Systems and methods for interference detection in shared spectrum channels

A method of detecting interference to a satellite receiver from a mobile communications device in communication with a cellular node of a mobile cell in proximity to the satellite receiver, the method executed by a processor of a server in operable communication with the cellular node, and the method comprising the steps of:

• detecting a wireless broadcast signal from the cellular node within a target frequency band, the wireless broadcast signal including at least one primary synchronization signal (PSS) receivable by the mobile communications device;
• determining, from the detected wireless broadcast signal, the presence of the at least one PSS;
• and
• instructing the cellular node, based on the determined presence of the at least one PSS within the captured wireless broadcast signal, to (i) operate at full power, (ii) operate at a second power level lower than full power, or (iii) cease operation.

A satellite receiver configured to detect interference from a mobile communications device in communication with a cellular node of a mobile cell proximate the satellite receiver, the satellite receiver comprising:

• a processor in operable communication with the satellite receiver;
• and
• a memory device (i) in operable communication with the processor, and (ii) including computer-executable instructions stored therein, which, when executed by the processor, cause the processor to:
• (i) detect a wireless broadcast signal from the cellular node within a target frequency band, the wireless broadcast signal including at least one primary synchronization signal (PSS) detectable by the mobile communications device;
• (ii) determine, from the detected wireless broadcast signal, the presence of the at least one PSS;
• and
• (iii) instruct the cellular node, based on the determined presence of the at least one PSS within the captured wireless broadcast signal, to (i) operate at full power, (ii) operate at a second power level lower than full power, or (iii) cease operation.
