CELL (RE)SELECTION AND SIDELINK RELAY (RE)SELECTION PROCEDURES

WIPO Patent Application WO/2022/016495

A1

Disclosed are techniques for wireless communication. In an aspect, a remote user equipment (UE) initiates a cell selection procedure, initiates, in response to failure of the cell selection procedure, a relay selection procedure, and establishes, in response to discovering a relay UE during the relay selection procedure that is available to provide one or more UE-to-network relay services to the remote UE, a sidelink with the relay UE. In another aspect, a remote UE establishes a first sidelink with a first relay UE to obtain one or more UE-to-network relay services from the first relay UE, performs a relay discovery procedure to determine whether at least one second relay UE is available for relay reselection, and initiates, based on the at least one second relay UE being available for relay reselection, a relay reselection procedure.
