    Abstract: 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. A method and apparatus for transmitting/receiving Channel State Information (CSI) is provided for use in a Full Dimensional Multiple Input Multiple Output (FD-MIMO) system. A channel state information (CSI) reception for a base station according to the present disclosure for use in a wireless communication system includes transmitting CSI process configuration information to a terminal, transmitting a CSI Reference Signal (CSI-RS) to the terminal based on the CSI process configuration information, and receiving the CSI generated based on CSI-RS measurement result from the terminal, wherein the CSI process configuration information is configured to measure channel states of horizontal and vertical antenna arrays, the CSI includes a joint Channel Quality Indicator (CQI), and the joint CQI is determined based on the CQIs for the horizontal and vertical antennas arrays.

    Abstract: For converging a 5th-Generation (5G) communication system and supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), a channel state information (CSI) acquisition method includes transmitting CSI configuration information to a terminal, selecting a beam for transmitting a beamformed CSI reference signal (BF-CSI-RS) to the terminal, transmitting the BF-CSI-RS to the terminal using the selected beam, and notifying the terminal of a beamforming update. A base station for acquiring CSI in a mobile communication system includes a transceiver configured to transmit and receive signals, and a controller configured to control the transceiver to transmit CSI configuration information to a terminal, to select a beam for transmitting a BF-CSI-RS to the terminal, to transmit the BF-CSI-RS to the terminal using the selected beam, and to notify the terminal of a beamforming update.
