Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING HARQ RESPONSES IN WIRELESS COMMUNICATION SYSTEM SUPPORTING SIDELINK COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/029557
Kind Code:
A1
Abstract:
Disclosed are a method and an apparatus for transmitting and receiving HARQ responses in a communication system supporting sidelink communication. The method of operating a transmitting terminal comprises the steps of: receiving, from a base station, a higher layer signaling message including PSFCH configuration information; transmitting, to a plurality of receiving terminals, SCI including resource allocation information of data and configuration information for HARQ feedback for the data; transmitting the data to the plurality of receiving terminals in a PSSCH indicated by the SCI; and performing a monitoring operation to receive, from the plurality of receiving terminals, sequences mapped to HARQ responses for the data in a PSFCH resource region indicated by the PSFCH configuration information. Therefore, the performance of a communication system can be improved.
