Abstract: 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 utilizing an unlicensed frequency band as a supplementary band is used in a Long Term Evolution (LTE) system. A secondary component carrier management method of a base station according to the present disclosure includes configuring a secondary component carrier of a second band to a terminal connected to the base station in a first band, determining whether a packet is present over a bearer allowing transmission on the secondary component carrier, and deactivating/releasing the secondary component carrier when no packet is present over the carrier.
