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.
