摘要： A method for performing wireless communication by a first device and a device supporting same are proposed. For example, the first device may acquire an SL DRX configuration including information related to an SL DRX timer for an active time and information related to an SL DRX cycle. For example, the SL DRX timer for the active time may include at least one of an SL DRX on-duration timer and an SL DRX inactivity timer. For example, at least one of a time in which the SL DRX onduration timer is running and a time in which the SL DRX inactivity timer is running may be included in the active time. For example, the first device may trigger an SR for requesting a first resource within a first SL DRX cycle. For example, the first device may trigger generation of an SL DRX command CE for stopping the SL DRX timer. For example, on the basis of the first resource being within an active time related to a second SL DRX cycle, the triggered SL DRX command MAC CE may be canceled.

摘要： Proposed are a method by which a first device performs wireless communication and a device supporting same. For example, the first device can obtain a first SL DRX configuration including information related to a first active time of a second device. For example, the first device can trigger resource selection. For example, the first device can determine a selection window on the basis of the triggering of the resource selection. 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.

摘要： 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.

摘要： Proposed are a method by which a first device carries out wireless communication, and an apparatus supporting same. The first device may establish a PC5-RRC connection with a second device. For example, the first device may acquire a DRX configuration including information related to a Uu DRX timer. For example, the Uu DRX timer may be at least one of a DRX HARQ RTT timer and a DRX retransmission timer. For example, a time during which the DRX retransmission timer is running may be a time included in an active time of the first device. For example, the first device may initiate the Uu DRX timer. For example, an SL-specific MAC reset for the PC5-RRC connection with the second device is requested, and the initiated Uu DRX timer may stop on the basis that the initiated Uu DRX timer is running. For example, the DRX HARQ RTT timer may indicate a minimum duration before an SL retransmission grant is expected by the first device. For example, the DRX retransmission timer may indicate a maximum duration until the SL retransmission grant is received by the first device.
