The present disclosure relates a communication technique that fuses a 5G communication system supporting a higher data transmission rate following a 4G system with IoT technology and a system therefor. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail, security and safety related services, etc.) on the basis of 5G communication technology and IoT related technology. A method for transmitting a scheduling request (SR) of a terminal according to the present invention comprises the steps of: receiving SR configuration information; performing channel sensing of an unlicensed band in case that the SR is triggered in the unlicensed band; and waiting for SR transmission in case that a channel is occupied as a result of the channel sensing.
