METHOD AND APPARATUS FOR GENERATING AND TRANSMITTING CHANNEL FEEDBACK IN MOBILE COMMUNICATION SYSTEM EMPLOYING TWO DIMENSIONAL ANTENNA ARRAY

摘要

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Provided are a method and user equipment for sending feedback information to a base station. The method includes receiving a Channel Status Indication Reference Signal (CSI-RS) from the base station; generating feedback information on a basis of the received CSI-RS; and transmitting the generated feedback information to the base station, wherein generating feedback information includes selecting a precoding matrix for each antenna port group of the base station and selecting an additional precoding matrix on a basis of a relationship between the antenna port groups of the base station.
