1. A method for operating a coordinating controller, the method comprising:
- receiving, by the coordinating controller, signal power measurements of communications devices served by communications controllers controlled by the coordinating controller;
determining, by the coordinating controller, an interference level at one or more of the communication controllers in accordance with the signal power measurements;
generating, by the coordinating controller, relationship information for the communications controllers in accordance with the interference level at the one or more of the communication controllers; and
determining, by the coordinating controller, frequency reuse modes for the communications controllers controlled by the coordinating controller in accordance with the relationship information for the communications controllers.

Abstract
A system and method for self-organized inter-cell interference coordination are provided. A method for controller operations includes receiving signal power measurements at a controller, determining an interference level based on the signal power measurements, generating relationship information based on the interference level, and determining frequency reuse modes for communications controllers controlled by the controller based on the relationship information.
