An interference control method that takes into consideration beamforming for dynamic spectrum access

Abstract

As 5G comes into full-fledged use after 2020, the shortage of spectrum resources is expected to continue. In order to use the IMT frequency bands, which was specified at WRC-19, it is necessary to implement advanced dynamic spectrum access between primary systems to which frequency bands are already allocated and 5G systems. In this paper, we consider an interference control method that takes into consideration the beamforming characteristics of secondary systems in radio stations.
