Abstract: Interference with another terminal caused by joint transmission of a plurality of wireless base stations is appropriately estimated. A wireless base station includes a wireless control section and a communication section. The wireless control section, when performing joint transmission with a joint wireless base station, generates a reference signal for estimating interference given to a wireless terminal connected to another wireless base station, and determines a setting regarding joint transmission in accordance with a result of estimation of interference based on the reference signal. The communication section transmits a reference signal to another wireless base station or a wireless terminal, and announces, to a joint wireless base station, a setting regarding joint transmission.
