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

Abstract

A method and device are disclosed from the perspective of a first User Equipment (UE) to support Sidelink (SL) Discontinuous Reception (DRX). In one embodiment, the method includes the first UE establishing a unicast link with a second UE. The method further includes the first UE receiving a SL DRX configuration associated with the second UE from the second UE. The method also includes the first UE transmitting the SL DRX configuration to a network node. In addition, the method includes the first UE receiving a sidelink grant from the network node, wherein the sidelink grant indicates sidelink resources. Furthermore, the method includes the first UE performing a sidelink transmission to the second UE based on the sidelink resources.
