Original Abstract Submitted
Proposed is a method for operation of a first device () in a wireless communication system. The method may comprise the steps of: transmitting, on the basis of an initial transmission resource, SCI for scheduling of a PSSCH to a second device () via a PSCCH; transmitting, on the basis of the initial transmission resource, an MAC PDU to the second device () via the PSSCH; receiving HARQ feedback related to the PSSCH from the second device () via a PSFCH resource; and carrying out, on the basis of the HARQ feedback being HARQ NACK information, partial sensing for resource reevaluation or preemption for at least one retransmission resource.
