1. A method for a first base station, comprising:
receiving a first information of multiple candidate relay User Equipments (UEs) from a remote UE;
sending the first information of multiple candidate relay UEs or a second information of multiple candidate relay UEs to a second base station for the second base station to select a target relay UE out of the multiple candidate relay UEs, wherein the second information of multiple candidate relay UEs is derived from the first information of multiple candidate relay UEs;
receiving a Radio Resource Control (RRC) reconfiguration message from the second base station for the remote UE performing direct-to-indirect communication path switching, wherein the RRC reconfiguration message includes information identifying the target relay UE for the direct-to-indirect communication path switching and includes a set of configurations for the direct-to-indirect communication path switching; and
sending the RRC reconfiguration message to the remote UE for performing the direct-to-indirect communication path switching.
