METHOD AND APPARATUS FOR TRANSMITTING SIDELINK HARQ FEEDBACK INFORMATION

Abstract:

Provided are methods and apparatuses for transmitting sidelink hybrid automatic repeat request (HARQ) feedback information. The method of a receiver user equipment (UE) includes: receiving configuration information on a physical sidelink feedback channel (PSFCH) resource set, receiving a physical sidelink shared channel (PSSCH) from a transmitter UE, determining a PSFCH resource used for transmitting the HARQ feedback information in response to the PSSCH in the PSFCH resource set based on pre-configured identification information, and transmitting the HARQ feedback information using the PSFCH resource.
