Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING HARQ RESPONSE IN COMMUNICATION SYSTEM SUPPORTING SIDELINK COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/029547
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for transmitting and receiving an HARQ response in a communication system supporting sidelink communication. An operating method for a transmitting terminal comprises the steps of: receiving, from a base station, a higher layer signaling message including PSFCH configuration information; transmitting, to one or more receiving terminals, an SCI including data resource allocation information; transmitting, to the one or more receiving terminals, the data on a PSSCH indicated by the SCI; and performing a monitoring operation on a dedicated PSFCH resource region indicated by the PSFCH configuration information in order to receive a reception response to the SCI from the one or more receiving terminals. Therefore, the performance of the communication system can be improved.
