  • Patent number: 9837726
    Abstract: The multi-band active integrated MIMO antenna is a planar structure that includes active devices such as power amplifiers (PA) for transmit modes, as well as low-noise-amplifiers (LNA) for receive modes or complete transceivers (both PA and LNA for bi-directional operation, i.e. transmit and receive modes simultaneously). The antenna provides active loading to facilitate a diversity advantage expected from 4G and 5G wireless systems. The integrated active amplifier device within the antenna increases system throughput while supporting multi-band operation for multi-wireless standards. Moreover, integration with the radio frequency front end eases matching while providing higher gain.

    Abstract: A software application installed on a mobile device moving along a path periodically measures and records a parameter along with the GPS position associated with the measurement. Path data files are recorded on the device's internal memory and may be transferred to and from a repository database to share data between devices. Data may be displayed in the form of a map allowing users to navigate along paths to locations with desired parameter levels. This parameter may be cellular signal strength, allowing users in areas with no usable signal to find a usable signal. If data are preloaded onto a device, signal strength maps can be displayed even when the device has no current data connection. Parameters can be calibrated to compensate for differing sensitivities between device models. Screen dimming and audio cues can reduce battery consumption and the software can alert users when they stray from a desired path.

The computing device then determines that the first state of the first certificate store differs from a second state of a second certificate store located on a second client device. Finally, the computing device sends an update to the second client device, wherein the update comprises a change set representing a difference between the updated record and the second certificate store.

  • Patent number: 9755964
    Abstract: A communication device includes a data source that generates data for transmission over a bus, and a data encoder that receives and encodes outgoing data. An encoder system receives outgoing data from a data source and stores the outgoing data in a first queue. An encoder encodes outgoing data with a header type that is based upon a header type indication from a controller and stores the encoded data that may be a packet or a data word with at least one layered header in a second queue for transmission. The device is configured to receive at a payload extractor, a packet protocol change command from the controller and to remove the encoded data and to re-encode the data to create a re-encoded data packet and placing the re-encoded data packet in the second queue for transmission.

  • Patent number: 9756532
    Abstract: Systems and methods for Secondary Cell (sCell) selection for wireless devices operating according to a carrier aggregation scheme in a cellular communications network are disclosed. In one embodiment, a network node obtains a list of potential sCells for a wireless device. The network node blindly selects an sCell for the wireless device from the list of potential sCells. The network node then configures the wireless device with the selected sCell. Blindly selecting the sCell for the wireless device makes it possible to avoid the use of measurement gaps and reduce throughput loss, according to some embodiments.

  • Patent number: 9756537
    Abstract: A method and apparatus for transmitting a cell shaping/un-shaping indication in a wireless communication system is provided. A first eNodeB (eNB) transmits a cell shaping/un-shaping indication which indicates cell shaping/un-shaping of a cell, managed by the first eNB, in an active antenna system (AAS) to a second eNB. The cell shaping means that main coverage of the cell is maintained unchanged but an edge of the cell can be adapted to load demand. The cell un-shaping means that coverage of the cell goes back to original coverage.

    Abstract: A method includes determining at a User Equipment (UE) that logged Minimization of Drive Tests measurements (MDT) is configured and thus a plurality of MDT measurements are to be made and results of said measurements are to be stored for reporting at a later time. It is determined that said measurements are to be stopped (suspended) for various reasons (such as the UE being in any cell selection mode or camping on any cell) and information indicating a reason why said measurements are to be stopped (suspended) is stored in the measurement log.

  • Patent number: 9749800
    Abstract: Described herein are methods and apparatus for controlling wireless scans used to determine the location of a portable electronic device. In described embodiments, the portable electronic device determines if user notifications are currently suppressed (i.e., if the device is operating in a “do not disturb” mode). In the case that user notifications are currently suppressed on the portable electronic device, the interval between the wireless scans used to determine the location of the portable electronic device is increased. Furthermore, in described embodiments, the portable electronic device determines its location. Then based on its location, it determines a travel time to a boundary (e.g., a geo-fence) and adjusts the frequency of wireless scans used to determine the location of the portable electronic device based on the travel time.

  • Patent number: 9749773
    Abstract: Control plane devices are selected by an access point for establishment of end-to-end control plane for a user equipment (UE) coupled to (or requesting to couple to) the access point. In one aspect, the selection is based on data extracted during the setup and/or registration messages communicated between the access point and UE during attachment of the UE to the access point and/or an internal derived mapping of the control pane devices to the access point. In one example, a control plane device pool is segregated to and different sets of control plane devices are selected and utilized to handle traffic associated with different services to improve scaling and flexibility.

  • Patent number: 9743438
    Abstract: Provided are a radio communication method, a radio communication system, and a mobile station, by which it is possible to easily establish initial access between mobile stations in D2D communication. A mobile station 200A transmits a synchronization-use signal to be used for establishment of initial access with a mobile station 200B toward the mobile station 200B on the basis of control information received from a cell to which the mobile station 200A is connected. The mobile station 200B receives the synchronization-use signal on the basis of the control information received from the cell. Moreover, the mobile station 200B determines transmission power and a transmission timing of a response signal on the basis of the received synchronization-use signal, and transmits the response signal toward the mobile station 200A. The mobile station 200A and the mobile station 200B start D2D communication on the basis of the synchronization-use signal and the response signal.

  • Patent number: 9743448
    Abstract: A first radio station (1) requests or instructs a second radio station (2) to prepare for communication with a radio terminal (3) on a second cell (20) while a first radio connection on a first cell (10) with the radio terminal (3) is established. Further, the first radio station (1) instructs the radio terminal (3) or the second radio station (2) to establish a second radio connection on the second cell (20) with the radio terminal (3) while maintaining the radio connection on the first cell (10) with the radio terminal (3). It is thus for example possible to enable a single radio terminal to establish radio connections with cells of a plurality of radio stations, in order to achieve carrier aggregation of cells operated by different radio stations.
