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 (814) and a second satellite spot beam (802), and/or an underlay terrestrial network (816) associated with a second satellite spot beam (802). The spectrum is efficiently reused and/or shared between respective spot beams (802, 814) and/or associated underlay terrestrial systems (816) in a manner minimizes interference between the respective satellite and terrestrial systems.
