    Abstract: An operating method for a first device (100) in a wireless communication system is presented. The method may comprise the steps of: transmitting an RA preamble to a base station (300); receiving, from the base station (300), a random access response (RAR) message related to the RA preamble; transmitting, to the base station (300), a physical uplink shared channel (PUSCH) as a response to the RAR message; receiving, from the base station (300), downlink control information (DCI) generated on the basis of a radio network temporary identifier (RNTI) related to the RA procedure, as a response to the PUSCH; determining overlapping between sidelink (SL) communication and physical uplink control channel (PUCCH) transmission related to the DCI; and transmitting a PUCCH to the base station (300) on the basis of the overlapping.

    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: Disclosed are a method and a device in which a terminal receives a signal by using at least one distributed antenna unit (DU) and a center antenna unit (CU) controlling the at least one distributed antenna unit in a wireless communication system supporting a sidelink according to various embodiments. Disclosed are a method and a device therefor, the method comprising the steps of: receiving a first signal and a second signal by using at least one DU; transferring first information, which is decoding information for the first signal, from the at least one DU to the CU through a first interface; and decoding the second signal on the basis of the first information by using the CU, wherein a feedback signal for the second signal is transmitted on the basis of a time gap configured for the second signal, and the time gap is configured in consideration of a time error or a time delay related to the first interface.

    Abstract: According to one embodiment of the present disclosure, a method by which a first device performs wireless communication is provided. The method comprises the steps of: determining a UL resource grid in a UL BWP of a carrier on the basis of a first SCS; determining an SL resource grid in an SL BWP of the carrier on the basis of a second SCS; and allowing UL transmission to a base station or SL transmission to a second device on the basis of the UL resource grid or the SL resource grid, wherein the SL BWP or the UL BWP can be deactivated on the basis of the first SCS and the second SCS being the same and the RB boundary of the UL resource grid and the RB boundary of the SL resource grid not matching.

    Abstract: A method and apparatus for resource allocation for sidelink configured grant is provided. A first wireless device receives, from a network, a cell specific Uplink (UL)-Downlink (DL) Time Division Duplex (TDD) configuration and considers that a first slot of a specific sidelink grant occurs in a logical slot determined based on a periodicity. The periodicity is determined based on a number of slots related to sidelink transmission, and the number of slots is determined based on the cell specific UL-DL TDD configuration.
