CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS FOR 2-DIMENSIONAL MASSIVE MIMO COMMUNICATION SYSTEM

摘要

The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -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. A channel state information feedback method and apparatus of a terminal is provided for measuring channel quality and reporting the measurement result to a base station in the mobile communication system supporting multi-carrier multiple access scheme such as Orthogonal Frequency Division Multiple Access (OFDMA). A feedback method of a terminal in a mobile communication system includes acquiring reference antenna port information for at least one Reference Signal (RS), receiving the at least one Reference Signal (RS) from a base station, estimating at least one channel carrying the at least one Reference Signal (RS), and transmitting feedback information on at least one estimated channel to the base station.
