The present invention relates to a method and an apparatus for transmitting and receiving a HARQ response in a communication system supporting side chain communication. An operation method of a transmitting terminal includes: receiving a high-layer signaling message including PSFCH configuration information from a base station; transmitting an SCI including resource allocation information of the data and configuration information of HARQ feedback for the data to the plurality of receiving terminals; transmitting data to the plurality of receiving terminals in the PSSCH indicated by the SCI; and performing a monitoring operation to receive a sequence mapped to the HARQ response for the data from the plurality of receiving terminals in the PSFCH resource region indicated by the PSFCH configuration information. Therefore, the performance of the communication system can be improved.
Description
technical field [0001] The present disclosure relates to sidechain communication technology, and more particularly, to a technology for transmitting and receiving a hybrid automatic repeat request (HARQ) response for sidelink communication performed in a multicast scheme. Background technique [0002] In order to deal with the rapidly increasing wireless data after the commercialization of the fourth generation (4G) communication system (eg, Long Term Evolution (LTE) communication system, LTE-Advanced (LTE-A) communication system), Consider the fifth-generation (5G ) communication system (for example, New Radio (NewRadio, NR) communication system). The 5G communication system can support Enhanced Mobile Broadband (eMBB) communication, Ultra-Reliable and Low-Latency communication (Ultra-Reliable and Low-Latency communication, URLLC), massive Machine Type Communication (massive Machine Type Communication, mMTC), etc. [0003] The 4G communication system and the 5G communicat...
