1. A method for minimizing interference in a heterogeneous wireless network, the method comprising:

  • receiving, at a first access node, a reference signal from a neighboring access node within a defined portion of a transmission frame, wherein the neighboring access node is one of a plurality of neighboring access nodes, each of which is configured to schedule a corresponding plurality of reference signals using resources within the defined portion of the transmission frame;

    based on the reference signal, adding the neighboring access node to a potential interferer group associated with the first access node;

    determining a potential interference based on additional signal information received from the neighboring access node; and

    processing a first signal at the first access node based on the potential interference.
