Abstract

本发明实施例提供一种D2D的数据传输方法、设备及系统，以至少解决现有技术中如何寻找一个网络覆盖内的UE作为中继UE，将一个在网络覆盖外的UE的信息传输给基站的问题。方法包括：源UE向n个候选UE发送第一消息，第一消息用于指示源UE有数据需要传输给基站，其中，源UE为基站网络覆盖范围外的UE，n个候选UE为基站网络覆盖范围内的UE；源UE接收来自n个候选UE的n个第二消息，其中，n个候选UE中的每个候选UE向源UE发送一个第二消息，第二消息包括每个候选UE的用户标识和/或每个候选UE的状态信息；源UE根据每个候选UE的用户标识和/或每个候选UE的状态信息，从n个候选UE中确定中继UE，并通过中继UE将数据传输给基站。本发明适用于无线通信领域。
