    Abstract: Systems and methods for Multi-Radio Access Technology (RAT) Carrier Aggregation (MRCA) wireless wide area network (WWAN) assisted wireless local area network (WLAN) flow mapping and flow routing are disclosed. One system comprises a dynamic flow mapping module that is configured to form a flow-mapping table to dynamically map service flows between the WWAN radio and the WLAN radio in the wireless device. A flow routing module is configured to route data packets to one of the WWAN radio and the WLAN radio in the wireless device based on the flow-mapping table to transmit and receive the data packets via the wireless device.

    Abstract: Systems and methods for opportunistic cross radio access technology (RAT) bandwidth allocation are disclosed. The system comprises wireless wide area network (WWAN) radio configured to be used as a primary cell (PCell) to communicate with a dual mode mobile wireless device on a licensed band and a wireless local area network (WLAN) radio integrated with the WWAN radio and configured to be used as a secondary cell (SCell) to provide additional wireless connectivity to the dual mode mobile wireless device in an unlicensed band that is controlled by the PCell. The PCell provides network access and mobility control for the dual mode mobile wireless device and also supports an opportunistic cross carrier bandwidth allocation through a cross RAT coordination module in the downlink and uplink of the SCell in the unlicensed band.

    Abstract: The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.
