Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

Abstract: A Precise Point Positioning (PPP) system is disclosed in which one or more Global Navigation Satellite System (GNSS) signals are obtained by a mobile device. The mobile device can obtain position information based on one or more position sources, where the position information is indicative of a location of the mobile device. One or more PPP positions of the mobile device can be determined based on the position information and the one or more GNSS signals, where a position uncertainty of the position information meets or is below an uncertainty threshold. A determination of whether at least one PPP position meets or is below one or more convergence thresholds can be made. In response to determining that at least one PPP position meets or is below the one or more convergence thresholds, the at least one PPP position can be provided.

Abstract: Disclosed are various techniques for wireless communication. In one aspect, a user equipment (UE) may receive, from a satellite vehicle (SV), a signal of a first frequency band, estimate a first ionospheric delay residual error based on the signal of the first frequency band, calculate a first pseudorange measurement and a first carrier phase measurement based on the first ionospheric delay residual error, and estimate a position using the first pseudorange measurement and the first carrier phase measurement. In some aspects, the ionospheric delay residual error is estimated via a Klobuchar equation. In some aspects, the position is estimated using ultra-long baseline real-time kinematics (RTK) positioning.

Abstract: A method of registering a target device includes: receiving a first indication to initiate a registration; and determining a suggested registration location and/or or a suggested registration name. The method further includes: providing a second indication of at least one of the suggested registration location or the suggested registration name; providing a third indication requesting at least one of whether the suggested registration location is accepted or whether the suggested registration name is accepted; receiving a fourth indication indicating at least one of whether the suggested registration location is accepted or whether the suggested registration name is accepted; and registering the target device by storing target device information based on the fourth indication.

Abstract: Method, mobile device, computer program product, and apparatus for performing Fine Grain Position Data Collection is described. In one aspect a mobile device performs measurement batching of data, for example positioning and AP measurement data. In some aspects, the mobile device processes positioning and AP measurement data in response to a batch trigger. The mobile device may send the processed measurement batch to a server for analysis or processing. A batch trigger may include receiving a positioning fix with high confidence such that the mobile device may backfilter or otherwise correct mobile sensor based positioning data associated with AP measurements. The server may interpret the data from the measurement batches identified from a number of different mobile devices to calculate position of APs within an environment.

Abstract: Techniques for publishing location information associated with a non-geotagged transceiver are disclosed. A method for publishing a position of a non-geotagged transceiver in a wireless communication system includes determining a first position of the non-geotagged transceiver based on a periodic neighbor list, determining a second position of the non-geotagged transceiver based on an accumulated neighbor list, determining if the first position and the second position agree, publishing a third position if the first position and the second position agree, such that the third position is determined based on the union of the periodic neighbor list and the accumulated neighbor list, and resetting the accumulated neighbor list if the first and second position do not agree.
