Abstract:
1. A wireless base station comprising: a multiplexer that multiplexes (a) configuration information that is used by the wireless base station to control communication with a terminal in a coverage area of the wireless base station and is to be transmitted to a first adjacent wireless base station and (b) user data to be transmitted to the terminal; an antenna for communicating with the terminal, wherein the antenna is an arrayed antenna having an array of elements; a transmitting unit that transmits, via the antenna, the configuration information multiplexed by the multiplexer to the first adjacent wireless base station and the user data multiplexed by the multiplexer to the terminal; a receiving unit that receives, via the antenna, configuration information from a second adjacent wireless base station and user data from the terminal; a demultiplexer that separates the configuration information from the second adjacent wireless base station and the user data from the terminal; a configuration information control unit that sets configuration information of the wireless base station, based on the configuration information from the second adjacent wireless base station separated by the demultiplexer; a phase control unit that incorporates the configuration information transmitted via the arrayed antenna into a directional beam whose direction is changed by controlling phases of the array of elements; a configuration information memory unit that stores the configuration information of the wireless base station and of the second adjacent wireless base station, wherein the configuration information is stored as information that indicates at least any one among coverage-area transmission power, transmission timing, position information, incoming direction of a directional beam, and coverage-area reception power, respectively, of the wireless base station and of the second adjacent wireless base station; an incoming direction estimating unit that estimates an incoming direction of a directional beam received from the second adjacent wireless base station; and an adjacent station configuration information detecting unit that determines a direction of and a position of the second adjacent wireless base station, based on position information of the wireless base station stored in the configuration information memory unit and the incoming direction of the directional beam estimated by the incoming direction estimating unit and stores to the configuration information memory unit as the configuration information, the determined direction and position, wherein the transmitting unit transmits a directional beam including the configuration information toward the second adjacent wireless base station, based on the direction and the position of the second adjacent wireless base station determined by the adjacent station configuration information detecting unit.
