Description

一种被用于无线通信的方法和设备 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及无线通信的广播组播业务，业务接收的连续性等方面的方法和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。
在通信中，无论是LTE(Long Term Evolution，长期演进)还是5G NR都会涉及到可靠的信息的准确接收，优化的能效比，信息有效性的确定，灵活的资源分配，可伸缩的系统结构，高效的非接入层信息处理，较低的业务中断和掉线率，对低功耗支持，这对基站和用户设备的正常通信，对资源的合理调度，对系统负载的均衡都有重要的意义，可以说是高吞吐率，满足各种业务的通信需求，提高频谱利用率，提高服务质量的基石，无论是eMBB(enhanced Mobile BroadBand，增强的移动宽带)，URLLC(Ultra Reliable Low Latency Communication，超高可靠低时延通信)还是eMTC(enhanced Machine Type Communication，增强的机器类型通信)都不可或缺的。同时在IIoT(Industrial Internet of Things，工业领域的物联网中，在V2X(Vehicular to X，车载通信)中，在设备与设备之间通信(Device to Device)，在非授权频谱的通信中，在用户通信质量监测，在网络规划优化，在NTN(Non Territorial Network，非地面网络通信)中，在TN(Territorial Network，地面网络通信)中，在双连接(Dual connectivity)系统中，在无线资源管理以及多天线的码本选择中，在信令设计，邻区管理，业务管理，在波束赋形中都存在广泛的需求，信息的发送方式分为广播和单播，两种发送方式都是5G系统必不可少的，因为它们对满足以上需求十分有帮助。UE与网络连接的方式可以是直接连接也可以通过中继连接。
随着系统的场景和复杂性的不断增加，对降低中断率，降低时延，增强可靠性，增强系统的稳定性，对业务的灵活性，对功率的节省也提出了更高的要求，同时在系统设计的时候还需要考虑不同系统不同版本之间的兼容性。
本申请中的概念、术语与缩写的含义可参考3GPP标准，包括但不限于：

发明内容
多播广播业务(Multicast and Broadcast Service,MBS)，是5G网络中的重要通信方式，经常用于视频的传输，占用较大的带宽，功率消耗较大，另一方面MBS也可能应用到大量IoT设备中，以减少网络资源的消耗，节省功率对IoT设备十分重要。因此使用MBS业务的终端对节省功率有着普遍的需求。一种可能的节省功率的方式是在没有其它业务的时候进入RRC不活跃态(RRC_INACTIVE)接收MBS业务。在RRC不活跃态接收多播业务，尤其是从RRC连接态进入RRC不活跃态连续的接收MBS业务是一个挑战，这在之前的协议是不支持的。当一个用户从RRC连接态开始就接收一个MBS业务，然后为了节省电力进入RRC不活跃态继续接收，这会带来一个连续接收的问题。在现有技术中，不存在从RRC连接态到RRC不活跃态连续接收的问题，因为一般情况下，用户已经完成了当前的业务之后才进入RRC不活跃态。因此，现有技术中，当用户设备进入RRC不活跃态后，首先需要选择一个驻留的小区，一般来说是根据信号强度选择那个最强的，但是要接收的MBS业务可能并不在那个小区上提供，或者即使提供可能和当前小区的传输也是不 同步的，因此，选择一个其它小区开始接收在RRC连接态就在接收的业务，会造成业务接收上的中断，影响用户的体验。因此，如何从RRC连接态进入RRC不活跃态时能够保证业务接收的连续性是一个要解决的问题。
针对以上所述问题，本申请提供了一种解决方案。
需要说明的是，在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。本申请所提出的方法也可以用于解决通信中的其它问题，例如包括需要在RRC不活跃态使用单播无线承载接收，尤其是要保证从RRC连接态到RRC不活跃态时使用单播无线承载连续接收的场景。
