SYSTEMS AND METHODS FOR CONTROLLING BASE STATION SECTORS TO REDUCE POTENTIAL INTERFERENCE WITH LOW ELEVATION SATELLITES
First Claim
1. A method of reducing interference between satellite radioterminal communications systems comprising:
- transmitting and receiving satellite uplink frequencies in a Time Division Duplex (TDD) mode by a wireless base station in a first sector thereof while simultaneously refraining from transmitting and receiving satellite uplink frequencies in the TDD mode by the wireless base station in a second sector thereof that points to a low elevation angle satellite.

Abstract
Interference between satellite radioterminal communications systems may be reduced by transmitting and receiving satellite uplink frequencies in a Time Division Duplex (TDD) mode by a wireless base station in a first sector thereof, while simultaneously refraining from transmitting and receiving satellite uplink frequencies in the TDD mode by the wireless base station in a second sector thereof that points to a low elevation angle satellite. Satellite uplink frequencies may be transmitted and received in the TDD mode by a satellite that communicates with radioterminals in the second sector.
