背景技术
新空口(New Radio，NR)中，副链路(Sidelink，SL)通信系统中的中继(Relay)技术，是在基站与终端之间增加一个或多个中继节点，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。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。
以两跳中继为例，无线中继就是将一个基站至终端的链路分割为基站至中继站和中继站至终端两个链路，从而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。其中，relay一端连接用户终端(User Equipment，UE)，一端连接网络侧。跟relay连接的UE为远端UE(remote UE)。
