An apparatus obtains a set of radio data comprising signal strength related values for radio signals transmitted by a transmitter with an association of each signal strength related value with a representation of a geographical location. The apparatus applies a frequency transform to the obtained set of radio data to obtain transform coefficients, each transform coefficient comprising a transform index and an associated transform value. The apparatus selects a subset of transform indices having more significant transform values than the remaining transform indices and compresses the transform indices by encoding each transform index exploiting a probability of occurrence of an index value of a respective transform index. The same or another apparatus decodes the compressed transform indices again for use in position operations.

In an aspect, a network component (e.g., BS, server, etc.) obtains measurement information associated with uplink signal(s) from UE(s), with the uplink signal(s) having reciprocity with one or more downlink beams of wireless node(s) (e.g., TRP, reference UE, etc.). The network component determines (e.g., generates or refines) a measurement (e.g., RFFP-P) model based on the measurement information. The network component provides the measurement (e.g., RFFP-P) model to a target UE. The target UE receives at least one signal (e.g., PRS) on the one or more downlink beams from the wireless node(s). The target UE processes the at least one signal (e.g., predicts target UE location) based at least in part on the measurement (e.g., RFFP-P) model.

In accordance with the disclosed approach, positioning server(s) could receive, from mobile devices, information indicating a plurality of GNSS rescue areas, each respective GNSS rescue area of the plurality of GNSS rescue areas corresponding to a respective geographic area visited by a respective one of the mobile devices in which (i) at least one GNSS-based position estimate is or was unavailable and (ii) the respective mobile device had demand for positioning data of at least a particular quality level. Given this, the server(s) could generate a GNSS rescue map representing radio data for the plurality of GNSS rescue areas. In this way, the server(s) could transmit, to a mobile device, an offline radio map representing a subset of the GNSS rescue map, to provide radio data for at least one of the GNSS rescue areas or portion thereof.

An edge device includes a first antenna array that includes a first portion and one or more second portions. The edge device includes control circuitry that senses a surrounding area of the edge device in a first frequency by use of the first portion of the first antenna array. The control circuitry executes beamforming to direct a first beam of radio frequency (RF) signal in a second frequency having a signal strength greater than a threshold to a first user equipment (UE) in motion, by use of the one or more second portions of the first antenna array, where the first frequency is different from the second frequency.

The present invention relates to integrated localization method and apparatus of high accuracy, and estimates a relative position of a moving node, based on motion sensing of the moving node, estimates an absolute position of the moving node, based on a change pattern of at least one signal strength received from at least one fixed node over a plurality of time points, calculates accuracy of the absolute position of the moving node that changes along a movement route of the moving node, and determines a current position of the moving node from at least one of the relative position and the absolute position estimated as such in accordance with the accuracy of the absolute position of the moving node. Accordingly, it is possible to accurately estimate a position of a moving node using a radio signal which not only accurately estimates the position of the moving node even in a change of wireless environment or various route changes but also has almost no change in signal strength over a wide region.

Techniques for calculating a location of a position consumer device is disclosed. In one example, a network server may create a fingerprint map from reference data points. Each of the reference data points may include a recorded geo-location of a position source device and signal measurements taken at that recorded geo-location. By initially estimating an initial position of the position consumer device, the network server may apply one or more threshold values to filter reference data points—candidates for interpolation. The network server may then perform an interpolation on one or more pairs of reference data points to find a pair of reference data points that is collinear with the estimated position of the position consumer device. The location of the position consumer device may then be calculated based upon geo-locations of position source devices that are associated with collinear reference data points.

A method and apparatus are provided for estimating characteristic differences between wireless signals transmitted from the same location in spaced apart frequency ranges. Also provided are a method and apparatus for estimating a combined time of arrival of the wireless signals, using the characteristic differences.

Also disclosed is a method of maintaining a database of characteristic difference information.

An edge device includes a first antenna array and control circuitry that activates a sensing function to sense a surrounding area of the edge device and generates a 3D environment representation of the surrounding area of the edge device.

The control circuitry executes beamforming to direct a first beam of RF signal having a signal strength greater than a threshold to the first UE in motion that is recognized as the valid device, based on the track of the position of the first UE and the generated 3D environment representation for high-performance communication.
