Abstract: Systems and methods provide cross-layer bearer splitting and cross-RAT retransmission in a RAN-based WLAN/WWAN integrated network. A link aggregation transmitter is configured to receive, from a WLAN stack lower layer protocol, a WLAN transmission confirmation signal and a WLAN congestion status, and to receive, from a WWAN stack lower layer protocol, a WWAN transmission confirmation signal and a WWAN congestion status. The link aggregation transmitter dynamically splits the bearer traffic across the WWAN link and the WLAN link based at least in part on the WLAN transmission confirmation signal, the WLAN congestion status, and the WWAN congestion status.

Abstract: Uplink (UL) data splits between LTE and WLAN can be go supported in cellular networks. The split can be UE controlled or network controlled. Both UE and network controlled bearer split architectures can be supported. The reporting of Uplink Buffer Status (BSR) and the subsequent data allocation can depend on what option is supported by the network. For UE controlled UL data splits, the UE determines a traffic split ratio between LTE and WLAN. The split can be based on local link conditions. For network controlled UL data splits, the network (e.g. a Link Aggregation Scheduler at the eNB) is responsible for making bearer split decisions. The decisions can be based on link qualities, available traffic and quality of service (QoS) requirements of associated users. The split can be based on a per bearer threshold, an eNB configured ratio, or an implicit inference based on a UL grant.

Abstract: Techniques for 60 GHz long term evolution (LTE)—wireless local area network (WLAN) aggregation (LWA) for keeping a 60 GHz channel alive for fifth generation (5G) and beyond are discussed herein. An apparatus of a 5G/long term evolution (LTE) evolved NodeB (eNB) is connected to a 60 GHz access point (AP) via an Xw interface, and has a baseband circuit with one or more baseband processors. The baseband circuit encodes one or more measurement events, wherein upon receipt by a user equipment (UE) sets a trigger to measure a 60 GHz access point.

Abstract: Systems and methods for bearer splitting among multiple radio links are disclosed herein. User equipment (UE) may be communicatively coupled to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB) by multiple radio links (e.g., an LTE link and a WLAN link). A transmitter may dynamically determine a splitting policy for how to split traffic among each link (e.g., what proportion to send over each link). In some embodiments, the transmitter may determine the splitting policy explicitly based on lower layer metrics. Alternatively, or in addition, each radio access interface may request data when a transmission opportunity becomes available, and the splitting policy may be determined implicitly from the data requests. For a UE, the splitting policy may be determined with network assistance, which may include a resource allocation for an LTE link, a probability of successful transmission over a WLAN link, and/or the like.

Abstract: A method in a mobile communication terminal includes intercepting a message in which the terminal indicates to a base station a fill level of a buffer holding data that is pending for transmission to the base station. A future processing power, which will be required by processing circuitry in the terminal for transmitting the data to the base station, is predicted based on the intercepted message. An operating point of the processing circuitry is set corresponding to the predicted future processing power, by configuring at least one parameter selected from among a supply voltage and a clock frequency of the processing circuitry. The processing circuitry is operated at the set operating point to process the data pending in the buffer.

Abstract: The invention relates to communication systems and to systems and methods for implementing adaptive call admission control (CAC) in such systems. Adaptive call admission control can determine what CPE to base station calls (connections) are allowed at any given time. CAC, coupled with precedence, can further determine what connections are suspended if less bandwidth is available than is currently committed. Multiple techniques are disclosed to select connections for suspension. These techniques include suspending enough connections through the affected CPE until there is enough bandwidth to meet the remaining commitment, randomly (or in a round robin fashion) choosing connection to suspend from the entire set of connection, and using precedence priority levels.

Abstract: On embodiment of the system and method provides asymmetric adaptive modulation which allows uplink and downlink subframes of data to be transmitted between a base station and a CPE with different modulation schemes, thus increasing the efficiency of downlink transmissions while maintaining the stability of uplink transmissions. In systems with multiple CPEs, each CPE and base station pair can independently select their uplink and downlink modulation techniques. The system and method are also adaptive in that they adjust the modulation schemes based on, for example, signal to noise ratio measurements or bit error rate measurements.
