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.

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 channel state information (CSI) acquisition method of a base station in a mobile communication system 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. Also, a terminal for reporting CSI to the base station and an operation method of the terminal be provided. 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.
