Abstract: A method and apparatus for indicating sidelink (SL) radio link failure (RLF) in a wireless communication system is provided. A first wireless device may initialize the counter to zero upon 1) establishing the PC5-RRC connection with the second wireless device, or 2) configuring or reconfiguring the maximum number of the counter. A first wireless device may increase the counter based on no reception of any acknowledgement to the transmission of the MAC PDU. A first wireless device may indicate Sidelink (SL) Radio Link Failure (RLF) for the PC5-RRC connection based on that the counter reaches the maximum number of the counter.

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.
