    Abstract: A method for a first device to perform wireless communication and a device supporting same. The method may include: receiving, from the base station through a second PDCCH, a second DCI including information related to a second SL resource and information related to a second PUCCH resource; transmitting a first physical sidelink shared channel (PSSCH) based on the first SL resource; and transmitting, to the base station through the second PUCCH resource, first hybrid automatic repeat request (HARQ) feedback information related to the first PSSCH and second HARQ feedback information related to the second PSSCH, based on a slot including the first PUCCH resource being same as a slot including the second PUCCH resource, wherein the second DCI is a last DCI among a plurality of DCIs including information related to the slot for PUCCH transmission.

    Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: receiving a radio resource control (RRC) message including information related to configured grant (CG) from a base station, wherein the information related to the CG include information for an offset related to the CG and information for a period related to the CG; based on at least one resource pool being configured for the first apparatus, performing sidelink transmission to a second apparatus based on sidelink resources determined from among candidate resources allocated by the CG in the at least one resource pool. For example, the sidelink resources determined from among the candidate resources allocated by the CG are located after the offset related to the CG from the closest sidelink slot after the time when the system frame number (SFN) is zero. For example, the sidelink resources from among the candidate resources allocated by the CG are repeated with the period related to the CG.

    Abstract: The present invention relates to a method for performing positioning in a cellular-vehicle to everything (C-V2X) system, and a device therefor. A method for performing positioning in a terminal mounted on a positioning vehicle in a C-V2X communication system according to one aspect may comprise the steps of: measuring a time of flight (ToF) by performing road side unit (RSU) and round trip time (RTT) ranging; determining a positioning mode, wherein the positioning mode includes a self-positioning mode and a cooperative positioning mode; measuring the relative positions of surrounding vehicles by using a sensor provided in the positioning vehicle on the basis of the determined positioning mode being the cooperative positioning mode, and storing first positioning measurement information corresponding to the measured relative positions; selecting a surrounding vehicle on which to perform cooperative positioning; transmitting the first positioning measurement information to the selected surrounding vehicle; receiving second positioning measurement information from the selected surrounding vehicle; and determining the current location of the positioning vehicle on the basis of the first and second positioning measurement information.
