Title:
METHOD AND DEVICE FOR REPORTING HARQ FEEDBACK TO BASE STATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/071243
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication and a device for supporting same are provided. The method can comprise the steps of: receiving, from a base station, information related to a sidelink (SL) resource and information related to a physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control packet data unit (MAC PDU) in which hybrid automatic repeat request (HARQ) feedback has been disabled, on the basis of the SL resource; generating ACK related to the transmission of the MAC PDU in which the HARQ feedback has been disabled; and transmitting the ACK to the base station on the basis of the PUCCH resource.
