RAN APPLICATIONS FOR INTER-CELL INTERFERENCE MITIGATION FOR MASSIVE MIMO IN A RAN

Some embodiments of the invention provide a system for mitigating inter-region interference for multiple regions serviced by multiple RAN (Radio Access Network) base stations. The system includes a first RAN application for generating a map that identifies, for each particular region serviced by each particular RAN base station, a set of one or more sub-regions receiving interfering signals from other RAN base stations. The system includes a second RAN application for (1) using the generated map and a set of input received from the plurality of RAN base stations to define, for each sub-region in the set of sub-regions, policies for allocating carrier resources of the particular RAN base station to carrier beams transmitted by the particular RAN base station to the sub-regions with the interfering signals, and (2) providing the defined policies to the RAN base stations for which the policies are defined.
