Abstract
When a scheduling executing section allocates a use downlink radio resource including in a frequency direction a frequency band, in which a known signal is not received by an uplink radio resource for known signal, from a downlink radio resource associated with the uplink radio resource for known signal to a communication terminal, a communication section generates a known signal to be received from the communication terminal in a frequency band of the use downlink radio resource in a pseudo manner when performing downlink communication with the communication terminal using the use downlink radio resource. The communication section controls transmission directivity in a plurality of antennas based on a new reception signal obtained by adding the pseudo known signal as a desired wave component to a reception signal that is received in the frequency band of the use downlink radio resource in the uplink radio resource for known signal.
