Multiple base stations’ beamforming gain control based on spatial information for spectrum sharing

Local 5G is expected as a system to provide a communication service within a certain specific area and it is also supposed to apply the spectrum sharing which is attractive techniques to utilize the frequency resources. In order to utilize those shared spectrum, it is required to improve the interference control among systems which use the shared spectrum. In this paper, we examine and report the application of the control method with the arrangement of multiple base station when compensating for the coverage of the part where the received power locally decreases.
