Method and apparatus for beam selection in mobile communication system

Abstract

The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and safety related service, or the like) on the basis of a 5G communication technology and an IoT related technology. Disclosed are a method and an apparatus for reselecting a beam and selecting a suitable beam to be camped on, by a terminal, in order to be provided with a service in a next generation mobile communication system operating on the basis of a beam. Disclosed according to an embodiment of the present invention are a method and an apparatus for performing the same, the method comprising the steps of: receiving system information including first beam selection priority information; receiving a radio resource control (RRC) message including second beam reselection priority information; identifying whether the terminal has camped on a suitable beam; and applying one of the first beam reselection priority information and second beam reselection priority information on the basis of the result of the identification.
