domain resource information fed back can be indicated. The time-frequency domain resource information can also be predefined by the protocol, for example, the last symbol, or the first symbol in the frequency domain PRB or the last PRB, etc., the time-frequency domain resource information indicated for feedback may also be indicated through DCI signaling.
可选的，还可以通过DCI信令发送用于指示所述传输时延差的反馈的开始的信息(也可以简称为触发信息)，UE接收到该触发信息后可以在规定的时刻进行反馈，比如默认在若干个子帧后进行反馈，如4个子帧。Optionally, information indicating the start of the feedback of the transmission delay difference (also referred to as trigger information) may also be sent through DCI signaling, and the UE may perform feedback at a specified time after receiving the trigger information, For example, feedback is performed after several subframes by default, such as 4 subframes.
具体的，可以在DCI中配置传输时延的触发信息，比如通过1bit指示需要UE上报传输时延。Specifically, the trigger information of the transmission delay can be configured in the DCI, for example, 1 bit indicates that the UE needs to report the transmission delay.
可选的，还可以基于RRC信令中的配置触发传输时延(或传输时延差)的测量和/或上报。Optionally, the measurement and/or reporting of the transmission delay (or transmission delay difference) may also be triggered based on the configuration in the RRC signaling.
比如，在PUCCH中反馈传输时延和/或传输时延差的信息，可以通过指示PUCCH的传输格式，如格式4用于指示传输时延(或传输时延差)的测量和/或上报，触发UE进行传输时延(或传输时延差)的测量和/或上报；或者，在CSI中反馈传输时延或传输时延差的信息，可以通过指示CSI的反馈type，如type 10用于指示支持传输时延(或传输时延差)的测量和/或上报，触发UE进行传输时延(或传输时延差)的测量和/或上报，其中，传输时延或传输时延差的信息可以与CSI联合编码，比如和PMI和CQI联合编码后进行上报，也可以独立编码，比如独立编码后与RI一起上报，或者，独立编码后独立上报(即与CSI的上报不复用时域或频域资源)。For example, the transmission delay and/or transmission delay difference information fed back in the PUCCH can be indicated by indicating the transmission format of the PUCCH, such as format 4, which is used to indicate the measurement and/or reporting of the transmission delay (or transmission delay difference), Trigger the UE to measure and/or report the transmission delay (or transmission delay difference); or, to feed back the transmission delay or transmission delay difference information in the CSI, you can indicate the feedback type of the CSI, such as type 10 for Indicates that the measurement and/or reporting of transmission delay (or transmission delay difference) is supported, and triggers the UE to perform measurement and/or reporting of transmission delay (or transmission delay difference), wherein the transmission delay or transmission delay difference The information can be jointly coded with CSI, such as jointly coded with PMI and CQI and reported, or can be coded independently, such as independently coded and reported together with RI, or independently coded and reported independently (that is, the time domain is not multiplexed with the CSI report) or frequency domain resources).
可选的，非周期反馈的次数为多次的情况下，可以在RRC信令或者DCI中指示反馈的开始时刻和结束时刻。指示反馈的开始时刻和结束时刻的方式可以为以下方式中的一种或多种：Optionally, when the number of times of aperiodic feedback is multiple, the start time and end time of feedback may be indicated in RRC signaling or DCI. The way of indicating the start time and end time of the feedback may be one or more of the following ways:
方式一，触发信息触发UE反馈多次，比如触发一次UE反馈5次，这里的反馈次数可以是协议预定义的。Mode 1, the trigger information triggers the UE to feed back multiple times, for example, once triggering the UE to feed back 5 times, the number of times of feedback here may be predefined by the protocol.
进一步的，触发信息还可以为反馈次数信息的指示。Further, the trigger information may also be an indication of feedback frequency information.
方式二，指示反馈次数信息。Mode 2, indicating feedback frequency information.
比如：for example:
触发信息可以为半静态反馈semi-persistent report字段，占1bit，示例的，0表示正常触发一次上报一次，1表示为多次反馈的情况。The trigger information can be a semi-persistent report field for semi-static feedback, which occupies 1 bit. For example, 0 means that it is normally triggered once and reported once, and 1 means that it is reported multiple times.
反馈次数的信息可以为上报次数report number字段，占1bit或者2bit或者其他，具体可以根据最大的上报次数为确定所占bit数，该信息指示具体的反馈次数。The feedback frequency information may be the reporting frequency report number field, occupying 1 bit or 2 bits or others. Specifically, the occupied bit number may be determined according to the maximum reporting frequency, and the information indicates the specific feedback frequency.
反馈次数信息可以通过枚举反馈次数的方式进行指示，比如在上报次数reportnumber字段，用枚举的值进行指示，如report number ENUMERATED{5,10,15,20,spare1}。Feedback times information can be indicated by enumerating feedback times, for example, in the reported times reportnumber field, an enumerated value is used for indication, such as report number ENUMERATED{5,10,15,20,spare1}.
方式三，指示反馈开始时刻和结束时刻，比如开始时刻为帧号5，结束时刻为帧号25。Mode 3, indicating the feedback start time and end time, for example, the start time is frame number 5, and the end time is frame number 25.
比如，StartReportFrameNumber表示开始上报的帧号，StopReportFrameNumber表示结束上报的帧号。For example, StartReportFrameNumber indicates the frame number to start reporting, and StopReportFrameNumber indicates the frame number to end reporting.
StartReportFrameNumber ENUMERATED{5,10,15,20,25,spare1}StartReportFrameNumber ENUMERATED{5,10,15,20,25,spare1}
StopReportFrameNumber ENUMERATED{5,10,15,20,25,spare1}StopReportFrameNumber ENUMERATED{5,10,15,20,25,spare1}
可以理解的是，上述帧号，也可以是其他时间单位，比如子帧，时隙等。It can be understood that, the above frame number may also be other time units, such as subframe, time slot and so on.
方式四，上报的时候发送触发消息指示开始上报，结束的时候再发送触发消息指示结束上报。Mode 4: Send a trigger message to indicate the start of the report when reporting, and send a trigger message to indicate the end of the report at the end of the report.
比如StartReportTrigger表示存在该消息则表示开始上报，该上报行为可以从下一时刻生效或者下X个时刻生效，X可以为协议预定义的，或通过其他信令指示的。For example, if the StartReportTrigger indicates that the message exists, it means that the report will start. The reporting behavior can take effect from the next time or the next X time, and X can be predefined by the protocol or indicated by other signaling.
StopReport Trigger表示存在该消息则表示停止上报，该结束上报行为也可以下一时刻生效或者下Y个时刻生效，Y可以为协议预定义的，或通过其他信令指示的。The StopReport Trigger indicates that the report is stopped if the message exists, and the reporting end behavior can also take effect at the next moment or at the next Y moment, and Y can be predefined by the protocol or indicated by other signaling.
可选的，所述传输时延和/或传输时延差的信息可以包括在上行控制信号(信道)中，如物理上行控制信道(physical uplink control channel，PUCCH)中，或者，可以包括在信道状态信息(channel state information，CSI)中。示例的，可以通过新增格式，或是重新定义已有格式(如在已有格式中增加相应域)的方式进行传输。Optionally, the transmission delay and/or transmission delay difference information may be included in an uplink control signal (channel), such as a physical uplink control channel (physical uplink control channel, PUCCH), or may be included in a channel In the channel state information (CSI). For example, the transmission may be performed by adding a new format, or redefining an existing format (such as adding a corresponding field in an existing format).
所述传输时延和/或传输时延差的信息包括在CSI中的情况下，可选的，UE还可以接收第七指示信息，第七指示信息用于指示传输时延和/或传输时延差的信息包括在信道状态信息中进行反馈。可以理解的是，该第七指示信息也可以用于触发传输时延和/或传输时延差的信息的获得和/或反馈。In the case where the transmission delay and/or transmission delay difference information is included in the CSI, optionally, the UE may also receive seventh indication information, where the seventh indication information is used to indicate the transmission delay and/or transmission time The delay information is included in the channel state information for feedback. It can be understood that the seventh indication information may also be used to trigger acquisition and/or feedback of transmission delay and/or transmission delay difference information.
可选的，所述第七指示信息可以为一种CSI的反馈类型的信息。当UE收到该CSI的反馈类型的信息时，UE获知传输时延和/或传输时延差的信息包括在信道状态信息中进行反馈。Optionally, the seventh indication information may be information of a CSI feedback type. When the UE receives the feedback type information of the CSI, the UE knows that the transmission delay and/or transmission delay difference information is included in the channel state information for feedback.
比如，CSI的反馈类型为类型(type)10反馈，则表示支持传输时延和/或传输时延差的反馈。具体的，传输时延和/或传输时延差可以与CSI，如PMI和CQI，联合编码后进行反馈，也可以独立编码后和CSI，如RI，一起反馈。For example, if the feedback type of the CSI is type (type) 10 feedback, it indicates that the feedback of transmission delay and/or transmission delay difference is supported. Specifically, the transmission delay and/or the transmission delay difference may be jointly encoded with CSI, such as PMI and CQI, and then fed back, or may be independently encoded and fed back together with CSI, such as RI.
所述传输时延和/或传输时延差的信息包括在上行控制信号(信道)中的情况下，可以为上行控制信道的反馈增加一种传输格式，比如格式4，则可以表示需要反馈在上行控制信道中反馈传输时延和/或传输时延差的信息。可以理解的是，该传输格式也可以用于触发传输时延和/或传输时延差的信息的获得和/或反馈。In the case where the transmission delay and/or transmission delay difference information is included in the uplink control signal (channel), a transmission format can be added to the feedback of the uplink control channel, such as format 4, which can indicate that feedback is required in Information about transmission delay and/or transmission delay difference is fed back in the uplink control channel. It can be understood that the transmission format may also be used to trigger acquisition and/or feedback of information on transmission delay and/or transmission delay difference.
可选的，所述传输时延和/或传输时延差的反馈可以通过将传输时延和/或传输时延差经过量化后或经过编码后进行反馈，比如通过若干比特，如3bits或4bits进行反馈。反馈的是传输时延和/或传输时延差的信息，比如索引信息。Optionally, the feedback of the transmission delay and/or the transmission delay difference may be fed back by quantizing or encoding the transmission delay and/or the transmission delay difference, for example, through several bits, such as 3 bits or 4 bits Give feedback. What is fed back is information about transmission delay and/or transmission delay difference, such as index information.
比如传输时延差可以为100ns,200ns,300ns，…,-100ns,-200ns,-300ns，通过如下表格进行索引。可以理解的是，索引和数值只是举例说明，也可以是其他的值。For example, the transmission delay difference can be 100ns, 200ns, 300ns, ..., -100ns, -200ns, -300ns, indexed by the following table. It can be understood that the indices and values are just examples, and other values are also possible.
或者16Ts,32Ts,64Ts,128Ts,256Ts,…,-16Ts,-32Ts,-64Ts,-128Ts,-256Ts,……通过如下表格进行索引。其中，Ts为一种时间单位，如LTE系统中，Ts＝1/(15000*2048)秒(s)，其中15000为子载波间隔，2048为采样点数。索引和数值只是举例说明，也可以是其他的值。Or 16Ts, 32Ts, 64Ts, 128Ts, 256Ts, ..., -16Ts, -32Ts, -64Ts, -128Ts, -256Ts, ... are indexed through the following table. Wherein, Ts is a time unit, such as in the LTE system, Ts=1/(15000*2048) seconds (s), where 15000 is the subcarrier interval, and 2048 is the number of sampling points. Indexes and values are just examples, and other values are possible.
或者通过其他的量化格式和取值进行反馈，在此不予赘述。Alternatively, feedback may be performed through other quantization formats and values, which will not be repeated here.
这样，通过如图3所示的信息传输的方法，可以使得UE可以根据参考信号获得传输时延和/或传输时延差，进而，通过UE将传输时延和/或传输时延差发送给无线网络设备，可以使得与UE进行通信的至少两个无线网络设备中的至少一个进行相位的调整，进而使得UE从这至少两个无线网络设备收到的数据的传输时延差小于门限值，达到接近理论上同时接收的效果，进而提高传输性能。In this way, through the information transmission method shown in Figure 3, the UE can obtain the transmission delay and/or the transmission delay difference according to the reference signal, and then, the UE sends the transmission delay and/or the transmission delay difference to the The wireless network device may enable at least one of at least two wireless network devices communicating with the UE to perform phase adjustment, so that the transmission delay difference of data received by the UE from the at least two wireless network devices is less than a threshold value , to achieve the effect close to the theoretical simultaneous reception, thereby improving the transmission performance.

图4b提供了一种用户设备UE的结构示意图。该UE可适用于图2所示出的系统中和/或如图1a和图1b所示的场景中。为了便于说明，图4b仅示出了用户设备的主要部件。如图4b所示，用户设备100包括处理器、存储器、控制电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对整个用户设备进行控制，执行软件程序，处理软件程序的数据，例如用于支持UE执行附图3部分所描述的动作。存储器主要用于存储软件程序和数据，例如存储上述实施例中所描述的码本。控制电路主要用于基带信号与射频信号的转换以及对射频信号的处理。控制电路和天线一起也可以叫做收发器，主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。Fig. 4b provides a schematic structural diagram of a user equipment UE. The UE may be applicable to the system shown in FIG. 2 and/or the scenarios shown in FIG. 1a and FIG. 1b. For ease of illustration, Fig. 4b only shows the main components of the user equipment. As shown in Fig. 4b, the user equipment 100 includes a processor, a memory, a control circuit, an antenna, and an input and output device. The processor is mainly used to process communication protocols and communication data, control the entire user equipment, execute software programs, and process data of software programs, for example, to support the UE to perform the actions described in part 3 of the accompanying drawing. The memory is mainly used for storing software programs and data, such as storing the codebook described in the above embodiments. The control circuit is mainly used for conversion of baseband signal and radio frequency signal and processing of radio frequency signal. The control circuit and the antenna can also be called a transceiver, which is mainly used to send and receive radio frequency signals in the form of electromagnetic waves. Input and output devices, such as touch screens, display screens, and keyboards, are mainly used to receive data input by users and output data to users.
当用户设备开机后，处理器可以读取存储单元中的软件程序，解释并执行软件程序的指令，处理软件程序的数据。当需要通过无线发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到用户设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。When the user equipment is turned on, the processor can read the software program in the storage unit, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor performs baseband processing on the data to be sent, and then outputs the baseband signal to the radio frequency circuit. When data is sent to the user equipment, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor, and the processor converts the baseband signal into data and processes the data.
本领域技术人员可以理解，为了便于说明，图4b仅示出了一个存储器和处理器。在实际的用户设备中，可以存在多个处理器和存储器。存储器也可以称为存储介质或者存储设备等，本发明实施例对此不做限制。Those skilled in the art can understand that, for ease of illustration, FIG. 4b only shows a memory and a processor.
