In various embodiments, techniques are provided for determining and associating multiple locations with beacons, and estimating a location of an electronic device based on beacons having multiple associated locations. To determine multiple locations of a beacon, observations are grouped into observation clusters, a probability is calculated that each observation cluster accurately describes the beacon, multiple observation clusters are selected as representative of the beacon based on the calculated probabilities, characteristics are derived for the beacon (including multiple locations) based on the selected multiple observation clusters, and at least the multiple locations for the beacon are stored in a reference database. To estimate a location of an electronic device, a list of detected beacons is created, one or more locations are accessed from a reference database for each of the beacons on the list of detected beacons with at least one of the beacons having multiple locations, the locations are grouped into location clusters, a probability each location cluster represents a location of the electronic device is calculated, an location cluster is selected to represent the location of the beacon based on the calculated probabilities, and a location of the electronic device is estimated based on the selected location cluster.

A method includes estimating distances between a user device and an access point based on a series of FTM ranging bursts exchanged between the user device and the access point. The method also includes calculating a variance of the estimated distances and in response to determining that the variance exceeds a threshold, instructing the user device to perform an action that reduces the variance. Other embodiments include a device that performs this method.

A method, apparatus and computer program product are provided to identify a particular wireless communication node of one or more wireless communication nodes as a beamforming node. The method, apparatus and computer program product also restrict use of the particular wireless communication node for positioning purposes relative to another one of the wireless communication nodes that has not been identified as a beamforming node. In relation to restricting the use of a beamforming node for positioning purpose, the use of a beamforming node may be restricted in relation to the generation or updating of a radio map and/or in relation to the determination of a position of a mobile device.

Disclosed are various techniques for wireless communication, and in particular, carrier-phase based positioning. In an aspect, a position estimation entity may obtain a first differential measurement based on measurement of a first set of positioning reference signal (PRS) resources by a first node and measurement of a second set of PRS resources by a second node, wherein the first set of PRS resources are phase-coherent with the second set of PRS resources. The position estimation entity may obtain a second differential measurement based on measurement of a third set of PRS resources by the first node and measurement of a fourth set of PRS resources by the second node, wherein the third set of PRS resources are phase-coherent with the fourth set of PRS resources. The position estimation entity may determine a positioning estimate of a target node based on the first differential measurement and the second differential measurement.

Methods, systems, and apparatuses are provided for deriving cell reference location in a wireless communication system. A method for a UE in the wireless communication system can comprise receiving information of a first reference location of a cell, receiving an assistance information associated with the cell, deriving and/or acquiring a second reference location of the cell based on at least the assistance information, and using the second reference location of the cell to evaluate a location-based event or measurement.

A system that includes a plurality of IoT devices associated with ground equipment items, a plurality of gateways to receive data from the IoT devices, and an application that receives the data from the IoT devices, is used to manage mobile ground equipment within an airport and track flight data to match available, working equipment with turnarounds and/or flights based on flight data requirements, predicted turn time, gate position, required special needs equipment, and working/failed equipment.

Methods and systems for localization within an environment include determining a topology estimate of nodes located in a dynamic indoor environment, based on distances measured between the nodes. Rigid k-core sub-graphs of the topology estimate are generated to determine relative localizations of the nodes. Relative localizations are transformed into absolute localizations to generate a map of positions of the nodes within the environment. A feature of the map is deployed to a device in the environment.

In a wireless information collecting method executed by at least one user terminal device that measures wireless information used in a site survey and a server device that stores the wireless information and performs the site survey, the user terminal device performs a step of periodically measuring a current position and transmitting positioning information indicating the current position to the server device, and a step of measuring the wireless information in accordance with a wireless information measurement number instructed by the server device and transmitting wireless information including a position and time to the server device. The server device performs a step of associating a position of the user terminal device and time with the wireless information and creating and updating a condition map indicating a wireless information measurement number at a position and time at which a site survey is performed, and a step of collating the current position of the user terminal and the time with the condition map and transmitting an instruction for the wireless information measurement number based on the current position of the user terminal device and the time to the user terminal device.

A method for assisting in locating a position of a mobile wireless device includes: obtaining location information of an approximate location of the mobile wireless device; generating an almanac of base stations based at least in part on proximity of locations of the base stations to the approximate location of the mobile wireless device, the almanac of base stations comprising at least one cooperative terrestrial base station that can communicate with the mobile wireless device in at least one mode and at least one uncooperative terrestrial base station capable of bi-directional communications and configured to prevent data and voice communications with the mobile wireless device, the at least one uncooperative terrestrial base station being configured to acknowledge a message received from the mobile wireless device; and providing the almanac of base stations to the mobile wireless device.

A mobile device may receive updates, support and other data from a current data center agent platform. When the mobile device travels to another location the nearest data center agent may be different from the previous agent. A changeover determination must be performed prior to determining whether the new agent should be assigned to the mobile device. One example method of operation may include receiving current location information of the mobile device and identifying a present location of the mobile device and a current service center assigned to the mobile device. The method may also provide determining whether a new service center location at a remote location from the current service center location should be assigned to the mobile device based on predefined assignment criteria.
