Abstract
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) are provided. 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. According to embodiments of the present disclosure, The system includes a base station having a large number of transmission antennas of a two dimensional (2D) antenna array structure can prevent excessive feedback resource allocation for transmitting channel state information reference signals (CSI-RSs) and increase of channel estimation complexity of a terminal, and the terminal can effectively measure channels of a large number of transmission antennas and can report to the base station feedback information configured through the measurement.
