1. A method performed by a transmitting (TX) wireless/transmit receive unit (WTRU) to conduct discontinuous transmission on sidelink (SL) to a receiving (RX) WTRU, the method comprising:
receiving a plurality of discontinuous reception (DRX) configurations from a network entity, each DRX configuration associated with one or more sets of Quality of Service (QOS) parameters, each DRX configuration including a respective periodicity and a respective active time duration, the plurality of DRX configurations associated with one or more RX WTRUs, the one or more RX WTRUs being associated with a destination layer-2 identifier (ID), the destination layer-2 ID being associated with multiple DRX configurations of the plurality of DRX configurations;
determining a periodicity and an active time duration for a DRX cycle associated with the destination layer-2 ID based on the multiple DRX configurations associated with the destination layer-2 ID, wherein the periodicity and the active time duration are associated with a transmission window for the destination layer-2 ID; and
performing a first SL transmission associated with the destination layer-2 ID, wherein the first SL transmission occurs within the transmission window that is associated with the periodicity and the active time duration that were determined based on the multiple DRX configurations associated with the destination layer-2 ID.
