METHOD FOR CONTROLLING SIDELINK HARQ FEEDBACK AND DEVICE THEREFOR

WIPO Patent Application WO/2020/209658

A1

The present disclosure relates to a method and a device for providing a V2X service in a next generation radio access technology (new RAT). The present embodiments relate to a method for a terminal to control a sidelink HARQ feedback operation, the method comprising the steps of: receiving, from a transmitting terminal, group cast sidelink data through a physical sidelink shared channel (PSSCH); determining, on the basis of positional information of the transmitting terminal, whether to transmit HARQ feedback information of the group cast sidelink data; and, when it is determined to transmit the HARQ feedback information, transmitting the HARQ feedback information.
