  • Patent number: 9184958
    Abstract: Systems and methods are provided for encoding and transmitting codewords. A message is encoded in two encoders. For at least one of the two encoders, the message is algebraically modified prior to being encoded. In a specific example, the message is algebraically modified prior to being encoded in each of two traditionally non-systematic encoders, with the result that the output is equivalent to that of a turbo encoder.

  • Patent number: 9161225
    Abstract: Methods, systems, and computer programs for managing mobile device applications are described. In some aspects, a mobile device application is prevented from accessing resources of a wireless network. For example, a wireless network operator system can determine that one or more mobile device applications are disapproved for use in the wireless network. In some implementations, the wireless network operator denies the disapproved mobile device applications access to the wireless network resources. In some implementations, mobile devices disable access to the wireless network by the disapproved mobile device applications.

  • Patent number: 9054780
    Abstract: A radiation power level control scheme for a wireless user equipment (UE) device. In one embodiment, a method comprises determining that a current transmission event involving the wireless UE device is commenced outside a time duration from a last transmission event. If so, responsive to the determining, the method involves disregarding or resetting a power data history associated with the wireless UE device in computing a Specific Absorption Rate (SAR) value for the wireless UE device during the current transmission event. Otherwise, at least a portion of the power data history may be used in computing the SAR values.

  • Patent number: 9049746
    Abstract: Devices and methods are disclosed for concurrently managing multimode communications devices. In various embodiments, a wireless communication device comprises a first radio configured to use a first Radio Access Technology (RAT) and a second radio configured to use a second RAT. Processing logic in the wireless device is configured to monitor and manage the state machines of said first and second radios. The processing logic is further configured to place the first radio in an active operational mode and to place the second radio in a reduced functionality operational mode. Control messages for the second radio are then received and processed via the first radio while the second radio is in the reduced functionality operative mode.

  • Publication number: 20150092676
    Abstract: A system and method may use mm-wave superspots to download high volumes of data to a moving or stationary mobile device traveling along a travel route that the moving mobile device is traveling. A macrocell in communication with the mobile device may predict the route that the mobile device is traveling, such as via GPS location, moving speed and direction, map information, etc. Alternatively, the route being taken may be determined by wireless communication, such as between the mobile device and a macrocell and/or superspot. The macrocell and/or superspot may determine whether (1) there are any mm-wave superspots along the predicted or known route that the mobile device is taking; (2) there is any data that is requested or remaining to download to the moving mobile device; and/or (3) the received signal quality, channel conditions, and/or macrocell traffic to the mobile device are favorable for superspot downloading.

  • Publication number: 20140369245
    Abstract: A data transfer system may coordinate the transfer of user data and control data using a self-contained data channel without using a separate control channel in a time period between set-up and tear-down of the self-contained data channel. For example, a plurality of data transfer resources may be established in a self-contained data channel between user equipment and a network controller. User data is transferred between the user equipment and the network controller in at least one of the plurality of data transfer resources of the self-contained data channel. Additionally, control data is transferred between the user equipment and the network controller in at least one of the plurality of data transfer resources of the self-contained data channel.

  • Patent number: 8803999
    Abstract: Tilt imparted to video images captured by a handheld electronic communication device is identified and corrected by the disclosed method and apparatus for image orientation. The handheld device includes image capturing capability and an orientation sensor, which provides a signal representative of orientation relative to gravity to calculate an angle of rotation for the captured images suitable to compensate a difference between the orientation of the handheld device and the orientation relative to gravity. The handheld device also includes a receiver wherein the angle of rotation is recovered and used to determine the changes needed substantially eliminate the difference between the orientation of the captured images and the orientation relative to gravity.

  • Publication number: 20140211762
    Abstract: Systems, apparatuses, and methods for a handover procedure in heterogeneous networks are provided. In particular, an intermediate handover (IHO) is introduced. Certain aspects of the disclosure involve, a method, performed at a serving base station of a wireless communications network, where the serving base station serves a user equipment (UE). The method includes receiving a downlink (DL) signal quality indicator from the UE; and determining, from the signal quality indicator, whether a condition for an intermediate handover (IHO) state is satisfied. If the condition for the intermediate handover state is satisfied, the serving base station can initiate the intermediate handover state.
