Document Type and Number:
WIPO Patent Application WO/2018/073983
Kind Code:
A1
Abstract:
Provided is a relay device capable of appropriately performing beamforming in wireless communication from a relay device to a donor base station while suppressing beam interference nearby to the greatest extent possible. Thus, a relay device 20 equipped with an amplitude/phase measurement unit 25 for measuring the amplitude and phase of the wireless communication from the donor base station 30 to the relay device 20, a beam adjustment unit 27 for performing beamforming by adjusting the combination of the multiple antennas, and a base station determination unit 29 for determining the base station, wherein a beamforming adjustment is implemented in a manner such that a relatively strong beam is directed at the donor base station 30, and a relatively weak beam is directed at the base stations other than the donor base station 30.
