A network traffic management device (“NTMD”) receives incoming messages over a first TCP/IP connection from a first network for transmission to a second network. Before transmitting the incoming messages onto the second network, however, the NTMD classifies the incoming messages according to some criteria, such as by assigning one or more priorities to the messages. The NTMD transmits the classified messages in the order of their message classification. Where the classification is priority based, first priority messages are transmitted over second priority messages, and so forth, for example. |

If the communication service request is Voice over Long Term Evolution (VoLTE), the method will schedule the wireless communication device to use intra-band contiguous carrier aggregation. If the communication service request is not VoLTE, and the intermodulation distortion is below a distortion threshold, the method will schedule the wireless communication device to use intra-band non-contiguous carrier aggregation. Finally, if the communication service request is not VoLTE, and the intermodulation distortion is above the distortion threshold, the method will scheduler the wireless communication device to use inter-band non-contiguous carrier aggregation. |

Blind decoding of uplink control channels
In 3GPP LTE, the uplink ACK and CQI bits are jointly coded prior to transmission to maintain a low peak to average ratio (PAR) waveform. Further, when data needs to be transmitted, the uplink control channels are multiplexed with data prior to transmission. However, due to errors on downlink (DL) and uplink (UL) assignments, an evolved Base Node (eNB) receiver needs to employ a set of rules to decode the control channels, to minimize the number of blind decoding hypotheses. This innovation describes the rules employed by a receiver to reduce complexity and computational overhead in part by assuming that the UE is responding to grant on the downlink while providing for combinations in which one or more types of grants are not received. Energy detection in accordance with metrics and normalizing for differing power controls enables selecting the correct combination for decoding. |

Direct coupled biasing circuit for high frequency applications
This invention eliminates the need for “capacitor coupling” or “transformer coupling,” and the associated undesirable parasitic capacitance and inductance associated with these coupling techniques when designing high frequency (˜60 GHz) circuits. At this frequency, the distance between two adjacent stages needs to be minimized. A resonant circuit in series with the power or ground leads is used to isolate a biasing signal from a high frequency signal. The introduction of this resonant circuit allows a first stage to be “directly coupled” to a next stage using a metallic trace. The “direct coupling” technique passes both the high frequency signal and the biasing voltage to the next stage. The “direct coupling” approach overcomes the large die area usage when compared to either the “AC coupling” or “transformer coupling” approach since neither capacitors nor transformers are required to transfer the high frequency signals between stages. |
