Abstract
A networked computing system capable of mitigating interference amongst neighboring base stations. The networked computing system includes multiple base stations, user equipment, a network resource controller, and a data communications network facilitating data communications amongst all network devices. A serving base station is configured to acquire interference metrics from its local user equipment and then generate an aggregate representation from the acquired interference metrics. The network resource controller is configured to acquire the aggregate representation, determine an interference reduction associated with a neighbor base station for each of the user equipment serviced by the serving base station, determine a power schedule for the first base station based on the aggregate representation and the determined interference reduction, and then modify a power schedule for the neighbor base station based on the determined interference reduction.
