Abstract: A method for performing, by a first device, wireless communication and an apparatus for supporting same are provided. The method includes: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting, to the second device, a hybrid automatic repeat request (HARQ) feedback on the PSFCH resource. Here, at least one subchannel for the PSSCH is associated with at least one first PSFCH resource including at least one second PSFCH resource, each second PSFCH resource included in the at least one first PSFCH resource is associated with each slot on the at least one subchannel, and the PSFCH resource may be determined on the basis of information related to the at least one subchannel for the PSSCH, information related to at least one slot for the PSSCH, and a source ID of the second device.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes transmitting a physical sidelink shared channel (PSSCH) to a second UE by the first UE, and transmitting, to a base station (BS), feedback information based on a physical sidelink feedback channel (PSFCH) for the PSSCH on a physical uplink control channel (PUCCH) by the first UE. A transmission timing of the PUCCH is determined based on information about the number of slots from the PSFCH to the PUCCH.

Abstract: A method for performing wireless communication by a first device includes: receiving information related to a time division duplex (TDD) slot configuration, transmitting, to a second device, a sidelink-synchronization signal block (S-SSB), the S-SSB including a sidelink primary synchronization signal, a sidelink secondary synchronization signal, and a physical sidelink broadcast channel, and transmitting, to the second device, a physical sidelink shared channel based on the information related to the TDD slot configuration. Candidate resources to which a bitmap related to a sidelink resource pool is applied (i) are configured based on the information related to the TDD slot configuration and (ii) include one or more slots. Configuration information related to a sidelink symbol included in each of the one or more slots is received, the configuration information including information related to a position of the sidelink symbol configured to be the same for the candidate resources.

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.
