METHOD AND APPARATUS FOR OPERATING HARQ PROCESS IN NR V2X

WIPO Patent Application WO/2021/206532

A1

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.
