Claim Text:
1. A method for interference management by a Wi-Fi device, the method comprising: monitoring, by the Wi-Fi device, signaling energy on a communication channel in a frequency band associated with the Wi-Fi device; comparing the monitored signaling energy with a known waveform signature corresponding to Long Term Evolution (LTE) operation; identifying a presence of an LTE interferer on the communication channel in the frequency band associated with the Wi-Fi device based on the comparison; correlating a periodicity of the monitored signaling energy with a plurality of predefined patterns associated with LTE uplink and downlink (UL/DL) configurations; classifying the LTE interferer as operating in accordance with an associated one of the UL/DL configurations based on the correlation; and performing interference mitigation based on the classification and the associated UL/DL configuration, wherein the interference mitigation comprises dual-rate control that maintains, based on the associated UL/DL configuration, separate power tracking loops for (i) packet transmissions during LTE UL subframes and (ii) packet transmissions during LTE DL subframes.
