Abstract: A method according to an embodiment of the present disclosure includes receiving SCI from a first UE and receiving data from the first UE based on the SCI. The SCI is received through monitoring performed in an active time based on a configuration related to SL DRX. The active time includes a time duration in which a pre-configured SL DRX timer is running. The time duration in which the pre-configured SL DRX timer is running includes one or more slots based on a predefined value. A slot of a resource pool other than a predefined resource pool among slots determined by physical slot indexes related to the predefined value is excluded from the one or more slots.

Abstract: Proposed are a method by which a first device performs wireless communication and a device supporting same. For example, the first device can determine at least one first candidate resource within the selection window on the basis of sensing. For example, the first device can select one or more SL resources from among the at least one first candidate resource. For example, the first device can reset the first SL DRX configuration to a second SL DRX configuration including information related to a second active time of the second device. For example, the first device can trigger resource reselection on the basis of the one or more SL resources not being included in the second active time of the second device.
