Abstract: A method and/or an apparatus for cancelling sidelink (SL) channel state information (CSI) reporting in a wireless communication system is provided. A first wireless device establishes a first PC5-Radio Resource Control (RRC) connection with a second wireless device and a second PC5-RRC connection with a third wireless device. A first wireless device triggers the first SL CSI reporting for a first pair of a Source ID for the first wireless device and a Destination ID for the second wireless device, wherein the first pair is corresponding to the first PC5-RRC connection. A first wireless device generates a MAC CE for the first SL CSI reporting. A first wireless device cancels the triggered first SL CSI reporting for the first pair.

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 of operating a first user equipment (UE) in a wireless communication system includes receiving information related to a sidelink bandwidth part (BWP) by the first UE, establishing a plurality of unicast links by the first UE, transmitting a sidelink signal in the sidelink BWP on a first unicast link among the plurality of unicast link, and releasing a second unicast link for which radio link failure (RLF) has been declared among the plurality of unicast links, based on the RLF and a PC5 link identifier (ID) by the first UE. The PC5 link ID is used to identify the second unicast link for which the RLF has been declared among the plurality of unicast links.

Abstract: A method for performing wireless communication by a first device and an apparatus for supporting same are provided. The method may comprise: receiving, from a base station, information related to a first sidelink (SL) resource and information related to a first physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control (MAC) packet data unit (PDU) by using the first SL resource, wherein the MAC PDU includes a packet related to a logical channel for which hybrid automatic repeat request (HARQ) feedback is disabled, and wherein the MAC PDU includes no packet related to a logical channel for which HARQ feedback is enabled; determining that retransmission of the MAC PDU is required; and transmitting, to the base station, NACK information by using the first PUCCH resource based on no SL grant available for retransmission of the MAC PDU.

Abstract: A method and apparatus for control SL BSR based on different direct links in sidelink communication system is provided. A first wireless device establishes a sidelink between a second wireless device. A first wireless device triggers a sidelink (SL) buffer status report (BSR) based on data available for transmission via the sidelink. A first wireless device detects a failure on the sidelink. A first wireless device cancels the triggered SL BSR based on the failure on the sidelink.

Abstract: The present disclosure relates to logical channel prioritization (LCP) in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: creating a media access control (MAC) protocol data unit (PDU); and transmitting the MAC PDU to a second wireless device, wherein the MAC PDU includes at least one of data from sidelink control channel (SCCH), a MAC control element (CE) for sidelink (SL) feedback information, or data from sidelink transmission channel (STCH) according to a logical channel prioritization (LCP), wherein the data from SCCH including one or more PC5-signalling (PC5-S) messages has a higher priority to be included in the MAC PDU than the MAC CE for SL feedback information, and wherein the MAC CE for SL feedback information has a higher priority to be included in the MAC PDU than the data from STCH.
