Frequency sharing between ground and sky cells by applying beamforming and MU-MIMO canceller in mobile communication.

Abstract (in Japanese) (See Japanese page) 
(in English) To enable the use of mobile communication systems in the sky, we propose a "three-dimensional space cell structure" that utilizes beamforming technology in base station antennas to spatially divide terrestrial cells and aerial cells, allowing the same frequency to be shared between ground and sky. This paper evaluates the communication quality when applying beamforming and MU-MIMO cancelers to the base station to improve the quality of the uplink, and further, when applying 2x2 orthogonal polarization MIMO (Multiple-Input Multiple-Output) transmission using orthogonal polarization antennas at the base station as a transmission method.
