Patent ID: 8681660

Claim:
A method of detecting and mitigating interference between a wireless time division duplex (TDD) communications device operational with a TDD base station and a wireless frequency division duplex (FDD) communications device, the method comprising: processing, using a processor operatively associated with an FDD base station, quality-indicator reports received from the FDD device indicating a reception quality of one or more FDD data packets at the FDD device, wherein the processing comprises: calculating a correlation value representing a correlation between an actual quality-indicator report pattern related to the quality-indicator reports and an expected quality-indicator report pattern determined based on a frame configuration of a TDD frame; and comparing the calculated correlation value with a predetermined threshold value to determine if the reception at the FDD device has experienced interference from the TDD device; and responsive to a determination that the reception at the FDD device has experienced interference from the TDD device, adjusting, using the processor, a downlink configuration of the FDD base station to mitigate interference from the TDD device.
