1. A method for performing wireless communication by a first device, the method comprising:
establishing a PC5-RRC (radio resource control) connection with a second device;
obtaining an SL DRX configuration including information related to an SL (sidelink) DRX (discontinuous) cycle and information related to a timer for active time, wherein the timer for active time includes at least one of an SL DRX on-duration timer or an SL DRX inactivity timer, and
wherein a time during which the SL DRX on-duration timer is running or a time during which the SL DRX inactivity timer is running is a time included in an active time of the second device;
triggering SL DRX command MAC (medium access control) CE (control element) reporting related to the PC5-RRC connection; and
canceling the triggered SL DRX command MAC CE reporting, based on an MAC reset for the PC5-RRC connection being requested,
wherein the SL DRX command MAC CE is information for stopping at least one of the SL DRX on-duration timer or the SL DRX inactivity time, and
wherein the SL DRX command MAC CE is information for keeping the second device from monitoring PSCCH (physical sidelink control channel) before a next SL DRX cycle.
