摘要： Disclosed are: a communication technique for fusing, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4 G system and subsequent systems; and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service and the like) based on 5G communication technology and IoT related technology. The present disclosure presents a method by which a base station determines the approximate location of a terminal on the basis of a reception power report, and sets a codebook subset on the basis of the approximate location of the terminal so as to reduce a channel state report burden.
