    Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to the present disclosure, a method for operating a beamformed reference signal by a base station and terminal in a communication system, and the terminal, are provided. The method includes transmitting, to a terminal, control information indicating whether a first codebook is used for generating feedback information on a downlink reference signal. The first codebook is used if generating feedback information on the beamformed reference signal and is generated based on a number of antenna ports and a number of ranks.

    Abstract: Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher than that of a 4G communication system, such as LTE. Disclosed is a communication method of a base station using a channel state information reference signal (CSI-RS) in a mobile communication system, the method comprising the steps of: receiving a sounding reference signal (SRS) from a terminal; selecting a precoding matrix by using the received SRS; transmitting a CSI-RS by using the selected precoding matrix; receiving a CSI report from the terminal, and determining a transmission parameter on the basis of the CSI report; and transmitting data to the terminal by applying the determined transmission parameter thereto, wherein the CSI-RS is aperiodically transmitted.
