Abstract: A method of operating a first apparatus 100 in a wireless communication system is proposed. The method may include: receiving a value related to priority of first data and the first data from a second apparatus 200; determining data to be transmitted based on a first resource, by comparing a threshold related to relay communication and the value related to the priority of the first data; and transmitting the determined data to a base station 300.

Abstract: One embodiment provides a method for performing an operation for a first terminal in a wireless communication system, wherein: in an on-duration period, a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) is monitored; on the basis of reception of at least one sidelink traffic indication indicating that there is sidelink data to be transmitted from a second terminal, a physical sidelink shared channel (PSSCH) including second SCI is monitored; and on the basis of non-reception of at least one sidelink traffic indication indicating that there is sidelink data to be transmitted from the second terminal, the PSSCH including the second SCI is not monitored. The first UE communicates with at least one of another UE, a UE related to an autonomous driving vehicle, or a base station (BS), or a network.
