    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: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to channel estimation and equalization in a cellular environment on the basis of an FBMC transmission and reception technique. A communication method of a base station according to one embodiment of the present invention may comprise the steps of: determining a reference signal (RS) pattern building block of a plurality of cells according to filter information of the plurality of cells; determining an RS pattern of the plurality of cells by using the determined RS pattern building block and the size of a resource block (RB); and transmitting, to a terminal, information about the determined RS pattern. According to one embodiment of the present invention, it is possible to provide a method and an apparatus for mapping a reference signal in a multi-cell environment.

    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.
