本发明专利技术实施例提供一种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。本发明专利技术适用于无线通信领域。

A data transmission method, equipment and system for D2D

The embodiment of the invention provides a data transmission method, equipment and system of D2D, so as to solve at least the problem of how to find a UE in the network coverage as relay UE in the existing technology, and transmit the information of UE outside the network coverage to the base station. The method includes: a first message to the source UE N candidate UE sent the first message to indicate the source of UE data needs to be transmitted to the base station, the base station for the source UE network coverage of UE n, a candidate UE for the base station network covering a range of UE; source UE receives n second message from n the candidate UE in which each candidate UE N candidate in UE to the source UE sends a second message, the second message includes status information for each candidate UE user ID and / or each candidate UE source; UE according to the state information of each candidate UE user ID and / or each candidate UE information, determine the relay UE from the N candidate UE, and the data is transmitted to a base station through the relay UE. The invention is suitable for the field of wireless communication.
