副链路组播通信的配置方法和终端
相关申请的交叉引用
本申请主张在2019年2月18日在中国提交的中国专利申请号No.201910120312.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及无线通信技术领域，尤其涉及一种副链路组播通信的配置方法和终端。
背景技术
下面简单介绍与副链路(sidelink，或译为侧链路，边链路等)相关的一些内容。
1、Sidelink介绍
长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持sidelink，用于终端用户设备(User Equipment，UE)之间不通过网络设备直接进行数据传输。请参考图1，图1为相关技术中的LTE中上行(Uplink)、下行(Downlink)和sidelink通信链路的示例图。从图1中可以看出，终端可以通过上行和下行链路与网络设备通信，也可以通过sidelink链路直接与其他终端通信。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service，QoS)需求的高级V2X业务将通过NR sidelink支持。
5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，但目前版本的NR系统只支持基站与终端间的接口，尚不支持终端之间直接通信的Sidelink接口。
2、Sidelink的传输形式
目前的sidelink传输主要包括广播(broadcast)，组播(groupcast)和单播(unicast)几种传输形式。单播顾名思义就是一对一(one to one)的传输。组播为一对多(one to many)的传输。广播也是one to many的传输，但是广播并没有UE属于同一个组的概念。
在sidelink组播通信中，当需要向组播组内的组成员发送接入层(Access Stratum，AS)的配置信息时，如果无法确定配置是否成功，会影响资源分配的可靠性。
