Abstract

The embodiment of the invention provides a relay UE reselection method and device, communication equipment and a storage medium. The relay UE reselection method comprises the steps that in response toconfiguration failure of a direct connection link SL between far-end UE and relay UE, the far-end UE reselects the relay UE based on a limited reselection condition; that is to say, the remote UE canreselect the relay UE according to the restricted reselection condition. Thus, compared with the method for reselecting the relay UE by adopting any mode (such as not according to the limited reselection condition), the method provided by the embodiment of the invention has the advantages that the probability of reselecting the relay UE with configuration failure before reselection can be greatlyreduced; therefore, the probability of connection failure of the direct connection link again is greatly reduced, namely, the connection success rate of the direct connection link between the remoteUE and the reselected relay UE is improved.

Description

technical field [0001] The present disclosure relates to the field of wireless communication but is not limited to the field of wireless communication, and in particular to a reselection method, device, communication device and storage medium for a relay UE. Background technique [0002] In related technologies, in order to support direct communication between user equipment (User Equipment, UE), a direct link (SideLink) communication manner is introduced. According to the corresponding relationship between sending and receiving UEs, three transmission modes of unicast, multicast and broadcast are supported on the direct link. [0003] A UE may not be directly connected to the base station, but to achieve connection and communication with the base station through the relay of another UE; among them, the UE connected to the base station is called a remote UE (remote UE), and the UE that provides the relay function is a remote UE. Relay UE (relayUE). The remote UE communicat...
