Abstract: Aspects presented herein may enable a UE to perform positioning using virtual anchors and/or positioning reference units. In one aspect, a UE transmits a request for assistance data for performing UE-based positioning, where the request includes at least one of location information of the UE or a list of anchors observed by the UE. The UE receives the assistance data for the UE-based positioning, where the assistance data includes a list of virtual anchors and a list of positioning reference units (PRUs) that includes a set of virtual PRUs (VPRUs), where the list of virtual anchors and the list of PRUs are selected based on at least one of the location information of the UE or the list of anchors observed by the UE. The UE performs the UE-based positioning using at least one virtual anchor and at least one VPRU in the assistance data.

Abstract: In some implementations, a device may obtain first set and second sets of pseudoranges for each of a user equipment (UE) and a reference station, corresponding to first second times, wherein the UE is within a threshold distance of a reference station at the first and second times. Each of the first and second sets of pseudoranges comprise a pseudorange from each of first and second low-earth orbit (LEO) satellites at respective first and second times. The second time is at least a threshold duration after the first time. The device may determine a UE location estimate based at least in part on: the first and second set of pseudoranges, and for each of the first and second times, a respective location of (i) each of the first and second LEO satellites, and (ii) the reference station. The device may output an indication of the location estimate.

Abstract: Techniques are provided for integrating GNSS measurements between two or more GNSS receivers. An example method includes determining an antenna baseline vector based on relative locations of a first antenna that is communicatively coupled to a first GNSS receiver and a second antenna that is communicatively coupled to a second GNSS receiver, determining a first position estimate and a first integer ambiguity resolution (IAR) status with the first GNSS receiver at a first time, determining a second position estimate and a second IAR status with the second GNSS receiver at approximately the first time, computing a horizontal offset value based on the antenna baseline vector and a difference between the first position estimate and the second position estimate, and generating the wrong fix indication in response to the first IAR status being fixed, the second IAR status being fixed, and the horizontal offset value being greater than a threshold value.

Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.

Abstract: A global navigation satellite system (GNSS) device may receive GNSS correction data and may determine a respective standard deviation of pre-fit residuals of one or more GNSS measurement types of a set of GNSS measurements. The GNSS device may determine at least one conditional trigger is met based on a comparison of the respective standard deviation of pre-fit residuals of the one or more GNSS measurement types with a respective threshold, and, responsive to determining the at least one conditional trigger is met, may modify how a positioning engine processes one or more measurements of the set of GNSS measurements. The GNSS device may determine a position estimate of the GNSS device based at least in part on a result of the modified processing of the one or more measurements by the positioning engine and the GNSS correction data.

Abstract: A method for wireless communication at a GNSS is described herein. The method includes obtaining a set of SSR error correction components associated with a set of SVs, where the set of SSR error correction components includes a first number of SSR error correction components that is less than a second number of SSR error correction components in a full set of SSR error correction components. The method includes generating, based on the set of SSR error correction components, (1) an OSR of GNSS measurements associated with the set of SVs and (2) an OSR uncertainty value for the OSR. The method includes computing, based on the OSR of the GNSS measurements and the OSR uncertainty value, a position of the GNSS wireless device. The method includes outputting an indication of the position of the GNSS wireless device.

Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity determines an expiration time for applying correction data to positioning measurements of one or more transmission points (TPs), applies the correction data to one or more positioning measurements obtained by a user equipment (UE) of the one or more TPs before expiration of the expiration time to determine one or more corrected positioning measurements, and determines an estimate of a location of the UE based, at least in part, on the one or more corrected positioning measurements.

Abstract: In some implementations, one or more devices may obtain measurement information for an epoch, the measurement information indicative of a pseudorange measurement, a carrier phase measurement, and a doppler measurement performed by a reference global navigation satellite system (GNSS) receiver of radio frequency (RF) signals transmitted by a plurality of GNSS satellites. The device(s) may obtain initial state-space representation (SSR) data comprising orbit correction, clock correction, and code bias information for the epoch. The device(s) may determine ionospheric correction data for the epoch based on the measurement information and the initial SSR data. The device(s) may determine tropospheric correction data for the epoch based on the determined ionospheric correction data, the measurement information, and the initial SSR data. The device(s) may provide the expanded SSR data, wherein the expanded SSR data includes the ionospheric correction data and the tropospheric correction data.

Abstract: A Precise Positioning Engine (PPE) may use correction information to perform highly accurate Global Navigation Satellite Systems (GNSS) positioning. Transitioning between, or “swapping,” of a first correction information source (e.g., Real-Time Kinematic (RTK) base station) with a second correction information source may be handled using correction information from the first correction information source to update a first state of the PPE. The updated PPE can then be modified by initializing at least ambiguity values of the PPE state. Correction information from the second base can be used to further update the PPE to a second state without a time update at the PPE. By employing this process, embodiments can reduce sudden changes in position estimation due to correction information source swapping, which can often result in resetting of the PPE and a reduced user experience quality.
