Abstract
Methods of mitigating interference to a Mobile Satellite Service (MSS) satellite from terrestrial Broadband Wireless Access (BWA) base stations are provided. A method includes nulling first transmissions in a first base station subsector associated with a first terrestrial BWA base station that is in a first geographical area, and nulling second transmissions in a second base station subsector associated with a second terrestrial BWA base station that is in a second geographical area different from the first geographical area.

A method of mitigating interference to a Mobile Satellite Service (MSS) satellite from terrestrial Broadband Wireless Access (BWA) base stations, the method comprising:
- nulling first transmissions in a first base station subsector associated with a first terrestrial BWA base station that is in a first geographical area;
- and
- nulling second transmissions in a second base station subsector associated with a second terrestrial BWA base station that is in a second geographical area different from the first geographical area.
A method of mitigating interference to a Mobile Satellite Service (MSS) satellite from terrestrial Broadband Wireless Access (BWA) base stations, the method comprising:
- monitoring a plurality of frequency bands for interference caused by the terrestrial BWA base stations at the MSS satellite;
- and
- identifying a frequency band of the plurality of frequency bands for use for MSS communication for which the interference caused by the terrestrial BWA base stations is below a threshold interference.
A method of mitigating interference to a Mobile Satellite Service (MSS) satellite from terrestrial Broadband Wireless Access (BWA) base stations, the method comprising:
- receiving, from a MSS controller, a frequency band for which the interference caused by the terrestrial BWA base stations at the MSS satellite is below a threshold;
- and
- refraining from assigning resource blocks that use the frequency band to terrestrial BWA User Equipments (UEs) for terrestrial BWA communication between the terrestrial BWA base stations and the terrestrial BWA UEs.
A method of mitigating interference to a Mobile Satellite Service (MSS) satellite from a terrestrial Broadband Wireless Access (BWA) base station, the method comprising:
- receiving, at the terrestrial BWA base station, a pilot signal on a satellite downlink frequency;
- and
- adjusting terrestrial BWA communication on a satellite uplink frequency that corresponds to the satellite downlink frequency, responsive to the pilot signal.
A method of mitigating interference to a Mobile Satellite Service (MSS) satellite from a terrestrial Broadband Wireless Access (BWA) base station, the method comprising:
- transmitting a pilot signal from the MSS satellite to the terrestrial BWA base station on a satellite downlink frequency;
- and
- receiving reduced interference from the terrestrial BWA base station on a satellite uplink frequency that corresponds to the satellite downlink frequency, responsive to the pilot signal.
