METHOD AND APPARATUS FOR SELECTING ANTENNA OR BEAM IN A WIRELESS COMMUNICATION SYSTEM USING BEAM-FORMING

摘要

The present disclosure relates to a communication technique for combining IoT technology with a 5G communication system for supporting a higher data transmission rate after a 4G system and a system thereof. The present disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or a connected car, a health care, a digital education, a retail business, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology. A method for selecting a beam of a terminal in a wireless communication system using a beamforming scheme includes the steps of: generating setting information of a beam resetting reference signal process and a beam resetting reference signal identifier for a specific terminal to be transmitted to the terminal through upper layer signaling; generating downlink control information and transmitting the downlink control information to the terminal; transmitting the beam resetting reference signal based on the downlink control information and the upper layer signaling; and receiving beam resetting information reported from the terminal. Accordingly, the present invention can increase the efficiency of data transmission and reception in a base station.
