The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method by which a terminal, during uplink signal transmission: receives, from a base station, first information for indicating transmission of uplink control information and/or data in a specific subframe; receives, from the base station, second information for indicating transmission of the uplink control information and/or the data in the specific subframe; and determines the uplink control information and/or the data to be transmitted in the specific subframe on the basis of a capability of the terminal and transmits the determined uplink control information and/or data in the specific subframe.
