| 摘要 |
The present invention relates to a base station apparatus (1) in a point-to-multipoint wireless communication system. The base station apparatus (1) is provided with: a directional antenna (11), a terminal-station-apparatus direction calculation unit (16), an antenna-direction calculation unit (17), and an antenna-direction adjustment unit (18). The directional antenna (11) has directivity. The terminal-station-apparatus direction calculation unit (16) calculates, on the basis of the positions of a plurality of terminal station apparatuses and the position of the base station apparatus (1), the directions of the plurality of terminal station apparatuses with reference to the position of the base station apparatus (1). The antenna-direction calculation unit (17) calculates a direction in which the directional antenna (11) is to be directed, on the basis of the directions of the plurality of terminal station apparatuses, the channel quality of the plurality of terminal station apparatuses, necessary channel qualities indicating channel qualities requested by the plurality of terminal station apparatuses, and a directional pattern (15b) of the directional antenna (11). The antenna-direction adjustment unit (18) directs the directional antenna (11) in the direction in which the directional antenna (11) is to be directed. |
