Abstract: An embodiment relates to a method for an operation of a sidelink relay UE in a wireless communication system, the method comprising: a step in which the relay UE receives a first signal from a source UE; a step in which the relay UE transmits a second signal based on the first signal to a destination UE; and a step in which the relay UE performs retransmission of the second signal to the destination UE, wherein, on the basis that the relay UE is configured to transmit a reception acknowledgement response to the first signal, the number of times that the relay UE can retransmit the second signal is obtained by excluding the number of times that the relay UE has transmitted a reception acknowledgement response to the source UE from a first maximum retransmission number.

Abstract: Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: determining a search space related to downlink control information (DCI) on the basis of a pre-configured carrier indication field (CIF) value; monitoring at least one physical downlink control channel (PDCCH) candidate within the search space; receiving the DCI on the basis of the monitoring; and performing sidelink (SL) communication with a second device on the basis of a SL resource scheduled by the DCI.

Abstract: Proposed is a method by which a first device performs wireless communication. The method may comprise the steps of: receiving, from a base station, a first dynamic grant through a physical downlink control channel (PDCCH); transmitting, to a second device, a transport block on the basis of a sidelink resource allocated by the first dynamic grant; receiving, from the second device, sidelink hybrid automatic repeat request negative acknowledgment (SL HARQ NACK) information related to the transport block; and transmitting, to the base station, the SL HARQ NACK information through a physical uplink control channel (PUCCH). For example, on the basis of transmitting the SL HARQ NACK information to the base station, a timer related to the first dynamic grant may be initiated. For example, on the basis of the timer expiring, a buffer related to the transport block may be flushed.
