    摘要： A communication device within a GNSS group propagates GNSS assistance data to one or more other communication devices in the GNSS group utilizing direct device-to-device connections. The GNSS assistance data comprises ephemeris received from one or more GNSS satellites and/or predicted ephemeris. As a source device, the communication device generates, and/or acquires from other resources such as a remote location server, the predicted ephemeris. As a destination device, the communication device receives existing GNSS assistance data from a source device and/or other communication devices in the GNSS group. A GNSS position for the communication device and corresponding time information are used to refresh the received GNSS assistance data. In instances where the communication device further acts as a relay device, the refreshed GNSS assistance data is relayed to other communication devices over wired and/or wireless direct device-to-device connections utilizing appropriate communication technologies such as WiFi, Bluetooth and/or Bluetooth low energy.

    摘要： A mobile device receives data transmissions, via a coupled receiver antenna array, from a transmitter antenna array of a serving base station. The mobile device determines relative distances, with respect to the serving base station, associated with signal strength measurements on the received data transmissions. The signal strength measurements are compensated, at the mobile device and/or a remote location server, in three-dimensional space based on corresponding transmitter and/or receiver antenna pattern, and/or mobile orientation information for estimating the relative distances. The estimated relative distances are refined by fitting a function of the azimuth and elevation angles. A location for the serving base station and/or the mobile device is determined or refined based on the refined relative distances to be shared among a plurality of users of the remote location server. Fixed or adaptive antenna patterns are supported at the serving base station and/or the mobile device.

    摘要： A GNSS enabled device that is communicatively coupled to a network, receives time stamps via the network. The time stamps are generated based on reference clock signals within the network. GNSS receiver clock signal frequency may be adjusted based on the time stamps. When GNSS satellite signals and/or SRN signals are not available, the time stamps enable synchronization with GNSS satellites. Network clock signals and/or time stamps may be generated by an access point, a DSL modem, a cable modem and/or a primary reference clock within the network. A series of time stamps may be utilized for adjusting frequencies. Clock signals may be generated for adjusting frequencies based on a comparison between time stamps and oscillator or mixer output. Clock signals are generated for baseband, intermediate and/or RF frequency signal processing. GNSS satellite signals may be demodulated, correlated with a pseudonoise code sequence and/or synchronized based on the time stamps.

    摘要： Embodiments described herein include methods for improving the SINR, and therefore communication quality or rate, in the downlink of a cellular communication system. In an embodiment, the system is an orthogonal-frequency-division multiple-access (OFDMA) system. In an embodiment, a set of terminals is designated a coordinated-transmission group. The set of terminal is chosen such that the slot-allocations of the set are given special treatment to alleviate interference from other sectors or cells. In an embodiment, “zones” defined in the WiMax standard are “repurposed” to handle the coordinated-transmission, although the zone was originally intended for another purpose.
