Abstract: A method and apparatus for trigger and/or cancellation of sidelink scheduling request (SR) in a wireless communication system is provided. A wireless device determines that a physical uplink control channel (PUCCH) resource for transmission of a scheduling request (SR) overlaps with a sidelink (SL) resource for transmission of a SL media access control (MAC) protocol data unit (PDU). The wireless device transmits, to a network, the SR by using the PUCCH resource when a priority of the SR is higher than a priority of the SL MAC PDU.

Abstract: An embodiments relates to a method of operating a user equipment (UE) in a wireless communication system. The method includes: receiving, by the UE, downlink control information (DCI) from a base station (BS); and, determining, by the UE, a resource pool indicated by a resource pool index in the DCI from among a plurality of resource pools. Based on that resource pools related to New Radio (NR) sidelink discovery and resource pools related to NR sidelink communication transmission are configured together in the plurality of resource pools, the resource pool index indicates one resource pool among all resource pools included in the resource pools related to NR sidelink communication transmission and the resource pools related to NR sidelink discovery.

Abstract: A method of operating a first apparatus 100 in a wireless communication system is proposed. The method may comprise: determining a time duration in which a first active time and a second active time overlap; performing SL transmission or SL reception of a service related to a smaller priority value among a first priority value and a second priority value, within the overlapping time duration; and performing SL transmission or SL reception of a service related to a greater priority value among the first priority value and the second priority value, outside the overlapping time duration.

Abstract: Provided are a method by which a first device performs wireless communication, and a device supporting same. The method may comprise the steps of: receiving sidelink control information (SCI) including scheduling information for a physical sidelink shared channel (PSSCH) from a second device through a physical sidelink control channel (PSCCH), wherein the SCI includes information related to frequency resource allocation, information related to time resource allocation, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS); receiving first auxiliary information from the second device through the PSSCH; selecting at least one sidelink (SL) resource on the basis of at least one of at least one SCI or the first auxiliary information; performing resource reselection for the at least one SL resource; and transmitting an auxiliary information request to the second device on the basis of the resource reselection.

Abstract: A method and apparatus for activation and/or deactivation for a pool of resources is provided. A first device operating in a wireless communication system receives, from a network, a configuration of one or more resource pools for autonomous resource selection, selects a resource pool for a logical channel from among the one or more resource pools based on data being available in the logical channel, and transmits, to a second device, information on the selected resource pool.

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.
