1. An apparatus of a dual-mode base station, the apparatus comprising:

  • a memory; and

    processing circuitry in communication with the memory, the processing circuitry arranged to;

    configure a primary cell (PCell) to communicate in a licensed band; and

    configure a secondary cell (SCell) to communicate over a plurality of extension carriers to support carrier aggregation with the PCell;

    configure a short range extension carrier to provide the SCell;

    provide cross carrier scheduling of the short range extension carrier;

    control activation and deactivation of the short range extension carrier;

    obtain one or more network measurements; and

    offload data from the PCell to the SCell in response to a determination made by the PCell based on the one or more network measurements.
