Method and apparatus for configuring sidelink discontinuous reception in a wireless communication system

Abstract

A method and device are disclosed for a User Equipment (UE) to configure sidelink discontinuous reception (DRX) for sidelink groupcast communication associated with a group are disclosed. In one embodiment, the method includes the UE applying a sidelink DRX configuration for the sidelink groupcast communication associated with the group, wherein the sidelink DRX configuration comprises at least one of an on-duration timer length used for determining an on-duration for each sidelink DRX cycle and/or a cycle length used for determining a length of each sidelink DRX cycle. The method further includes the UE deriving or determining a time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle based on at least an identifier associated with the group. The method also includes the UE monitoring a sidelink control channel, associated with the group, based on the sidelink DRX configuration and the time to start of on-duration for each sidelink DRX cycle or start of each sidelink DRX cycle.
