Abstract

In this letter, we propose an advanced incumbent protection method that considers three-dimensional aspects of 5G New Radio (NR) beamforming for dynamic spectrum access (DSA). The proposed method further introduces a concept of area-based protection to satisfy protection criteria for a primary system (PS) with inaccurate location information. We show some computer simulation results for deploying a 5G based secondary system (SS) in a millimeter-wave band which is primarily assigned to a fixed wireless access (FWA) based PS. The results demonstrate that the proposed method increases allowable transmission powers of the SS by up to 15 dB, compared to a conventional method.
