    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: A user equipment (UE) capable of communicating with a base station (BS) includes a transceiver configured to receive a signal comprising a CSI process configuration, wherein the CSI process configuration comprises a CSI-RS resource configuration to identify a CSI-RS resource and a CSI-RS on the CSI-RS resource, and transmit a precoding matrix indicator to the base station, and a controller configured to derive the precoding matrix indicator utilizing the CSI-RS on the CSI-RS resource. When the CSI-RS resource configuration indicates 4 CSI-RS ports: the precoding matrix indicator has a 3-bit size when a rank to derive the precoding matrix indicator is one; the precoding matrix indicator has a 3-bit size when the rank is two; the precoding matrix indicator has a 2-bit size when the rank is three; and the precoding matrix indicator has a 1-bit size when the rank is four.
