Title:
SIDELINK HARQ FEEDBACK OF NR V2X
Document Type and Number:
WIPO Patent Application WO/2020/145721
Kind Code:
A1
Abstract:
One embodiment of the present disclosure provides a method for a first device to transmit SL HARQ feedback information. The method comprises the steps of: receiving a PSSCH from a second device; determining a resource related to a PSFCH on the basis of a resource related to the PSSCH; determining an SL HARQ feedback option on the basis of link quality between the first device and the second device; and transmitting SL HARQ feedback information on the PSSCH to the second device through the resource related to the PSFCH, on the basis of whether or not decoding for a transmission block received through the PSSCH is successful and the SL HARQ feedback option, wherein the SL HARQ feedback option is determined as any one from among a first SL HARQ feedback option and a second SL HARQ feedback option.
