Abstract: Provided is a method by which a first apparatus performs wireless communication and an apparatus for supporting the method. The method comprises the steps of: receiving, from a base station, information related to a sidelink (SL) bandwidth part (BWP); receiving, from the base station, information related to an uplink (UL) BWP; receiving, from the base station, information related to an SL resource and information related to a UL resource for reporting a hybrid automatic repeat request (HARQ) feedback; transmitting, on the basis of the SL resource within the SL BWP, data in which the HARQ feedback has been disabled to a second apparatus through a physical sidelink shared channel (PSSCH); generating an ACK related to the transmission of the data in which the HARQ feedback has been disabled; and transmitting, to the base station, the ACK on the basis of the UL resource within the UL BWP.

Abstract: Provided are a method by which a first device performs wireless communication, and a device for supporting same are provided. The method can comprise the steps of: receiving information related to a sidelink (SL) bandwidth part (BWP); receiving, from a network, SL synchronization priority order information set through global navigation satellite systems (GNSS)-based synchronization; receiving, from the network, information for indicating whether selection of a base station (BS)-related synchronization reference is disabled; detecting, on the basis of the information for indicating that the selection of the base station-related synchronization reference is disabled, a synchronization signal transmitted through the SL BWP by a GNSS-related synchronization reference or other UEs; and performing synchronization with respect to the GNSS-related synchronization reference or one synchronization reference from among the other UEs on the basis of the synchronization signal.

Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: receiving a plurality of sidelink-synchronization signal blocks (S-SSBs) from a plurality of synchronization sources, wherein each of the plurality of S-SSBs includes a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH); selecting any one of the plurality of synchronization sources on the basis of a reference signal received power (RSRP) associated with each of the plurality of S-SSBs and a sidelink synchronization signal (SLSS) ID associated with each of the plurality of S-SSBs; performing synchronization on the basis of the S-SSB associated with the selected synchronization source; and transmitting a PSCCH or PSSCH to a second device on the basis of the synchronization. For example, the SLSS ID associated with each of the plurality of S-SSBs may be a criterion for selecting any one of the plurality of synchronization sources, on the basis of the fact that a RSRP value associated with each of the plurality of S-SSBs is greater than or equal to a minimum RSRP threshold value.
