Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system with a technology for Internet of Things (IoT). Methods and apparatuses are provided in which first sidelink data and second sidelink data are received from one or more terminals. It is determined whether a first resource for transmitting first feedback information for the first sidelink data and a second resource for transmitting second feedback information for the second sidelink data overlap each other. When the first resource and the second resource overlap each other, feedback information corresponding to one of the first feedback information and the second feedback information having a higher priority, is transmitted to the one or more terminals. A priority of each of the first feedback information and the second feedback information is based on sidelink control information scheduling each of the first sidelink data and the second sidelink data.
