METHOD AND APPARATUS FOR PERFORMING CELL RESELECTION IN NEXT-GENERATION MOBILE COMMUNICATION SYSTEM OPERATING IN UNLICENSED FREQUENCY BAND

摘要

The present disclosure relates to a communication method for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and to a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology. Disclosed are a method and an apparatus for obtaining channel congestion information of an unlicensed band and performing cell reselection for a terminal, in a next-generation mobile communication system.
