  • Patent number: 9769735
    Abstract: User equipment (UE) obtains system information using a foreground or background process. The system information may include cell information that distinguishes femtocells from macrocells. Given this cell information, the UE may avoid tuning to or attempting to connect to cell types that the UE does not support. For instance, the UE may avoid connection attempts to femtocells, when the UE does not support femtocell connections.

  • 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: 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: 9070048
    Abstract: A computer implemented method and apparatus for automatically identifying a representative image for an image group. The method comprises dividing an image group into one or more clusters based on an average time gap of the image group, wherein the images in the image group are in sequential timestamp order wherein the average time gap is calculated using a time span calculated from the timestamp of a first image in the image group to the timestamp of a last image in the image group; recursively dividing a largest cluster in the one or more clusters to determine a resultant cluster, wherein the resultant cluster comprises no time gaps larger than the average time gap of the resultant cluster; and identifying a representative image from the resultant cluster as an image representative for the image group.

  • Patent number: 8938239
    Abstract: A wireless communication device is disclosed that is capable of performing efficient handoffs in order to maximize connection time with either a serving or target base station. The wireless communication device performs measurements of only intra-frequency base stations to avoid retuning its radio module. Based on this information, as well as stored information relating to nearby base stations, the serving base station is able to estimate a position of the wireless communication device and compare the estimated position to positions of the known base stations in order to make a handoff decision. In addition, by storing information during measurement or handoff preparation, the device is capable of skipping handoff steps, immediately return to the serving base station after handoff failure, and/or perform streamlined PLMN searching.

  • 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.

  • Patent number: 8811918
    Abstract: Various embodiments of the present invention recognize at least two zones of operation for a communication device. In a first zone, which is sufficiently spaced away from a human head or body that SAR limits will be met, transmit power delivered to an antenna of a communication device may be maximized within any other constraints under which the communication device operates. In a second zone, which is not sufficiently spaced away from a human head or body, transmit power is redistributed such that SAR limitations are met without affecting the transmit power control loop of the communication device. For example, a second antenna physically disposed at a different location within the communication device may be used either instead of, or in addition to, the first transmit antenna in order that the SAR limits are met.

  • Publication number: 20140219112
    Abstract: Techniques are described herein for prioritizing higher priority data packets by reserving sequence numbers for assignment to higher priority data packets received after lower priority data packets are assigned sequence numbers. Higher priority data packets may also be prioritized by estimating an amount of data that can be sent in a single uplink allocation, limiting the amount of data packet data sent during a designated uplink allocation to the estimated amount of data, and encrypting high priority data packet(s) received previous to the designated uplink allocation. Higher priority data packets may also be prioritized by encrypting and placing high priority data packet(s) received in a queue, and subsequently re-encrypting any unsent lower priority data packets that were encrypted in the queue before the high priority data packet(s) were received.

  • Patent number: 8675761
    Abstract: Methods and apparatus of allocating antennas for cyclic delay diversity (CDD) transmission are disclosed. One method includes estimating a transmission channel of a transceiver having a plurality of antennas. A subset of a plurality of transceiver antennas is selected based on the estimated transmission channel. A single transceiver antenna of the subset is identified based on a channel quality of a transmission path of the single transceiver antenna. Cyclic delay diversity (CDD) signals are transmitted from the subset of the plurality of antennas, wherein a minimally delayed CDD signal is transmitted from the identified single transceiver antenna of the subset of the plurality of transceiver antennas.
