MODIFYING SATELLITE ANTENNA CELL PATTERNS IN RESPONSE TO TERRESTRIAL REUSE OF SATELLITE FREQUENCIES.

摘要

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