    Abstract: A method in which a satellite or a terrestrial earth station that is included in a satellite communication system that shares a frequency resource with a terrestrial communication system allocates a frequency resource is provided. The satellite divides an area of a first satellite beam into at least one sector. The satellite determines a first sector in which a satellite terminal is located among the at least one sector. The satellite determines a second sector corresponding to the first sector among at least one sector that is included in a first terrestrial cell. The satellite allocates at least one of first frequency resources for the second sector to the satellite terminal. The first terrestrial cell is located within an area of a second satellite beam adjacent to the first satellite beam.
