Title:
BASE STATION AND CONTROL METHOD THEREFOR IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/032654
Kind Code:
A1
Abstract:
The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data transfer rate beyond a 4G system with an IoT technology, and a system thereof. The present disclosure can 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.) on the basis of a 5G communication technology and an IoT-related technology. According to an embodiment of the present invention, a method for controlling a base station supporting a multi-antenna system may comprise the steps of: generating a plurality of test signals for a plurality of antennas in a modem; controlling the plurality of generated test signals to be fed back to the modem through a plurality of feedback paths which are formed for the plurality of antennas, respectively, and do not affect each other; and identifying the plurality of test signals fed back to the modem, on the basis of the plurality of generated test signals.
