ACTIVE ANTENNA CONTROL DEVICE, CONTROL METHOD THEREOF, AND NONTRANSIENT COMPUTER-READABLE MEDIUM ON WHICH PROGRAM HAS BEEN STORED

WIPO Patent Application WO/2020/158103

A1

According to an embodiment of the invention, an active antenna control device (1) is provided with: a plurality of transceivers (11_1 to 11_M) configured to be able to transmit a plurality of radio signals that are caused to have directivity via a plurality of antenna elements (A_1 to A_M); a current position acquisition unit (12) that acquires the current position of a first mobile terminal selected, as a future position estimation target, from among a plurality of mobile terminals; a past position acquisition unit (13) that acquires a past position of the first mobile terminal; a future position estimation unit (14) that estimates a future position of the first mobile terminal from the current position and past position of the first mobile terminal; and a control unit (15) that, in a case where if one of the plurality of radio signals is emitted toward the future position of the first mobile terminal, the degrees of degradation in communication quality of the mobile terminals other than the first mobile terminal will be within an allowable range, then causes the radio signal to be emitted toward the future position of the first mobile terminal.
