First Claim
1. A method for balancing loads in a wireless data communication between an airborne platform and at least two surface base stations, the method comprising:
- generating a first directional beam which is spatially directed to a first surface base station, wherein the first directional beam is generated from an antenna array on an airborne platform;
generating a second directional beam, using the same antenna array on the airborne platform, wherein second directional beam is spatially directed towards a second surface base station;
receiving at least one return signals from the first surface base station;
receiving at least one return signals from the second surface base station; and
varying amounts of data transmitted between the first surface base station and the second surface base station such that loads depend upon data requirements.

Abstract
A system and method for balancing loads in wireless data communication between an airborne platform and at least two surface base stations is provided. In this system, an antenna array located on the airborne platform is capable of transmitting more than one beamform to each of the base stations independently. Likewise, each base station may likewise be capable of beamforming data transmissions to the airborne platform. The system may vary amounts of data sent between the airborne platform and the various base stations in order to balance loads upon each base station. Determination on balancing of loads is often dependent upon the data requirements of the airborne platform. Additionally, the bandwidth usage (or availability) of the base stations may be taken into consideration when determining load balancing. This kind of load balancing enables more efficient cell to cell handovers. Further, load balancing between multiple base stations enables the airborne platform to receive busts of higher data throughput by simultaneously receiving data transmissions from the various base stations.
