具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
UE通过物理副链路控制信道(Physical Sidelink Control Channel,PSCCH)发送副链路控制信息(Sidelink Control Information,SCI),调度物理副链路共享信道(Physical Sidelink Shared Channel,PSSCH)的传输以发送数据。该传输是以广播形式进行的,接收端并不向发送端反馈接收是否成功。
LTE sidelink设计支持两种资源分配模式,分别是调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式。前者由网络侧设备控制并为每个UE分配资源,后者由UE自主选择资源。
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,其他高级V2X业务将通过新空口(New Radio,NR)sidelink支持。
NR系统的V2X研究目前刚刚开始,目前各公司倾向于在NR系统中,支持多种传输方式,包括单播、组播和广播。单播顾名思义就是one to one的传输,组播为one to many的传输。
目前V2X传输的时候有“资源池”的概念,资源池由网络侧发送或预配置,资源池中会包含传输所用的资源和很多传输相关的参数,包括资源池第一个子帧的偏移值、资源池对应的比特位图(bitmap)、是否会在相邻资源块(Resource Block,RB)传输PSCCH和PSSCH、子信道的数量和每个子信道的大小以及子信道对应的最低RB索引值、PSCCH pool对应的最低RB索引值、信道忙碌比率(Channel Busy Rate,CBR)测量的副链路-接收的信号强度指示(Sidelink Received Signal Strength Indication,S-RSSI)门限、区域标识等等。
相关技术中,UE在建立副链路连接时,所使用的资源可能与其他业务的资源冲撞,导致UE不能快速地建立副链路连接。
为了解决这一问题,本公开提供一种副链路连接建立、资源分配方法、终端及网络侧设备,专门定义一类单独的资源,来进行副链路连接建立相关消息的传输,以便UE能够快速地建立副链路连接避免资源冲撞。另外,也可以将此类消息和UE的业务消息在同一个资源池中发送,但是赋予他们不同的优先级或者QoS要求。
