METHODS AND SYSTEMS FOR CONFIGURING SATELLITE ANTENNA CELL PATTERNS IN RESPONSE TO TERRESTRIAL USE OF SATELLITE FREQUENCIES
First Claim
1. A method of providing wireless communications, the method comprising:
- providing space-based communications using a space-based component comprising an antenna having a radiation pattern, the radiation pattern comprising a spatial distribution of gain; and
configuring the spatial distribution of gain responsive to terrestrial communications to reduce a level of interference.

Abstract
Space-based wireless radiotelephone communications are provided in a satellite footprint over a satellite radiotelephone frequency band. 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 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.
