    Abstract: Systems and methods for Multi-Radio Access Technology (RAT) Carrier Aggregation (MRCA) wireless wide area network (WWAN) assisted wireless local area network (WLAN) discovery, association, and flow switching are disclosed. One system comprises a control signaling module in a wireless device that includes a WWAN radio integrated with a WLAN radio. The control signaling module is configured to communicate WWAN control signaling and WLAN control signaling via a WWAN radio connection of the wireless device. A dynamic flow mapping module 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: A system and method for handoff are provided. A mobile station performs a make-before-break handoff of a control channel between a serving and target base station and a break-before-make handoff of a traffic channel between the serving and target base stations. The traffic channel handoff is performed after the control channel handoff has completed.

    Abstract: Briefly, in accordance with one or more embodiments, two or more cells are configured to perform coordinated multipoint (CoMP) transmission for one or more user equipment devices with a common media access control (MAC) or a common radio resource control (RRC). Measurement information is received from the one or more user equipment devices. One or more of the cells may be deactivated, or one or more additional cells may be activated for coordinated multipoint transmission based at least in part on the measurement information.

    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.

    Abstract translation: 各种发明实施例涉及用于无线宽带网络中的持久和/或动态分配的信息元素（IE）的布置，并且包括优化技术以消除来自下行链路（DL）-Persistent-IE，上行链路（UL）的重复信息字段， 一致的IE，DL-IE和UL-IE。 消除重复信息字段会降低MAP开销。 此外，实施例涉及使用相同的混合自动重传请求（HARQ）区域来包含持久和非持久性分配的方法。 对于持久性和非持久性分配，使用相同的HARQ区域进一步降低了MAP开销，因为它需要单个报头来定义HARQ区域，而不是定义两个不同HARQ区域所需的两个报头：一个用于持续 分配，第二个用于非持续分配。
