Abstract: Performing a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, a method may include: transmitting message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein a power ramping counter is used to configure transmission power of message A, and the power ramping counter has a value which increases based on that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

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 clearing retransmission resources based on acknowledgement in a wireless communication system is provided. A first wireless device reserves multiple sets of resources for transmissions of multiple media access control (MAC) protocol data units (PDUs), transmits a first MAC PDU to a second wireless device using at least one resource from a first set of resources corresponding to the first MAC PDU among the multiple sets of resources, receives a positive acknowledgement for the first MAC PDU from the second wireless device, and clears remaining resources from the first set of resources corresponding to the first MAC PDU.

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.
