Abstract
As UAV Internet of things applications continue to grow, so does interest in the development of air-to-ground (ATG) systems, which can effectively expand communication system coverage. To maximize utilization of frequency resources, the ATG system adopts frequency reuse with the 5G system on the ground. This research studies the co-channel interference between ATG and 5G at 3.5 GHz as well as the neighboring channel interference with C-band fixed satellite service. We do research on various ATG aircraft flying altitudes and horizontal distances, which yields multiple potential interference reduction strategies. Finally, numerical results are shown to demonstrate the efficacy and productivity of our proposed methods.
