层二中继通信中的连接状态的说明如下：
中继终端仅在连接管理连接态(CM-CONNECTED)/无线资源控制连接态(RRC Connected)下才能为远端终端中继数据或者信令；
如果中继终端在连接管理空闲态(CM_IDLE)下收到远端终端的用于中继通信的PC5连接建立请求，则中继终端应触发服务请求过程进入CM-CONNECTED态；
远端终端如果是CM-CONNECTED态，则中继终端应也是CM-CONNECTED态；
连接在中继终端上的所有远端终端进入CM-IDLE态，则中继终端可能进入CM-IDLE态；
当远端终端是CM-IDLE态或者CM-CONNECTED态，中继终端和远端终端保持PC5连接。
注册和连接管理：
对于层二中继通信，远端终端和中继终端属于相同的注册公用陆地移动网(Public Land Mobile Network，PLMN)或者等效PLMN(Equivalent Public Land Mobile Network，ePLMN)。
一般地，当UE注册完成后，网络会给UE发送一个注册区域，当UE移动出所述注册区域，UE应发起移动注册更新过程，网络侧分配一个新的注册区域给UE。
