  • Patent number: 9907006
    Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.

  • Patent number: 9730271
    Abstract: Systems and methods for providing dynamic substream definition and handover are provided. In embodiments, a user device includes a multiple radio access technology (RAT) communications modules and a communication controller. Each RAT communication module is further configured to communicate using a different RAT. The user device identifies available networks for communication. Then, the controller determines whether a need to split a communications stream exists (e.g., the user device is engaged in a bandwidth intensive application). If the communications stream is to be split, the controller defines the substreams (either equally or unequally) and assigns a first substream to a communication pathway in a first available network and assigns a second substream to a communication pathway in a second available network. The destination then recombines the substreams. In embodiments, the controller inserts synchronization in the substreams.

  • Patent number: 9537684
    Abstract: Embodiments of a method and apparatus for performing an adaptive transmission scheme in a frequency division duplexing communication system based on channel state information estimated using an open-loop mode are described herein. In one example, the method includes estimating an impulse response of a channel using a signal received over a first frequency band of the channel from a device, transforming the impulse response into a frequency response of the channel, and subsequently performing the adaptive transmission scheme using the frequency response to transmit a signal to the device over a second frequency band of the channel that is different from the first frequency band.

  • Patent number: 9521268
    Abstract: A wireless communication device communicating with a serving base station in a wireless communication environment may have one or more applications running. When seeking to handover from the serving base station to a target base station, the wireless communication device adjusts the configurations of the applications based on the new communication link properties. Likewise, when an application is loaded that prefers communication link properties that exceeds a current communication link's capabilities, the wireless communication device may seek out and hand over to other communication links. By cooperatively coordinating the functionality of installed applications with communication link properties, the wireless communication device can maintain high levels of device and application functionality.

  • Patent number: 9356757
    Abstract: A wireless communication device is disclosed that includes multiple antennas capable of being used for carrier aggregation, and that uses its additional antennas to scan for available base stations without interfering with connectivity to a current base station and/or while maximizing useable bandwidth. The wireless communication device may scan using multiple of the antennas to maximize scanning results and reduce scan time, and may scan for available base stations using some of its antennas while maintaining its connection to the current base station with its other antennas. The device can also analyze control channel portions of received signals to utilize periods of signal inactivity to scan for available base stations, such as DRX or SPS modes of operation. In addition, the device can measure various parameters to optimize its scanning capabilities.

  • Patent number: 9173178
    Abstract: A method and system are provided in which a mobile device may be operable for long term evolution (LTE) communication or some other wireless technology via two or more transmit antennas. The device may comprise a power amplifier for each transmit antenna with substantially similar maximum power being provided by both amplifiers. A power headroom value may be determined in the device based on path loss values between the transmit antennas and a base station and the maximum transmit power for each transmit antenna. Transmission via one of the transmit antennas may occur concurrently with transmission via another of the transmit antennas. The device may generate an indication of the determined power headroom value for communication to the base station. The power headroom value may be reported periodically or in response to a change in the power received at the base station.

  • Patent number: 8942184
    Abstract: A method and apparatus for link adaptation in a wireless communication network is provided. The method includes computing a first channel quality parameter based on one or more channel quality parameters. The one or more channel quality parameters are associated with a communication link between a Mobile Station (MS) and a Base Station (BS). The method further includes determining a qualifying transmission unit to compute a correction parameter. The correction parameter is computed based on the first channel quality parameter and one or more transmission parameters. The one or more transmission parameter is associated with the communication link. Thereafter, the method schedules a transmission mode of the communication link based on a second channel quality parameter. The second channel quality parameter is estimated based the first channel quality parameter and the correction parameter.

  • Patent number: 8825102
    Abstract: Systems and methods for regulating transmit power in a mobile station to comply with SAR limits are disclosed. A mobile station may include a processor, transmitter, and proximity sensor. The transmitter is configured to operate at a transmit power controlled by a first transmit power limit. The proximity sensor identifies how close the mobile station is to a human head. A transmit power regulator, implemented on the processor, determines the cumulative energy radiated by the transmitter over a specified number of frames. If the cumulative energy exceeds an energy limit based on a SAR limit, and the proximity sensor indicates that the mobile station is close to a human head, the transmit power regulator may decrease the transmit power limit of the transmitter.
