1. A User Equipment (UE), comprising:
a wireless transceiver, configured to perform wireless transmission and reception to and from one or more peer UEs; and
a controller, configured to determine one or more Sidelink (SL) Discontinuous Reception (DRX) configurations, and apply the one or more SL DRX configurations to enable an SL DRX operation for SL communications with the peer UEs via the wireless transceiver, each SL DRX configuration including at least one of an SL DRX cycle, an SL DRX-ON duration, an SL DRX start offset, and an SL DRX inactivity timer;
wherein the UE is configured to perform the SL DRX operation to monitor a Sidelink Control Information (SCI) during an SL active time, and the SL active time is determined according to the corresponding one or more SL DRX configurations,
the UE maintains separate SL active times for different SL DRX configurations when multiple SL DRX configurations corresponding to the multiple peer UEs for unicast, groupcast, or broadcast communication are applied.
