Title:
METHOD AND DEVICE FOR DISABLING HARQ FEEDBACK IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/071329
Kind Code:
A1
Abstract:
Provided are a method for a first device to perform wireless communication, and a device for supporting same. The method includes the steps of: generating a medium access control protocol data unit (MAC PDU) in which a hybrid automatic repeat request (HARQ) feedback is enabled; transmitting sidelink control information (SCI) including information related to the enabling of the HARQ feedback for the MAC PDU to a second device; performing an (N-1)-th transmission of the MAC PDU on the second device; transmitting SCI including information related to the disabling of the HARQ feedback for the MAC PDU to the second device; and performing an N-th transmission of the MAC PDU on the second device, wherein N may be the maximum number of transmissions related to MAC PDU.
