Abstract: A method performed by a second terminal supporting SL DRX in a wireless communication system, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, configuration information related to a resource pool for sidelink communication; receiving an SCI from a first terminal; and receiving, on the basis of the SCI, SL data from the first terminal. On the basis of an L2 destination ID associated with the SL data being associated with a plurality of QoS profiles, a resource pool to which an operation related to SL DRX is applied is determined, from among resource pools based on the configuration information, on the basis of a QoS profile associated with the SL data among the plurality of QoS profiles. SL DRX configuration mapped to the QoS profile associated with the SL data is applied to the determined resource pool.
