Methods, systems, computer-readable media, and apparatuses are described for reporting, in support of positioning a UE, information about consistencies of positioning reference signal (PRS) measurements, PRS resources, PRS resource sets, or transmission and reception points (TRPs). In some embodiments, a UE receives PRS resources from TRPs and performs PRS measurements based on the PRS resources. The UE determines whether certain PRS measurements, PRS resources, PRS resource sets, or TRPs contribute to a consistent position estimate and/or consistent positioning measurements. The UE reports to a device, such as to a location server, information about consistent groups, where each consistent group identifies a set of such consistent elements.

There is disclosed a system for locating an object on a surface waveguide. The surface waveguide is made of one or more 1D wires and/or 2D waveguides comprising conductive elements arranged in patterns. Emitters with known positions can couple with receivers coupled with the surface waveguide. The position of receivers can be determined, for example by multilateration or signal strength indication. Conductive elements can be sprayed or sewed or otherwise deposited onto surfaces such as a ground floor, a sidewalk or a road lane. Described developments comprise the use of absorbers, protective layers, unidirectional emitters, contactless coupling, and various arrangements comprising frequency-selective layers, arrangements in lattices, trellis or anisotropic surfaces. Signal processing aspects and software embodiments are also described.

Embodiments of this application provide a measurement reporting method and apparatus, to resolve a problem that information about a measurement quantity change in a reporting periodicity is lost during measurement reporting in a current technology. The method includes: In a measurement reporting periodicity, a first communication device receives N reference signals sent by a second communication device in N reference signal periodicities, and measures the N reference signals to obtain M measurement values. The first communication device reports a measurement report of M measurement results to a positioning device, where N is an integer greater than 1, and M is less than or equal to N. The first communication device may be a terminal, and the second communication device is a base station. Alternatively, the first communication device may be a base station, and the second communication device is a terminal.

This disclosure describes systems, methods, and devices related to passive location measurement in wireless communications. A device may perform a ranging measurement with a first device and a second device. The device may identify a first uplink (UL) location measurement report (LMR) received from the first device. The device may identify a second UL LMR received from the second device. The device may cause to send a first broadcast LMR comprising information associated with the ranging determination of the first device and the second device. The device may cause to send a second broadcast LMR comprising the measurement information carried in the first UL LMR and the second UL LMR.

The present teaching relates to apparatus, method, medium, and implementations for initiating sensor calibration. A first GPS signal is received by a GPS receiver residing in an ego vehicle and is used to determine a first geo-position of the ego vehicle. A GPS related signal transmitted by a fiducial marker is received and is used to obtain a second geo-position of the fiducial marker. A distance between the ego vehicle and the fiducial marker is determined based on the first and second geo-positions and is used to determine whether to initiate calibration of one or more sensors using the fiducial marker.

Aspects of the present invention provide systems and methods for distributed signal processing of indoor localization signals wherein statistical algorithms and machine learning are used in place of a fingerprint map. The disclosure relates to calculation of angle and distance based on measurements of an indoor localization signal, followed by energy-efficient distribution of signal processing. Local signal processing is performed using any of multiple eigen structure algorithms or a linear probabilistic inference, before cloud-based signal processing is performed using a nonlinear probabilistic inference and machine learning that's been trained with historical data transmitted by the base stations and time-of-day location patterns. Without having to generate and constantly update an energy-exorbitant fingerprint map, the disclosed system reduces localization error to merely 50 cm with 95% probability without compromising energy-efficiency to rival the accuracy of indoor localization systems that utilize fingerprinting.
