An interference detection system in a network identifies a first wireless station that has experienced radio frequency (RF) interference from an unknown source and identifies one or more second wireless stations that have experienced similar interference. A plurality of estimated interference source locations are scored based on a comparison of estimated interference to observed interference at the one or more second wireless stations. A predicted interference source location is identified based on the scored plurality of estimated interference source locations. It is determined whether the unknown interference source is a persistent interference source over a selected time period, wherein the predicted interference source location is identified for each interval in the selected time period. The predicted interference source locations for each interval in the selected time period are retrieved and an aggregated predicted interference source location is calculated based on the retrieved predicted interference source locations.

Disclosed are techniques for wireless communication. In an aspect, an assisting user equipment (UE) receives a request to perform a positioning procedure from a target UE over a sidelink between the assisting UE and the target UE, wherein the assisting UE and the target UE are both out of network coverage, determines, based at least on the request, a set of time and/or frequency resources on which to transmit one or more positioning reference signals for the positioning procedure, and transmits the one or more positioning reference signals to the target UE via the set of time and/or frequency resources.

This problem has been addressed before, but the way of doing so is flawed and incomplete. Only larger objects can be tracked, neglecting items such as glasses, TV remotes, and headphones. Some also solely use Bluetooth tracking, which can be quick and precise, but is unreliable. Items lost far away from people with Bluetooth active their phone cannot be found using this method. This is not an option for most small, easily misplaced items. Various embodiments of the device (in one case using the name SeekR) allow for tracking of all these difficult-to-keep-track-of items. The device's small size allows it to attach to all of these items that existing solutions cannot, e.g., on the frame of glasses, e.g., the bridge, temple and/or temple tips. The device also incorporates assisted global positioning system (AGPS), which is much more reliable than tracking devices that solely use Bluetooth technology, and, in many cases, using AGPS results in identifying the location of a lost item faster than using Bluetooth (or other short distance wireless communication systems). The AGPS system used in various embodiments combines trilateration and global positioning system (GPS) technology to determine a more accurate device location in less time than using GPS systems alone.

The UWB infrastructure has: stationary transmitters emitting the UWB beacon signals into a localizing zone; discovery infrastructure wireless communicating infrastructure data about the UWB infrastructure to the localizing sensor, the discovery infrastructure having a discovery signal transceiver receiving a discovery advertisement signal from the localizing sensor and sending, in response, a provisioning signal with the infrastructure data. A data storage is configured to store the infrastructure data that is required to operate the localizing sensor in the UWB operation mode in accordance with a UWB framing protocol.

This disclosure describes methods and systems for estimating positions of a mobile terminals. The position of a mobile terminal may be estimated based on measured timing information of reference signals transmitted by a plurality of base stations and received by the mobile terminal as compensated by non-line-of-sight (NLOS) delay times in the reference signal propagation times. The NLOS delay times may be estimated using one or more positioning anchors. Alternatively, the NLOS delay times may be estimated by using multiple spatially separate antennas of the mobile terminal, by jointly with other mobile terminals, or by using other approximation methods. The approaches provided by this disclosure facilitate more accurate position estimates for high precision mobile positioning applications.

A system and method for determining the location of a vehicle when GNSS signals are not available use triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the vehicle. The distance between each radio transmitter and/or each radio receiver can be determined according a phase difference between received radio signals. The radio signals can have the geographical location of the radio transmitter included therein. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the vehicle.
