    Abstract: Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. For example, the first device may obtain a sidelink discontinuous reception configuration including information related to an SL DRX timer. For example, the first device may obtain information related to a scheduling request configuration for a SL channel state information reporting medium access control control element (CE). For example, the first device may determine the SR configuration for the SL CSI reporting MAC CE as an SR configuration for an SL DRX command MAC CE. For example, the first device may transmit, to the base station, an SR for requesting a resource for the SL DRX command MAC CE, based on the SR configuration for the SL CSI reporting MAC CE. For example, the first device may transmit, to the second device, the SL DRX command MAC CE, based on the resource.

    Abstract: The present disclosure relates to transmission prioritization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: configuring a threshold; creating a media access control (MAC) protocol data unit (MAC PDU) for sidelink comprising a MAC control element (CE); setting a priority value to the MAC CE; identifying a transmission of the MAC PDU for sidelink and an uplink transmission to be performed; determining that the transmission of the MAC PDU for sidelink and the uplink transmission are not able to be performed simultaneously; determining that the priority value of the MAC CE is lower than the threshold; prioritizing the transmission of the MAC PDU for sidelink over the uplink transmission; and performing the transmission of the MAC PDU for sidelink that is prioritized over the UL transmission.

    Abstract: A method of operating a first user equipment (UE) in a wireless communication system is disclosed. The method includes performing an access stratum (AS) configuration procedure with a second UE by the first UE, and transmitting a radio resource control (RRC) message to a base station (BS) based on failure of the AS configuration procedure by the first UE. The RRC message includes information about a destination identifier (ID) of a unicast link related to the failure of the AS configuration procedure.

    Abstract: A method and apparatus for clearing a part of a sidelink grant in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission to a second wireless device, and receives, from a third wireless device, sidelink control information (SCI) which schedules sidelink transmission from the third wireless device. When (i) priority of the sidelink transmission from the third wireless device is higher than priority of the sidelink transmission to the second wireless device, (ii) reference signal received power (RSRP) measurement for the received SCI is higher than a threshold, and (iii) a resource for the sidelink transmission from the third wireless device overlaps with the first resource, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.

    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.
