为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3^rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(massive Machine-Type Communications，mMTC)。With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the^3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

一方面，eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，例如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。On the one hand, eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety assurance, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of the module.

在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧耦合(tight interworking)的工作模式。In the early deployment of NR, complete NR coverage is difficult to obtain, so typical network coverage is wide-area LTE coverage and NR island coverage mode. And a lot of LTE is deployed in sub-6GHz, and there is very little sub-6GHz spectrum available for 5G. Therefore, NR must study the spectrum application above 6GHz, while the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect the early investment of mobile operators in LTE, a working mode of tight interworking between LTE and NR is proposed.

RRC状态

RRC status

5G为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义了一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。其中，5G defines a new Radio Resource Control (RRC) state, that is, RRC_INACTIVE state, in order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. in,

1)RRC_IDLE状态(简称为空闲(idle)态)：移动性为基于UE的小区选择重选，寻呼由核心网(Core Network，CN)发起，寻呼区域由CN配置。基站侧不存在UE上下文，不存在RRC连接。1) RRC_IDLE state (referred to as idle state): mobility is UE-based cell selection reselection, paging is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no UE context and no RRC connection on the base station side.

2)RRC_CONNECTED状态(简称为连接(connected)态)：存在RRC连接，基站侧和UE侧存在UE上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。2) RRC_CONNECTED state (referred to as connected state): there is an RRC connection, and a UE context exists on the base station side and the UE side. The network side knows that the location of the UE is at the specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

3)RRC_INACTIVE状态(简称为非激活(inactive)态)：移动性为基于UE的小区选择重选，存在CN-NR之间的连接，UE上下文存在某个基站上，寻呼由RAN触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。3) RRC_INACTIVE state (referred to as inactive state): mobility is UE-based cell selection reselection, there is a connection between CN-NR, UE context exists on a certain base station, paging is triggered by RAN, based on The paging area of the RAN is managed by the RAN, and the network side knows the location of the UE based on the paging area level of the RAN.

多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)

Multimedia Broadcast Multicast Service (MBMS)

MBMS是一种通过共享网络资源从一个数据源向多个终端设备传送数据的技术，该技术在提供多媒体业务的同时能有效地利用网络资源，实现较高速率(如256kbps)的多媒体业务的广播和组播。MBMS is a technology that transmits data from a data source to multiple terminal devices by sharing network resources. This technology can effectively utilize network resources while providing multimedia services, and realize the broadcast of multimedia services at higher rates (such as 256kbps). and multicast.

由于MBMS频谱效率较低，不足以有效地承载和支撑手机电视类型业务的运营。因此在LTE中，3GPP明确提出增强对下行高速MBMS业务的支持能力，并确定了对物理层和空中接口的设计要求。Due to the low spectral efficiency of MBMS, it is not enough to effectively carry and support the operation of mobile TV type services. Therefore, in LTE, 3GPP clearly proposes to enhance the support capability for downlink high-speed MBMS services, and determines the design requirements for the physical layer and air interface.

3GPP R9将演进的MBMS(evolved MBMS，eMBMS)引入到LTE中。eMBMS提出了单频率网络(Single Frequency Network，SFN)的概念，即多媒体广播多播服务单频率网络(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)，MBSFN采用统一频率在所有小区同时发送业务数据，但是要保证小区间的同步。这种方式可以极大的提高小区整体信噪比分布，频谱效率也会相应的大幅提高。eMBMS基于IP多播协议实现业务的广播和多播。3GPP R9 introduced evolved MBMS (evolved MBMS, eMBMS) into LTE. eMBMS proposes the concept of Single Frequency Network (SFN), namely Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN), MBSFN uses a uniform frequency to send service data in all cells at the same time, but To ensure synchronization between cells. In this way, the overall signal-to-noise ratio distribution of the cell can be greatly improved, and the spectral efficiency will also be greatly improved accordingly. eMBMS implements service broadcast and multicast based on IP multicast protocol.

在LTE或增强的LTE(LTE-Advanced，LTE-A)中，MBMS只有广播承载模式，没有多播承载模式。此外，MBMS业务的接收适用于空闲态或者连接态的终端设备。In LTE or LTE-Advanced (LTE-Advanced, LTE-A), MBMS has only a broadcast bearer mode and no multicast bearer mode. In addition, the reception of the MBMS service is applicable to the terminal equipment in the idle state or the connected state.

3GPP R13中引入了单小区点对多点(Single Cell Point To Multiploint，SC-PTM)概念，SC-PTM基于MBMS网络架构。The concept of Single Cell Point To Multiploint (SC-PTM) was introduced in 3GPP R13, and SC-PTM is based on the MBMS network architecture.

MBMS引入了新的逻辑信道，包括单小区多播控制信道(Single Cell-Multicast Control Channel，SC-MCCH)和单小区多播传输信道(Single Cell-Multicast Transport Channel，SC-MTCH)。SC-MCCH和SC-MTCH被映射到下行共享信道(Downlink-Shared Channel，DL-SCH)上，进一步，DL-SCH被映射到物理下行共享信道(Physical Downlink Shared Channel，PDSCH)上，其中，SC-MCCH和SC-MTCH属于逻辑信道，DL-SCH属于传输信道，PDSCH属于物理信道。SC-MCCH和SC-MTCH不支持混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)操作。MBMS introduces new logical channels, including Single Cell Multicast Control Channel (SC-MCCH) and Single Cell Multicast Transport Channel (SC-MTCH). SC-MCCH and SC-MTCH are mapped to downlink shared channel (Downlink-Shared Channel, DL-SCH), further, DL-SCH is mapped to physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), wherein, SC - MCCH and SC-MTCH belong to logical channels, DL-SCH belongs to transport channels, and PDSCH belongs to physical channels. SC-MCCH and SC-MTCH do not support hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) operations.

MBMS引入了新的系统信息块(System Information Block，SIB)类型，即SIB20。具体地，通过SIB20来传输SC-MCCH的配置信息，一个小区只有一个SC-MCCH。SC-MCCH的配置信息包括：SC-MCCH的修改周期、SC-MCCH的重复周期、以及调度SC-MCCH的无线帧和子帧等信息。进一步，1)SC-MCCH的修改周期的边界满足SFN mod m＝0，其中，SFN代表边界的系统帧号，m是SIB20中配置的SC-MCCH的修改周期(即sc-mcch-ModificationPeriod)。2)调度SC-MCCH的无线帧满足：SFN mod mcch-RepetitionPeriod＝mcch-Offset，其中，SFN代表无线帧的系统帧号，mcch-RepetitionPeriod代表SC-MCCH的重复周期，mcch-Offset代表SC-MCCH的偏移量。3)调度SC-MCCH的子帧通过sc-mcch-Subframe指示。MBMS introduces a new system information block (System Information Block, SIB) type, namely SIB20. Specifically, the configuration information of the SC-MCCH is transmitted through the SIB20, and a cell has only one SC-MCCH. The configuration information of the SC-MCCH includes the modification period of the SC-MCCH, the repetition period of the SC-MCCH, and information such as the radio frame and subframe in which the SC-MCCH is scheduled. Further, 1) the boundary of the modification period of SC-MCCH satisfies SFN mod m=0, where SFN represents the system frame number of the boundary, and m is the modification period of SC-MCCH configured in SIB20 (ie sc-mcch-ModificationPeriod). 2) The radio frame for scheduling SC-MCCH satisfies: SFN mod mcch-RepetitionPeriod=mcch-Offset, where SFN represents the system frame number of the radio frame, mcch-RepetitionPeriod represents the repetition period of SC-MCCH, and mcch-Offset represents SC-MCCH offset. 3) The subframe in which the SC-MCCH is scheduled is indicated by sc-mcch-Subframe.

SC-MCCH通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度。一方面，引入新的无线网络临时标识(Radio Network Tempory Identity，RNTI)，即单小区RNTI(Single Cell RNTI，SC-RNTI)来识别用于调度SC-MCCH的PDCCH(如SC-MCCH PDCCH)，可选地，SC-RNTI固定取值为FFFC。另一方面，引入新的RNTI，即单小区通知RNTI(Single Cell Notification RNTI，SC-N-RNTI)来识别用于指示SC-MCCH的变更通知的PDCCH(如通知PDCCH)，可选地，SC-N-RNTI固定取值为FFFB；进一步，可以用DCI 1C的8个比特(bit)中的一个bit来指示变更通知。在LTE中，SC-PTM的配置信息基于SIB20配置的SC-MCCH，然后SC-MCCH配置SC-MTCH，SC-MTCH用于传输业务数据。The SC-MCCH is scheduled through the Physical Downlink Control Channel (PDCCH). On the one hand, a new wireless network temporary identity (Radio Network Tempory Identity, RNTI), that is, a single cell RNTI (Single Cell RNTI, SC-RNTI), is introduced to identify the PDCCH (such as SC-MCCH PDCCH) used for scheduling SC-MCCH, Optionally, the fixed value of SC-RNTI is FFFC. On the other hand, a new RNTI is introduced, that is, a single cell notification RNTI (Single Cell Notification RNTI, SC-N-RNTI) to identify the PDCCH (such as the notification PDCCH) used to indicate the change notification of the SC-MCCH, optionally, the SC The fixed value of -N-RNTI is FFFB; further, one of the 8 bits (bits) of DCI 1C can be used to indicate the change notification. In LTE, the configuration information of the SC-PTM is based on the SC-MCCH configured by the SIB20, and then the SC-MCCH configures the SC-MTCH, and the SC-MTCH is used to transmit service data.

具体地，SC-MCCH只传输一个消息(即SCPTMConfiguration)，该消息用于配置SC-PTM的配置信息。SC-PTM的配置信息包括：临时移动组标识(Temporary Mobile Group Identity，TMGI)、会话标识(seession id)、组RNTI(Group RNTI，G-RNTI)、非连续接收(Discontinuous Reception，DRX)配置信息以及邻区的SC-PTM业务信息等。需要说明的是，R13中的SC-PTM不支持健壮性包头压缩(Robust Header Compression，ROHC)功能。Specifically, the SC-MCCH only transmits one message (ie, SCPTMConfiguration), which is used to configure the configuration information of the SC-PTM. The configuration information of SC-PTM includes: Temporary Mobile Group Identity (TMGI), session identifier (session id), group RNTI (Group RNTI, G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information And the SC-PTM service information of neighboring cells, etc. It should be noted that the SC-PTM in R13 does not support the Robust Header Compression (ROHC) function.

SC-PTM的下行非连续的接收是通过以下参数控制的：onDurationTimerSCPTM、 drx-InactivityTimerSCPTM、SC-MTCH-SchedulingCycle、以及SC-MTCH-SchedulingOffset。Downlink discontinuous reception of SC-PTM is controlled by the following parameters: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.

当满足[(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)＝SC-MTCH-SchedulingOffset时，启动定时器onDurationTimerSCPTM；When [(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset is satisfied, the timer onDurationTimerSCPTM is started;

当接收到下行PDCCH调度时，启动定时器drx-InactivityTimerSCPTM；When receiving the downlink PDCCH scheduling, start the timer drx-InactivityTimerSCPTM;

只有当定时器onDurationTimerSCPTM或drx-InactivityTimerSCPTM运行时才接收下行SC-PTM业务。The downstream SC-PTM service is received only when the timer onDurationTimerSCPTM or drx-InactivityTimerSCPTM is running.

SC-PTM业务连续性采用基于SIB15的MBMS业务连续性概念，即“SIB15+MBMSInterestIndication”方式。空闲态的终端设备的业务连续性基于频率优先级的概念。SC-PTM business continuity adopts the concept of MBMS business continuity based on SIB15, namely "SIB15+MBMSInterestIndication" mode. The service continuity of terminal equipment in idle state is based on the concept of frequency priority.

根据上述描述可知，SC-PTM的配置是基于SIB20配置SC-MCCH，然后基于SC-MCCH配置SC-MTCH，SC-MTCH用于传输业务数据。According to the above description, the configuration of the SC-PTM is to configure the SC-MCCH based on the SIB20, and then configure the SC-MTCH based on the SC-MCCH, and the SC-MTCH is used to transmit service data.

需要说明的是，上述方案中的MBMS业务包括但不局限于多播业务、组播业务、MBS业务等。本申请实施例以MBS业务为例进行说明，“MBS业务”的描述也可以被替换为“多播业务”或者“组播业务”或者“MBMS业务”。It should be noted that the MBMS services in the above solution include but are not limited to multicast services, multicast services, and MBS services. The embodiments of the present application are described by taking the MBS service as an example, and the description of "MBS service" may also be replaced with "multicast service" or "multicast service" or "MBMS service".

在NR系统中，很多场景需要支持组播类型和广播类型的业务需求，例如车联网中，工业互联网中等。所以在NR中引入组播类型和广播类型的MBS业务是有必要的。需要说明的是，组播类型的MBS业务是指通过组播方式传输的MBS业务。广播类型的MBS业务是指通过广播方式传输的MBS业务。In the NR system, many scenarios need to support the service requirements of multicast type and broadcast type, such as in the Internet of Vehicles, industrial Internet, etc. Therefore, it is necessary to introduce MBS services of multicast type and broadcast type into NR. It should be noted that the MBS service of the multicast type refers to the MBS service transmitted in a multicast manner. The broadcast-type MBS service refers to the MBS service transmitted in a broadcast manner.

在NR系统中，对于组播类型的MBS业务来说，MBS业务是发给某个组中的所有终端设备。终端设备在RRC连接状态下接收组播类型的MBS业务，终端设备可以通过PTM方式或者PTP方式接收组播类型的MBS业务数据。其中，PTM方式的MBS业务数据通过网络侧配置的G-RNTI来加扰对应的调度信息，PTP方式的MBS业务数据通过C-RNTI来加扰对应的调度信息。In the NR system, for the MBS service of multicast type, the MBS service is sent to all terminal devices in a certain group. The terminal device receives the multicast MBS service in the RRC connection state, and the terminal device can receive the multicast MBS service data in the PTM mode or the PTP mode. Wherein, the MBS service data in the PTM mode scrambles the corresponding scheduling information through the G-RNTI configured on the network side, and the MBS service data in the PTP mode scrambles the corresponding scheduling information through the C-RNTI.

组播类型的MBS业务的可靠性要求比较高，通过PTP方式接收MBS业务数据可以实现无线链路层控制(Radio Link Control，RLC)确认模式(Acknowledged Mode，AM)，因而可以保证可靠性要求较高的MBS业务数据传输。基于此，提出了本申请实施例的以下技术方案。本申请实施例的技术方案，一方面，终端设备在第一条件满足的情况下向网络设备发送第一信息，通过第一信息触发网络设备执行第一传输方式和第二传输方式之间的切换；另一方面，终端设备在第二条件满足的情况下向网络设备发送PDCP状态报告，从而最大程度的保障MBS业务接收的可靠性。The reliability requirements of multicast MBS services are relatively high. Receiving MBS service data through PTP can realize Radio Link Control (RLC) Acknowledged Mode (AM), thus ensuring higher reliability requirements. High MBS service data transmission. Based on this, the following technical solutions of the embodiments of the present application are proposed. In the technical solutions of the embodiments of the present application, on the one hand, the terminal device sends first information to the network device when the first condition is satisfied, and triggers the network device to perform switching between the first transmission mode and the second transmission mode through the first information On the other hand, the terminal device sends a PDCP status report to the network device under the condition that the second condition is satisfied, so as to ensure the reliability of MBS service reception to the greatest extent.
