Satellite communication system, gateway, satellite repeater, communication network control station, satellite communication method, and terminal

In a satellite communication system to relay communication between a terminal and a gateway installed on the ground through a satellite repeater, the satellite repeater forms a user link beam for communicating with the terminal and a feeder link beam for communicating with the gateway in a same area, and changes frequency or polarization association with respect to each of the user link beam and the feeder link beam, based on a traffic situation. Thus, a capacity that can be communicated by the beam may be changed after satellite launching..
