    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.
