Method and device for maintaining the performance quality of a communication system in the presence of narrow band interference
First Claim
1. A system, comprising:
- a memory storing executable instructions;
a circuit coupled to the memory, wherein responsive to executing the executable instructions, the circuit performs operations comprising;
receiving information from a device that detects a narrow band interferer according to an average wideband power level, an adaptive threshold, or both, wherein the narrow band interferer is detected by the device in a wide frequency band, wherein the average wideband power level and the adaptive threshold are determined by sampling less than all narrow band signal power levels in the wide frequency band, and wherein the information is descriptive of the narrow band interferer;
determining from the received information that a source for the narrow band interferer comprises a communication device transmitting wireless signals;
determining a mitigation strategy according to the received information; and
causing a base station of a plurality of base stations of the system to reduce interference caused by the narrow band interferer according to the mitigation strategy wherein the mitigation strategy comprises causing the communication device to adjust operations of a wireless transmitter of the communication device by switching to a new operation frequency for the communication device.

18. A method, comprising:
-
receiving, by a base station, a mitigation strategy for reducing interference caused by at least one narrow band interferer detected in a wide frequency band according to an average wideband power level, an adaptive threshold, or both, wherein the average wideband power level and the adaptive threshold are determined by sampling less than all narrow band signal power levels in the wide frequency band, and wherein information obtained by the base station enables the base station to determine that a source for the narrow band interferer comprises a communication device transmitting wireless signals; creating, by the base station, a mitigation message according to the mitigation strategy to transmit to the communication device transmitting the wireless signals; and transmitting, by the base station, the mitigation message to the communication device to cause the communication device to switch to a new operation frequency for the communication device or cease the transmitting of the wireless signals by the communication device. - View Dependent Claims (19, 20)
