Flexible Bandwidth Assignment To Spot Beams
First Claim
1. A method of operating a satellite system, comprising:
- providing by a satellite a first spot beam;
providing by the satellite a second spot beam, the second spot beam is adjacent to and at least partially overlaps the first spot beam;
generating the first spot beam to include a first combination of frequency and polarization and a reserved combination of frequency and polarization during a first time period;
generating the second spot beam to include a second combination of frequency and polarization during the first time period;
generating the first spot beam to include the first combination during a second time period; and
generating the second spot beam to include the second combination and the reserved combination during the second time period.

Abstract
A wireless communication platform utilizes flexible bandwidth assignment to re-allocate bandwidth between spot beams. The platform may assign a first combination of frequency and polarization (FP) to a first spot beam and a second combination of frequency and polarization to a second spot beam that is adjacent and at least partially overlapping the first spot beam. The platform may assign to the first spot beam a reserved combination of frequency and polarization during a first time period, and at second time, assign the reserved combination to the second spot beam. The platform may also assign the reserved combination simultaneously to adjacent spot beams by managing user of the reserved combination by geographically isolated terminals in the spot beams. The platform may further assign different portions of the reserved combination to adjacent spot beams without geographical limitations.
