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:
- assigning a first terrestrial frequency to first transmissions in a first base station subsector associated with a first terrestrial BWA base station that is in a first geographical area, wherein the first terrestrial frequency is used as a first satellite uplink frequency;
- nulling the first transmissions at the first terrestrial frequency in the first base station subsector associated with the first terrestrial BWA base station to mitigate interference to communication using the first satellite uplink frequency on a satellite uplink of the MSS from the first terrestrial BWA base station;
- 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;
- 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;
- monitoring a plurality of satellite frequencies at the MSS satellite for interference caused by one or more of the first and second terrestrial BWA base stations at the MSS satellite;
- and
- identifying a satellite frequency of the plurality of satellite frequencies responsive to the interference caused by the one or more of the first and second terrestrial BWA base stations being below a threshold interference for use for MSS communication.
