METHOD AND APPARATUS FOR MITIGATING SATELLITE DOWNLINK INTERFERENCE OF SATELLITE AND TERRESTRIAL INTEGRATED SYSTEM
First Claim
1. 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, the method comprising:
- dividing an area of a first satellite beam into at least one sector;
determining a first sector at which a satellite terminal is located among the at least one sector;
determining a second sector corresponding to the first sector among at least one sector that is included in a first terrestrial cell; and
allocating at least one of first frequency resources for the second sector to the satellite terminal,wherein the first terrestrial cell is located within an area of a second satellite beam adjacent to the first satellite beam.

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.

10. A satellite that is included in a satellite communication system that shares a frequency resource with a terrestrial communication system, the satellite comprising:
-
a memory; and a processor that is connected to the memory and that performs operation for allocating a frequency resource to a satellite terminal, wherein the processor determines a first sector at which a satellite terminal is located among N (N is a natural number) sectors that are included in a first satellite beam of the satellite, determines a second sector corresponding to the first sector among N sectors that are included in a first terrestrial cell of the terrestrial communication system, and allocates at least one of frequency resources for the second sector to the satellite terminal, and wherein the first terrestrial cell is located within an area of a second satellite beam of the satellite adjacent to the first satellite beam. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method in which a base station (BS) of a terrestrial communication system that shares a frequency with a satellite communication system allocates a frequency resource, the method comprising:
-
determining a frequency resource that is allocated to a second satellite beam adjacent to a first satellite beam at which the BS is located; and allocating at least one of first frequency resources, except for frequency resources that are allocated to the first satellite beam and the second satellite beam among M (M is the natural number of 2 or more) frequency resources, to at least one terrestrial terminal of the terrestrial communication system. - View Dependent Claims (17, 18, 19, 20)
