Title:
METHOD FOR TRANSMITTING SIDELINK HARQ FEEDBACK IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/153709
Kind Code:
A1
Abstract:
An embodiment relates to a method for transmitting sidelink hybrid automatic repeat request (HARQ) feedback by a terminal in a wireless communication system, the method comprising the steps of: receiving a physical sidelink feedback channel (PSFCH) from another terminal; and transmitting, on the basis of a Uu link HARQ codebook and a sidelink HARQ codebook, Uu link HARQ feedback and sidelink HARQ feedback associated with the PSFCH to a base station, wherein the codebook type of the sidelink HARQ codebook is configured to be the same as the codebook type of the Uu link HARQ codebook, on the basis of the multiplexing of the Uu link HARQ feedback and the sidelink HARQ feedback.
