Abstract: A method and apparatus for allocation of lower identifier (ID) and upper identifier (ID) for sidelink transmission in a wireless communication system is provided. A first wireless device (e.g., receiving user equipment (UE)) receives, via upper layer signaling from a second wireless device (e.g., transmitting UE), a lower ID associated with an upper ID and monitors sidelink control information (SCI) based on the lower ID and the upper ID. The first wireless device receives, from the second wireless device, a data unit scheduled by the SCI.

Abstract: Proposed is an operating method for a first device (100) in a wireless communication system. The method may comprise the steps of: transmitting a physical sidelink control channel (PSCCH) to a second device (200); transmitting, to the second device (200), a physical sidelink shared channel (PSSCH) on the basis of the PSCCH; determining a physical sidelink feedback channel (PSFCH) resource related to the PSSCH on the basis of an index of a slot related to the PSSCH and an index of a subchannel; and declaring sidelink (SL) radio link failure (RLF) for a connection between the first device (100) and the second device (200), on the basis that a discontinuous transmission (DTX) counter reaches a maximum DTX-related threshold.
