Abstract: A method and apparatus for periodic transmissions for a configured grant is provided. A first device operating in a wireless communication system transmits, to a second device, a media access control (MAC) protocol data unit (PDU) by using a first resource of a configured grant (CG) in a first period for which the first resource of the CG is associated with a HARQ process identifier (ID), and flushes a HARQ buffer associated with the HARQ process ID in a second period for which a second resource of the CG is associated with the HARQ process ID. Then, the first device ignores a retransmission resource associated with the HARQ process ID based on flushing the HARQ buffer.

Abstract: A method for a first device to perform wireless communication based on partial sensing and an apparatus supporting the same are provided. The method may comprise: triggering a resource selection procedure; determining a selection window within a packet delay budget (PDB) based on the triggering of the resource selection procedure; selecting Y candidate slots in the selection window; performing sensing within a contiguous partial sensing (CPS) window related to the Y candidate slots; and selecting a sidelink (SL) resource based on random selection within the selection window, based on the number of slots included in the CPS window which is less than a minimum number of slots, wherein Y is a positive integer.

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.
