Abstract
A wireless control apparatus controls beamforming performed by a wireless base station apparatus that provides a communication service to a service area which includes a plurality of spots to be irradiated with a beam including a terminal search beam and a communication beam that are not used simultaneously for irradiation, and is irradiated with a plurality of the beams and is not simultaneously covered by the plurality of beams, and the apparatus includes: an arrival direction estimation unit that estimates an arrival direction of a wireless signal transmitted by a terminal communicating with a wireless base station; and a control unit that determines whether there is an active terminal in the spots on the basis of the arrival direction estimated by the arrival direction estimation unit, and, when it is determined that there is no active terminal, controls beamforming performed by the wireless base station apparatus to decrease a frequency of the terminal search beam with which one or more of the spots determined to include no active terminal is irradiated and increases a frequency of a communication beam with which another of the spots in the service area is irradiated.
