PROBLEM TO BE SOLVED: To sufficiently improve communication quality even when a wireless terminal receives an interference signal in downlink direction communication.SOLUTION: A wireless communication system 10A comprises a control device 100A which controls a wireless base station BS1 for transmitting a first wireless signal for which a channel A is used to a wireless terminal UE1 via a plurality of first transmission antennas and a wireless base station BS2 for transmitting a second wireless signal for which the channel A is used to a wireless terminal UE5 via a plurality of second transmission antennas. The wireless terminal UE1 transmits interference information which is based on an arriving direction D1 of the second wireless signal to the wireless terminal UE1. On the basis of the interference information, the control device 100A transmits, to the wireless base station BS2, control information for turning a null point of a directional beam formed by the second transmission antennas to the arriving direction D1. |
