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. A method for transmitting uplink control information in a wireless communication system is provided. The method includes receiving configuration information on a plurality of bandwidth parts (BWPs) from a base station; receiving downlink control information and downlink data from the base station; receiving BWP adaptation information which indicates a change of an active BWP from the base station; identifying an uplink control channel resource for transmitting acknowledgement information in response to the downlink data; and transmitting the acknowledgement information on the identified uplink control channel resource to the base station.
