METHOD AND DEVICE FOR SELECTING ANTENNA OR BEAM IN WIRELESS COMMUNICATION SYSTEM USING BEAM-FORMING TECHNIQUE

摘要

The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate beyond 4G system, and a system for same. The present invention can be applied to smart services (e.g. smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security- and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed are a device and a method enabling explicit or implicit indication of beam selection in order to select a beam between a terminal and a base station in a wireless communication system using a beam-forming technique, and enabling selection of a beam in correspondence with same.
