Claim:
1. A method for mitigating interference at an access node, the method comprising: determining, based on an interference metric for a first wireless device exceeding an interference criteria, that communication between the first wireless device and a cell of an access node is experiencing interference from a neighboring cell; identifying at least one neighboring cell in which one or more beam formed signals are transmitted as a potential interference source; instructing the identified neighboring cell to terminate transmission of a beamformed signal to at least a second wireless device that receives a beamformed signal from the neighboring cell; determining whether the interference metric for the first wireless device continues to exceed the interference criteria after termination of the beamformed signal; and identifying the second wireless device as an interference source when the interference metric for the first wireless device does not continue to exceed the interference criteria.
