    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: Provided is a method for a user device in a wireless communication system according to an aspect of the present disclosure in which: allocation information relating to a plurality of bandwidth parts (BWPs) is received, wherein the plurality of BWPs comprise a first BWP and a plurality of second BWPs comprised in the first BWP; a sidelink signal is transmitted on the first BWP on the basis of the activation of the first BWP; and the sidelink signal is transmitted on at least one second BWP on the basis of the activation of the at least one second BWP among the plurality of second BWPs. The allocation information comprises: the start point of the first BWP and the plurality of second BWPs; the size of the first BWP and the plurality of second BWPs; and the gap among the plurality of second BWPs. Each of the plurality of second BWPs is allocated within the first BWP from the start point in the gap unit on a frequency domain.

    Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: establishing a PC5 RRC connection with a second device; transmitting, to the second device, a first SCI through a PSCCH; transmitting, to the second device, a second SCI and data through a PSSCH related to the PSCCH; determining a PSFCH resource based on an index of a subchannel and a slot related to the PSSCH; based on failure to receive a SL HARQ feedback for the data from the second device based on the PSFCH resource, detecting an RLF for the PC5 RRC connection between the first device and the second device; and performing reselection for the relay device based on detecting the RLF for the PC5 RRC connection.
