With the increasing demands on frequency resources, spectrum sharing between the satellite and terrestrial systems becomes prominent, especially when it comes to the millimeter wave (mmWave) bands. In this paper, we propose a general spectrum sharing framework in satellite and terrestrial networks, through analyzing the interference caused by terrestrial cellular systems and nongeostationary (NGEO) systems to geostationary (GEO) systems, respectively, both in the downlink and uplink. Specially, in the spectrum sharing between terrestrial and GEO systems, two scenarios are analyzed. In the first scenario, we consider each base station (BS) equipped with one omnidirectional antenna, and in the second scenario the beamforming scheme is employed at the BSs. In light of the parameters recommended by the standards and recent results presented in the literatures on the mmWave channel model, we calculate the protection area where no cognitive users (terrestrial system or NGEO system) could transmit. The definition of protection area is to guarantee an outage performance for the GEO system. Outside the protection area, the cognitive transmitters may transmit concurrently with GEO systems. Simulations are conducted to verify the effectiveness of the proposed schemes.
