Coordinated satellite-terrestrial frequency reuse
First Claim
1. A method of assigning to and/or reusing by a wireless terrestrial communications system at least one frequency of a space-based communications system that is configured to selectively use geographically a set of frequencies, the method comprising:
- configuring at least one terrestrial cell of the terrestrial communications system having a service area that at least partially overlaps with a service area of the space-based communications system and assigning to, reusing by and/or borrowing by the at least one terrestrial cell the at least one frequency based on a predetermined geographic distance between the at least one terrestrial cell and an area served by the space-based system using the at least one frequency.

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.
