Abstract
Beamforming for radio communication (uplink) from a relay apparatus to a donor base station is performed accurately. A relay apparatusis a relay apparatusfor relaying communication between a terminal deviceand a donor base stationand includes: an amplitude and phase measurement unitthat measures an amplitude and phase of radio communication from the donor base stationto the relay apparatus; and a beam adjusterthat performs beamforming with respect to the donor base stationby adjusting amplitudes and phases from a plurality of antennas used at the relay apparatusby measuring the amplitude and the phase by using the amplitude and phase measurement unit, wherein during a time slot when the terminal devicedoes not exist in a service area of the relay apparatus, the relay apparatusdetects no existence of the terminal devicein the service area and stops access radio, the amplitude and phase measurement unitmeasures the amplitude and the phase, and the beam adjusterperforms the beamforming with respect to the donor base station, after which the access radio is restarted.
