工作在mode 2下的UE始终在做资源感知，在数据包到达时，UE会根据数据包到达之前的一段时间内感知到的候选资源，在候选资源中随机选择此次传输和后续多此传输的资源，并在第一次传输的控制信息(SCI)中为后面的重传或者周期性传输预留资源。从而完成发送用户设备(TX UE)和接收用户设备(RX UE)之间的直连通信。因此，可以将UE之间协作通信的方式可以作为mode 2的一种增强，即：TX UE在在辅助UE的协助下来完成V2X通信，辅助UE既可以是RX UE，也可以是非本通信链路UE。图1为本申请实施例提供的一种辅助设备的确定***的结构示意图，如图1所示，该***包括TX UE 1、辅助UE 2和RX UE 3。其中，TX UE 1分别与辅助UE 2和RX UE 3通信连接。本申请实施例中，TX UE 1为控制信息的接收设备，辅助UE 2为控制信息的发送设备。
