Abstract
The present invention relates to a 5G or pre-5G communication system to be provided to support a higher data transmission rate after a 4G communication system such as LTE. A base station (BS) capable of communicating with user equipment (UE) according to the present invention comprises: a transmission and reception part for transmitting a downlink signal including an eight-port channel state information-reference signal (CSI-RS) depending on the configuration of the CSI-RS with respect to the UE and a CSI-RS on a physical downlink shared channel (PDSCH), and receiving uplink signals including a precoder matrix indicator (PMI), which has been derived using the eight-port CSI-RS, from the UE; and a controller for converting the PMI into one among predetermined precoding vectors. The UE comprises: a transmission and reception part for receiving downlink signals including the configuration of the CSI-RS on the PDSCH transmitted by the BS and an eight-port CSI-RS depending on the configuration of the CSI-RS, and transmitting uplink signals including the PMI; and a controller for decoding the configuration of the CSI-RS from the downlink signals and deriving the PMI using estimated channel values based on the eight-port CSI-RS. The PMI is mapped to one among precoding vectors.
