REPEATER CONTROL DEVICE, WIRELESS COMMUNICATION SYSTEM, CONTROL CIRCUIT, STORAGE MEDIUM, AND CONTROL VALUE DETERMINATION METHOD

In a repeater control device (6) for controlling a communication repeater (2) that has a beamforming function and relays a wireless communication signal including communication data addressed from a transmission device (3) to a reception device (4), the repeater control device (6) includes: a parameter determination unit that determines a gain adjustment value for adjusting input power to an amplifier that amplifies the wireless communication signal relayed by the communication repeater (2), on the basis of an evaluation value indicating communication quality in the reception device (4) and calculated on the basis of: state information indicating a state of the communication repeater (2); a beam pattern requested when the communication repeater (2) transmits the wireless communication signal to the reception device (4); transmission path information indicating a state of a transmission path between the communication repeater (2) and the reception device (4); and reception device information indicating a state of the reception device (4).
