Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: receiving, from a base station, information related to a configured grant (CG) for scheduling a sidelink resource; and on the basis of the information related to the CG, performing sidelink transmission to a second device on the basis of a sidelink resource allocated by the CG. For example, the information related to the CG may include information relating to an offset related to the CG and information relating to a period related to the CG. For example, the sidelink resource allocated by the CG may be positioned in a slot spaced apart by the offset related to the CG from the closest logical sidelink slot after a time point at which a system frame number (SFN) corresponds to 0.

Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: 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 hybrid automatic repeat request (HARQ) feedback to the second device on the PSFCH resource. Here, the PSFCH resource can be determined on the basis of a sub channel associated with the PSSCH, a slot associated with the PSSCH, a cast type of communication between the first device and the second device, an ID of the first device, and a source ID of the second device.

Abstract: According to one embodiment, proposed is a method by which a first device performs wireless communication. The method may comprise the steps of: receiving sidelink control information (SCI) related to initial transmission of a transport block from a second device through a first physical sidelink control channel (PSCCH); receiving the transport block from the second device through a first physical sidelink shared channel (PSSCH) related to the first PSCCH; determining a resource related to a physical sidelink feedback channel (PSFCH) on the basis of an index of a slot and an index of a subchannel related to the first PSSCH; transmitting an sidelink hybrid automatic repeat request negative acknowledgment (SL HARQ NACK) related to the transport block to the second device on the basis of the resource related to the PSFCH; receiving SCI related to retransmission of the transport block from the second device through a second PSCCH; and determining a time density related to a phase-tracking reference signal (PT-RS) on the basis of the fact that the SCI related to the retransmission includes a modulation coding scheme (MCS) index field indicating a reserved state. For example, the time density related to the PT-RS may be determined on the basis of a reference MCS index value related to the MCS index field indicating the reserved state.
