METHODS AND SYSTEMS FOR MODIFYING SATELLITE ANTENNA CELL PATTERNS IN RESPONSE TO TERRESTRIAL REUSE OF SATELLITE FREQUENCIES

摘要

Space-based wireless radiotelephone communications (100) are provided in asatellite footprint over a satellite radiotelephone frequency band (fD, fU).The satellite footprint is divided into satellite cells in which satelliteradiotelephone frequencies of the satellite radiotelephone frequency band arespatially reused. At least one of the satellite radiotelephone frequencies(f'D, f'U) that is assigned to a given satellite cell in the satellitefootprint is terrestrially reused outside the given satellite cell. Aradiation pattern of at least the given satellite cell is modified to reduceinterference with the at least one of the satellite radiotelephone frequenciesthat is terrestrially reused outside the given satellite cell.
