Shown is a method in which a communication terminal feeds back, to a strong-interference base station, information regarding a reference signal received from the strong-interference base station. This communication system includes a plurality of base stations (100) ((100a, 100b)) and a plurality of communication terminals (200) ((200a, 200b)), wherein the communication terminal (200a) calculates a desired channel matrix on the basis of a reference signal received from a desired base station (100a) which is currently communicating with the communication terminal (200a), calculates an interference channel matrix on the basis of a reference signal received from a strong-interference base station (100b) in which the power of a radio wave interfering with the communication terminal (200a) is strongest, and notifies the desired base station (100a) of the desired channel matrix and the interference channel matrix by an uplink message. |
