Abstract: A method for operating a first device (100) in a wireless communication system is proposed. The method may comprise the steps of: generating uplink (UL) data; on the basis of sidelink (SL) discontinuous reception (DRX) configuration-related on/off switching of a SL radio frequency (RF) module, which is performed at a first time point, determining that transmission of the UL data does not occur at the first time point; and on the basis of the determination that transmission of the UL data does not occur at the first time point and a priority value, which is related to the UL data and is smaller than a threshold value, changing a time point, at which the on/off switching of the SL RF module is performed, from the first time point to a second time point.

Abstract: Provided are a method for performing wireless communication by a first device and a device supporting same. The method may comprise the steps of: configuring information on a first sidelink (SL) priority threshold value associated with a first radio access technology (RAT); configuring information on a second SL priority threshold value associated with a second RAT; configuring information on a third SL priority threshold value; and on the basis that uplink (UL) transmission and SL transmission overlap each other in a time domain, performing prioritization for the UL transmission and the SL transmission. For example, on the basis that RATs of the UL transmission and the SL transmission are different, the prioritization for the UL transmission and the SL transmission may be performed on the basis of the third SL priority threshold value.

Abstract: An embodiment is a sidelink-related operation method of a transmitting (TX) user equipment (UE) in a wireless communication system, the method comprising the steps in which the TX UE: receives a configuration of a round trip time (RTT) timer and a retransmission timer from a base station; transmits a physical sidelink shared channel (PSSCH) to a receiving UE (RX UE); receives a physical sidelink feedback channel (PSFCH) related to the PSSCH from the RX UE; starts the RTT timer; and starts the retransmission timer after the RTT timer ends, wherein the retransmission timer is started on the basis that a PSFCH-related PUCCH transmission to the base station is dropped.
