Patent ID: 8830985

Claim:
A method of detecting and mitigating interference between a wireless frequency division duplex (FDD) communications device in communication with an FDD base station and a wireless time division duplex (TDD) communications device, wherein an FDD uplink frequency band includes first and second frequencies, such that the first frequency is adjacent to a TDD transmission frequency band, the method comprising: determining, using a processor, whether a monitored value of an operational parameter of the FDD device is within a fixed range of a maximum value of the operational parameter; and responsive to a determination that the monitored value of the operational parameter of the FDD device is within the fixed range of the maximum value of the operational parameter, configuring the FDD base station such that the FDD base station receives data packets from the FDD device on a reduced-interference frequency selected from within the FDD uplink frequency band such that the reduced-interference frequency is either closer to the second frequency than the first frequency, or the reduced-interference frequency is at a center of the FDD uplink frequency band.
