Coordinated satellite-terrestrial frequency reuse
First Claim
1. A method of operating a terrestrially-based wireless communications system having a terrestrial coverage area overlaid on a first satellite coverage area of a satellite-based wireless communications system having a plurality of satellite coverage areas, the method comprising:
- reusing frequencies assigned to satellite coverage areas adjoining the first satellite coverage area in the terrestrial coverage area based on relative geographical separation between the terrestrial coverage area and the respective adjoining satellite coverage areas.

Abstract
A system and method of operation for efficiently reusing and/or sharing at least a portion of the frequency spectrum between a first satellite spot beam and a second satellite spot beam, and/or an underlay terrestrial network associated with a second satellite spot beam. The spectrum is efficiently reused and/or shared between respective spot beams and/or associated underlay terrestrial systems in a manner minimizes interference between the respective satellite and terrestrial systems.
