    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 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.
