    Abstract: A first device receives information related to an absolute location of a positioning reference from the positioning reference; obtains a first PRS reception timing based on a positioning reference signal (PRS) received from the positioning reference; obtains a second PRS reception timing at which a second device receives the PRS from the positioning reference based on a phase difference value between first RSs received on first subcarriers from the second device; obtains a third PRS reception timing at which a third device receives the PRS from the positioning reference, based phase difference value between second RSs received on second subcarriers from the third device; estimates a relative location of the positioning reference based on the first PRS reception timing, the second PRS reception timing, and the third PRS reception timing; and obtains location information of the first device based on the absolute location and the relative location.

    Abstract: Proposed is an operation method of a first apparatus (100) in a wireless communication system. The method may comprise the steps of: selecting a first resource and a second resource in a selection window, on the basis of a sensing procedure; transmitting, through a first physical sidelink control channel (PSCCH) on the basis of the first resource, first sidelink control information (SCI) including information related to the second resource, to a second apparatus (200) for performing wireless communication on the basis of a sidelink (SL) discontinuous reception (DRX) configuration; transmitting, on the basis of the first resource, first SL data to the second apparatus 200 through a first physical sidelink shared channel (PSSCH) scheduled by the first SCI; triggering pre-emption related to the second resource; selecting a third resource after the second resource, on the basis of the triggered pre-emption, wherein the third resource before the second resource is not allowed to be selected; transmitting second SCI including information related to the third resource, to the second apparatus (200) through a second PSCCH; and transmitting second SL data to the second apparatus (200) through a second PSSCH scheduled by the second SCI.

    Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: selecting a first sidelink (SL) channel access priority class (CAPC) from among a plurality of SL CAPCs; selecting a destination related to a logical channel with a highest priority from among one or more logical channels related to the first SL CAPC; generating a medium access control (MAC) protocol data unit (PDU) based on at least one first logical channel related to the destination; transmitting, through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) and second SCI; and transmitting, through the PSSCH, the second SCI including an identifier (ID) related to the destination and the MAC PDU.

    Abstract: Proposed is an operation method of a first device (100) in a wireless communication system. The method may comprise the steps of: establishing a sidelink (SL) unicast link with a second device (200); transmitting first SL discontinuous reception (DRX) configuration information related to the SL unicast link to the second device (200); transmitting a physical sidelink control channel (PSCCH) to the second device (200) in an on-duration interval included in the first SL DRX configuration information; and transmitting a physical sidelink shared channel (PSSCH) to the second device (200) on the basis of the PSCCH in the on-duration interval.

    Abstract: Provided are a method for performing wireless communication by a first device, and a device for supporting same. The method may comprise: obtaining one or more sidelink (SL) Discontinuous Reception (DRX) configurations; obtaining a Quality of Service (QoS) profile and a transmission (TX) profile representing whether supporting SL DRX is compatible; selecting a SL DRX configuration related to the QoS profile from among the one or more SL DRX configurations, based on the TX profile representing compatibility of supporting SL DRX; and performing, with a second device, SL communication within an active time of the SL DRX configuration.

    Abstract: According to an embodiment of the present disclosure, provided is a method for performing wireless communication by a first apparatus. The method may comprise: obtaining sidelink (SL) discontinuous reception (DRX) configuration including information related to an active time of a second apparatus, receiving, from a base station, first information related to a first SL resource and second information related to an uplink (UL) resource, and transmitting, to the base station, SL hybrid automatic repeat request (HARQ) feedback information on the UL resource based on a time domain of the first SL resource not being included within the active time of the second apparatus. The SL HARQ feedback information may be SL HARQ acknowledge (ACK) information.
