Document Type and Number:

WIPO Patent Application WO/2016/183710

Kind Code:

A1

Abstract:

Disclosed are a method and apparatus for relay selection in device-to-device communications. The method comprises: a relay selection device determines link quality of a first link of each candidate relay UE in a candidate relay UE list, the candidate relay UE list comprising at least one candidate relay UE, and the first link of each candidate relay UE being a radio link between each candidate relay UE and a base station; and determine a target relay UE in the candidate relay UE list according to the link quality of the first link of each candidate relay UE in the candidate relay UE list, the target relay UE being used for relaying data transmitted between a first UE and the base station. By means of the method and apparatus for relay selection in device-to-device communications disclosed in the present invention, a proper relay UE can be selected for a first UE.
