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.

Abstract: Provided are a method by which a first apparatus configures a bandwidth part (BWP) and an apparatus for supporting same. The method may comprise the steps of: configuring a first BWP related to communication between the first apparatus and a base station; and configuring a second BWP related to sidelink communication between the first apparatus and a second apparatus. Here, numerology of the first BWP and numerology of the second BWP may be the same.

Abstract: Provided is a method of operating a transmitting user equipment (UE) in a wireless communication system. The method includes receiving a first radio resource control (RRC) configuration-related message by the transmitting UE (Tx UE), and transmitting a message to a receiving UE by the Tx UE. The first RRC configuration-related message includes sidelink hybrid automatic repeat request (HARQ) enable or HARQ disable configuration information.

Abstract: A method and apparatus for confirmation of multiple configured grants for sidelink in a wireless communication system is provided. A wireless device receives activation command or deactivation command on Physical Downlink Control Channel (PDCCH) for at least one of the multiple configured grants. A wireless device receives transmits, to the network, a confirmation Media Access Control (MAC) Control Element (CE). The confirmation MAC CE includes one or more fields in a bit group of which size is equal to number of the multiple configured grants. Each field in the bit group is set to (i) zero to indicate deactivation for each of the multiple configured grants or (ii) 1 to indicate activation for each of the multiple configured grants. Each field in the confirmation MAC CE except the bit group is ignored.
