Abstract: In an embodiment of the present disclosure, there is provided a method of performing a radio resource control (RRC) related operation by a transmitter (TX) user equipment (UE) performing a sidelink (SL) discontinuous reception (DRX) operation in a wireless communication system. The method may include: receiving, by the TX UE, an SL DRX configuration from a base station; receiving, by the TX UE, a configured grant from the base station; performing, by the TX UE, SL transmission on a resource related to the configured grant during an active time based on the SL DRX configuration; performing, by the TX UE, an RRC connection related procedure to a network; and starting, by the TX UE, a timer for the RRC connection related procedure. The TX UE may perform transmission in an exceptional pool of the configured grant based on the SL DRX configuration after starting the timer. The SL DRX configuration may be maintained until expiration of the timer.
