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.

Claim (Index 21):
A base station using a channel state information reference signal (CSI-RS) in a mobile communication system, the base station comprising:\n a transceiver; and a controller configured to:\n receive a sounding reference signal (SRS) from a user equipment, \n select a precoding matrix based on the received SRS, \n transmit the CSI-RS based on the selected precoding matrix, \n receive channel state information (CSI) reporting from the user equipment, \n determine a transmission parameter based on the CSI reporting, and \n transmit data to the user equipment based on the determined transmission parameter, \n wherein the CSI-RS corresponds to an aperiodic CSI-RS.
