Abstract: A global navigation satellite system (GNSS) device may receive GNSS correction data from a correction data source and obtain a first carrier-phase measurement of a first GNSS signal having a first carrier frequency, and a second carrier-phase measurement of a second GNSS signal having a second carrier frequency. The GNSS device may apply the GNSS correction data to the first carrier-phase measurement, the second carrier-phase measurement, or both. The GNSS device may, subsequent to applying the GNSS correction data, perform a wide-lane (WL) combination of the first carrier-phase measurement and the second carrier-phase measurement and determine whether the GNSS correction data includes an error based at least in part on whether a difference between a float ambiguity value for the WL combination and a closest integer exceeds a threshold value.

Abstract: Techniques for precise positioning using differential carrier phase (DCP)-based measurement updates are disclosed. The techniques can include obtaining a pseudorange observation for a positioning epoch and a carrier phase observation for the positioning epoch based on measurements of global navigation satellite system (GNSS) signals transmitted by one or more space vehicles (SVs) of a GNSS constellation, generating a differential carrier phase observation for the positioning epoch based on the carrier phase observation for the positioning epoch and a determination that real-time kinematic (RTK) correction data associated with the GNSS constellation is unavailable, and generating a position, velocity, and time (PVT) observation of the mobile device for the positioning epoch based on the differential carrier phase observation for the positioning epoch.

Abstract: Techniques for extended wide-lane carrier phase availability using inertial measurement unit (IMU) feedback are disclosed. The techniques can include determining an IMU-based position differential based on first IMU data received from an IMU of the mobile device, detecting a wide-lane cycle slip based on a wide-lane differential carrier phase (DCP) measurement and the IMU-based position differential, responsive to detecting the wide lane cycle slip, adjusting the wide-lane DCP measurement based on the IMU-based position differential to obtain a corrected wide-lane DCP measurement, and generating a global navigation satellite system (GNSS)-based positioning estimate for the mobile device based on the corrected wide-lane DCP measurement.

CPC classification number: G01S19/01 , G01S5/0027
Abstract: Position, Velocity, and Time (PVT) information of a LEO satellite can be determined by leveraging a known position of a mobile device comprising a terrestrial satellite receiver of the LEO satellite and using range information (range and/or range rate) of the LEO satellite taken at the mobile device. According to some embodiments, this PVT information can be shared by the mobile device with the server and/or other mobile devices, and information from multiple mobile devices can be crowdsourced to determine robust PVT information for a LEO satellite. Once the PVT information is determined, it can be used to subsequently for positioning of the mobile device and/or other mobile devices.

Abstract: This disclosure provides systems, methods, and apparatuses for adjusting an encoding timing or a decoding timing in a manner that minimizes disruption of ongoing uplink or downlink traffic. Some aspects more specifically relate to decoupling adjustment of the encoding timing and adjustment the decoding timing to enable independent adjustment of the encoding timing or the decoding timing. In some aspects, a user equipment (UE) may perform adjustment of the encoding timing, relative to an active time indicated by a discontinuous reception (DRX) configuration, at a time at which uplink traffic is absent. Additionally, or alternatively, the UE may perform adjustment of the decoding timing, relative to an active time indicated by a DRX configuration, at a time at which downlink traffic is absent. Accordingly, upon receiving a DRX configuration, the UE may wait until a period in which uplink traffic or downlink traffic is absent to perform a timing adjustment.

Abstract: Global Navigation Satellite System (GNSS) receivers can provide more accurate positioning when augmented using Real-Time Kinematic (RTK) or Differential GNSS (DGNSS) corrections. Techniques described herein leverage multi-constellation, multi-frequency (MCMF) measurements taken at a base station at first and second times to generate correction information that can be used to detect and correct a bias (or offset) in the location of the base station. This bias may be detected by a rover station, or by the base station itself.

Abstract: A device may use Precise Point Positioning (PPP) correction information to generate Real Time Kinematic (RTK) correction information that can be sent to other devices for RTK-based positioning. In particular, according to some embodiments, the first device having access to PPP correction information may obtain the PPP correction information and generate RTK correction information by determining a virtual RTK base station location and generating, based on the PPP correction information, a virtual Multi-Constellation Multi-Frequency (MCMF) measurement corresponding to the determined virtual RTK base station location. This virtual MCMF measurement (and/or data derived therefrom) can then be sent to other devices as RTK correction information.

Abstract: Described are methods, systems, and devices for correcting ionospheric error. In some aspects, a mobile device equipped with a Global Navigation Satellite System (GNSS) receiver is configured to determine a positioning measurement of a GNSS signal. The mobile device is further configured to receive augmentation data from an augmentation system. When augmentation data for a current measurement period is unavailable, the mobile device can obtain augmentation data associated with Total Electron Content (TEC) values (e.g., vertical TEC values) during one or more prior measurement periods. Based on the augmentation data associated with TEC values during one or more prior measurement periods and a pierce point of the received GNSS signal, an ionospheric error in the positioning measurement of the GNSS signal can be determined and corrected.

Abstract: An Real-Time Kinematic (RTK) and/or Differential GNSS (DGNSS) system is disclosed in which correction data from a plurality of reference stations is provided to the mobile device. A selection of reference stations (from which correction data is provided to the mobile device) can be made based on factors such as the approximate location of the mobile device, geometry of the reference stations, and/or other factors. The mobile device can combine the correction data from the plurality of reference stations in different ways to determine an accurate position fix for the mobile device, without interpolating correction data from the plurality of reference stations.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.
