METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIDELINK HARQ FEEDBACK INFORMATION

Abstract:

Provided are methods and apparatuses for transmitting HARQ feedback information for sidelink transmission. In particular, a method of a transmitting user equipment (UE) is provided for transmitting the HARQ feedback information for the sidelink transmission. The method may include: receiving, from the base station, resource assignment information on a physical uplink control channel (PUCCH) for transmitting, to the base station, the HARQ feedback information for the sidelink transmission to a receiving UE; generating the HARQ feedback information based on a physical sidelink feedback channel (PSFCH) for the sidelink transmission received from the receiving UE; and transmitting the HARQ feedback information over the PUCCH based on the resource assignment information to the base station.
