Abstract
In the fifth-generation (5G) networks, millimeter- wave (mmWave) bands have drawn great attention for the large amount of possible bandwidth. Meanwhile, satellite communications have also shown great interest in the mmWave bands, especially the Ka band. Under such a circumstance, the spectrum sharing between the satellite and terrestrial communication systems becomes prominent. In this paper, we analyze the interference caused by terrestrial cellular systems to the geostationary (GEO) system in two transmission modes. In order to protect the GEO system, we construct a protection radius where the terrestrial transmitters must locate outside. Simulations are conducted to verify the effectiveness of the proposed scheme.
