技术领域

背景技术
无线通信系统中的中继(Relay)技术，就是在基站与终端设备之间增加了一个或多个中继设备，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达终端设备。
无线中继技术不仅可用于扩展小区覆盖，弥补小区覆盖盲点，同时也可通过空间资源复用提升小区容量。对于室内覆盖，Relay技术也可起到克服穿透损耗，提升室内覆盖质量的作用。
以较简单的一跳中继为例，无线中继就是将基站至终端设备的链路分割为基站至中继设备和中继设备至终端设备的两个链路，从而有机会将一个质量较差的链路替换为两个质量较好的链路，以获得更高的链路容量及更好的覆盖。
目前的终端到网络中继(UE-to-network relay)技术，即中继设备一端连接终端设备，一端连接网络侧设备。跟中继设备连接的终端设备，叫做远程(remote)终端设备。
目前远程终端设备发现旁链路发现参考信号接收功率(sidelinkdiscovery reference signal received power，SD-RSRP)的测量结果小于某个门限值时会进行中继重选。
