Abstract
One embodiment of the present invention discloses a method for allowing user equipment (UE), which can receive channel state information reference signals from a plurality of antenna ports, to transmit channel state information to at least one base station that controls the plurality of antenna ports. The method comprises the following steps: receiving power information of each of the plurality of antenna ports from the at least one base station; calculating channel state information on the at least one base station on the basis of the received power information and channel state information reference signals received from the plurality of antenna ports; and transmitting the calculated channel state information to the at least one base station.
