Abstract
Systems and methods are also described for mitigating interference at an access node. It may determined, 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. At least one neighboring cell in which one or more beamformed signals are transmitted is identified as a potential interference source. The identified neighboring cell may be instructed to terminate transmission of a beamformed signal to at least a second wireless device. It may then be determined whether the interference metric for the first wireless device continues to exceed the interference criteria after the termination of the beamformed signal. And the second wireless device may be identified as an interference source when the interference metric for the first wireless device does not continue to exceed the interference criteria.
