Patent ID: 11963157

Abstract:
The present disclosure relates to a communication technique for convergence of an IoT technology and a. 5G communication system for supporting a higher data transfer rate beyond a 4G system, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety-related services, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present invention provides a method and apparatus for transmitting and receiving power headroom information in a beam-forming system. In addition, the present invention provides a method of a first module of a base station in a wireless communication system, the method comprising the steps of: when an unlicensed band is required to be used, transmitting a. resource allocation request message with respect to the unlicensed band to a second module; receiving a response message in response to the request; and allocating a resource of the unlicensed band to a terminal on the basis of the response.
