Abstract: Proposed is an operation method of a first device (100) in a wireless communication system. The method may comprise the steps of: establishing a first PC5-radio resource control (RRC) connection with a second device (200); establishing a second PC5-RRC connection with a third device (300); starting a first sidelink (SL) discontinuous reception (DRX) timer related to an active time of a first SL DRX configuration related to the first PC5-RRC connection; starting a second SL DRX timer related to an active time of a second SL DRX configuration related to the second PC5-RRC connection; receiving a medium access control (MAC) control element (CE) related to the first SL DRX configuration from the second device (200); and stopping the first SL DRX timer on the basis of the MAC CE.
