1. A method performed by a User Equipment (UE) for Sidelink (SL) communication, the method comprising:
performing an SL transmission based on a first set of timers configured for controlling SL Discontinuous Transmission (DTX) behaviors of the UE;
performing an SL reception based on a second set of timers configured for the controlling SL Discontinuous Reception (DRX) behaviors of the UE;
determining a DRX state according to the first set of timers;
determining a state of a prohibitor for a UE group according to at least one Hybrid Automatic Repeat Request (HARQ)-process-specific timer in the first set of timers;
performing the SL transmission to the UE group after determining that the DRX state is an active state and the prohibitor is in an allowed state, wherein the prohibitor is in the allowed state when at least one of the at least one HARQ-process-specific timer is running; and
refraining from performing the SL transmission to the UE group in a case that the prohibitor is in a prohibited state, wherein the prohibitor is in the prohibited state when none of the at least one HARQ-process-specific timer is running, wherein at least one first timer value of the first set of timers is independently configured relative to at least one second timer value of the second set of timers.
