1. One or more non-transitory computer-readable media having computer executable instructions embodied thereon that, when executed, perform a method of mitigating radio-frequency (RF) interference at a remote radio head (RRH) of a base station due to non-linearity in one or more of the RRH components including at least a power amplifier, wherein the power amplifier is configured to operate in an at least an active mode and a saturation mode, the method comprising:

  • receiving RF-interference indicators from a plurality of user devices communicating with the base station;

    using the RF-interference indicators;

    adjusting the power amplifier such that the power amplifier operates in the active mode when the RF-interference indicators indicate that RF interference at the RRH is below a predefined threshold; and

    adjusting the power amplifier such that the power amplifier operates in the saturation mode when the RF-interference indicators indicate that RF interference at the RRH is above the predefined threshold.
