Method and apparatus for transmission or reception of sidelink feedback in communication system

Abstract

The disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data transfer rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to intelligent services (for example, smart home, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety-related services, etc.) on the basis of a 5G communication technology and an IoT-related technology. In addition, the disclosure relates to a method performed by a terminal for feeding back a hybrid automatic repeat request (HARQ) and to a terminal for performing the method, the method including: generating HARQ feedback information for data that is scheduled for the terminal in at least one slot; determining a transmission timing of the HARQ feedback information based on a minimum processing time for transmission of a physical sidelink feedback channel (PSFCH) of the terminal; and transmitting the HARQ feedback information based on the determined timing, wherein the minimum processing time for the PSFCH transmission is determined based on at least one of a subcarrier spacing, a configuration of a resource pool, and a time interval between a PSSCH and the PSFCH.
