1. A method for interference mitigation in a heterogeneous network including one or more femto cells within a macro cell coverage area, the method comprising:

  • transmitting, at a femto station, wireless communication signals using a plurality of femto station resources to communicate with at least one femto user equipment (UE) within a femto coverage area of the femto station;

    detecting, at the femto station, a macro UE operating within the femto coverage area;

    in response to detecting the macro UE, shutting off a first portion of the femto station resources and transmitting the wireless communication signals using a second portion of the femto station resources, wherein the first portion of the femto station resources are a source of interference to the macro UE.
