Abstract
A method, system, and medium are provided for mitigating radio-frequency (RF) interference at a remote radio head (RRH) of a base station due to non-linearity in at least one of the RRH components. RF-interference indicators received from one or more user devices are monitored. When the RF-interference indicators indicate that RF interference at the RRH is above a predefined threshold, then a power amplifier associated with the RRH is adjusted to operate in a saturation mode thereby reducing the generation of inter-modulation products and reducing RF interference at the RRH. When the RF-interference indicators indicate that RF interference at the RRH is below the predefined threshold, then the power amplifier is adjusted to operate in an active mode thereby optimizing signal gain.
