发明名称 BASE STATION DEVICE, COMMUNICATION SYSTEM, AND CONTROL METHOD OF TILT ANGLE OF ANTENNA
摘要 A base station device includes a first antenna which transmits a radio signal in a downlink, a second antenna which receives a radio signal in an uplink, and a tilt angle control unit which controls a tilt angle of the first antenna and the second antenna to decrease a difference in a position of a cell boundary of the downlink and a position of the cell boundary of the uplink based on a communication quality of the downlink and a communication quality of the uplink with respect to a first base station device and on the communication quality of a downlink and a communication quality of the uplink with respect to an adjacent second base station device.
