Abstract: An antenna device includes an antenna array having a plurality of antennas. An RF structure has a component that can vary phase response over frequency through the antenna array. A controller controls the component to create frequency-direction multi-beams from the antenna array. The antenna device can be part of an RF receiver and the RF structure can include a transmission line for each of the plurality of antennas and an RF signal connection to the transmission line for each of the plurality of antennas. The component can include a programmable delay element and a programmable phase element. The controller can set a delay of each programmable delay element and a phase each of programmable phase element in real-time to create frequency-direction multi-beams from the antenna array.

Abstract: A method, a system, and a computer program product for enabling reliable millimeter links in wireless communications systems. One or more beams associated with a plurality of communication paths is trained to determine one or more angles corresponding to the beams at which the beams are received by at least one of a first communication device and a second communication device. Using the determined one or more angles, at least one communication path in the plurality of communication paths is selected for transmission of one or more data packets between the first and second communication devices. Using the selected communication path, one or more data packets are transmitted.

Abstract: Some embodiments of the invention provide a method for mitigating inter-region interference for multiple regions serviced by multiple RAN (Radio Access Network) base stations. The method is performed for each region serviced by each particular RAN base station. The method identifies a set of one or more sub-regions receiving interfering signals from other RAN base stations.

Abstract: 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.

Abstract: Some embodiments of the invention provide a method for operating a first base station of a radio access network (RAN). At the first base station, the method receives a set of allow and block policies for allocating carrier resources to carrier beams utilized by the first base station for mobile devices within a first region serviced by the first base station, said first region located near a second region serviced by a second base station. At the first base station, the method identifies a first mobile device operating in the first region. At the first base station, the method uses the set of allow and block policies to allocate carrier resources to a carrier beam used to communicate with the first mobile device in the first region.
