Abstract: A communication system capable of realizing a three-dimensional network of the fifth generation mobile communication with low propagation delay in a radio communication is provided. The communication system comprises a radio relay station that relays a radio communication with the terminal apparatus. The radio relay station is provided in a floating object that is controlled so as to be located in a floating airspace with an altitude of 100 [km] or less by an autonomous control or an external control. When the floating object is located in the floating airspace, the radio relay station forms a three-dimensional cell in a predetermined cell-formation target airspace between the floating object and a ground level or a sea level.

Abstract: A communication terminal apparatus, a terrestrial cellular base station and a mobile communication system are provided, which are capable of being shared in a terrestrial cellular mobile communication system and a satellite mobile communication system, and preventing an interference between beams in a satellite mobile communication system while preventing an interference between both systems by a simple switching control of radio resources. Time slots of radio resources are allocated so as not to overlap with each other between the terrestrial cellular mobile communication system and the satellite mobile communication system and so as not to overlap with each other between adjacent beams corresponding to each of two or more beams of the satellite mobile communication system. When locating in a beam area covered by any one of two or more beams of the satellite mobile communication system, a radio communication of the satellite mobile communication system is performed using the time slots allocated to the beam covering the beam area.
