Abstract: Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: establishing a connection with a second device; and reselecting a cell on the basis that the first device is in a radio resource control (RRC) IDLE state or an RRC INACTIVE state. For example, a priority related to cell reselection can be set such that a cell related to a new radio (NR) has a high priority. For example, cell reselection can be performed first on the cell related to the NR on the basis of the priority related to cell reselection.

Abstract: Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. For example, the first device may obtain a sidelink discontinuous reception configuration including information related to an SL DRX timer. For example, the first device may obtain information related to a scheduling request configuration for a SL channel state information reporting medium access control control element (CE). For example, the first device may determine the SR configuration for the SL CSI reporting MAC CE as an SR configuration for an SL DRX command MAC CE. For example, the first device may transmit, to the base station, an SR for requesting a resource for the SL DRX command MAC CE, based on the SR configuration for the SL CSI reporting MAC CE. For example, the first device may transmit, to the second device, the SL DRX command MAC CE, based on the resource.

Abstract: An embodiment is a method for operating a relay UE related to a sidelink relay in a wireless communication system, the method comprising steps for the relay UE to: deliver a sidelink grant request including a Packet Delay Budget (PDB) of a remote UE to a base station; and receive an uplink grant configuration and a sidelink grant configuration from the base station as a response to the sidelink grant request, wherein only information related to the sidelink grant configuration among the uplink grant configuration and the sidelink grant configuration is delivered by the relay UE to the remote UE. The uplink grant configuration is used for delivering packets of the remote UE to the base station, wherein the packets are packets received through a resource indicated by the sidelink grant configuration, and the resource indicated by the sidelink grant configuration and a resource indicated by the uplink grant configuration both satisfy the PDB.
