Abstract
A method is disclosed for use in a frequency division duplex (FDD) wireless network including a base station (BS) and a user equipment controller (UE) communicating through a medium having an uplink communication channel supporting communications from the UE to the BS, and a downlink communication channel supporting communications from the BS to the UE. The method includes identifying an uplink frequency spectrum in the uplink communication channel affected by an interfering signal, and determining the uplink power level of the interfering signal and whether the interfering signal is caused by passive intermodulation distortion (PIM). In response to determining that that the interfering signal is caused by PIM, the method includes adjusting, based on the uplink frequency spectrum and the uplink power level of the interfering signal, one or more of a downlink power level of a downlink transmission signal and a downlink frequency range in the downlink communication channel.
