| Abstract(in English) | The flight control of drones and the transfer of captured video data by using the mobile communication network will be expected. We are proposing a "three-dimensional spatial cell configuration" in which ground cells and sky cells share the same frequency at each base station by utilizing 5G beamforming technology. In order to evaluate the proposed method accurately, a radio wave propagation model that can be used in the sky cell is necessary. Since drones flying over the sky are generally outlook, propagation is based on Nakagami-Rice model, and it is necessary to model the K-factor. In this paper, we propose a highly accurate "3D spatial circular orbit measurement method" for the K factor in the sky when the direction of radio waves arrival is unknown, and clarify its measurement accuracy. |
