Implementations described herein provide systems, methods, and devices for vehicle occupant detection based on wireless transmission(s) from one or more wireless transmitter devices (e.g., beacons) located in the vehicle. The wireless transmitter devices can be standalone devices, such as portable low energy beacons, and/or the wireless transmitter devices can be integrated into other components of the vehicle, such as an on-board dash computer or a door handle. The systems disclosed herein receive the wireless transmission and determine transmission metrics associated with the transmission, such as a signal strength value or a transmission angle. A driver status determination and/or a passenger status determination is based on the transmission metrics. A data file converter generates a driver status data file representing the driver status determination and/or the passenger status determination. The driver status data file is sent to an application for which the driver status data file is configured.

A method for positioning reference signal configuration comprises receiving, from a network node, one or more first positioning reference signals in a first PRS configuration; performing one or more first measurements on the first PRS to determine one or more first characteristics of the one or more first PRSs; sending, to the network node, a second PRS configuration determined based on the one or more first characteristics; receiving, from the network node, a third PRS configuration, wherein the third PRS configuration comprises one or more third PRSs having at least one different signal characteristic than the one or more first characteristics of the first PRS; and performing one or more second measurements on the one or more third PRSs. The method provides a dynamic configuration for PRS based on the feedback from the UE and a location node, beamforming configuration, or any requirements for physical layer efficiently.

Systems and methods for improved geolocation in a network are disclosed. An end node may transmit a signal. The signal may be received by a plurality of computing devices. Receipt times of the signal at the plurality of computing devices may be used to determine a location of the end node.

Systems and methods for improving vehicle safety via Augmented Reality (AR) are provided. An example system may obtain sensor data indicative of an environment external to the vehicle and within the vehicle, and analyze the sensor data to determine a location of a vehicle safety indicia relative to the vehicle and a field of view of an occupant of the vehicle associated with an AR viewer. Based upon a comparison of the location of the vehicle safety indicia and the field of view of the occupant, the system may present an indication of the vehicle safety indicia via an AR viewer.

Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.

A real-time location system includes a master beacon device, a plurality of tag devices, a plurality of tag response receptor units, and a distance determination unit. The master beacon device includes a beacon transmission unit, a master clock, and a master storage unit configured to store a master time delay data. Each tag device includes a tag clock, a reception unit, a tag data storage unit, a reference time point, a tag-specific emission time delay data associated to the respective tag device and the reference time point, a calibration and calculation unit, and a tag response emission unit. Each tag response receptor unit includes a receptor clock defining a respective receptor time. The distance determination unit includes a data storage unit and a calculation unit.

Co-channel beacon transmissions are provided with at least one of spectral redundancy and temporal redundancy. A receiver produces a snapshot of a superposition of received co-channel beacon transmissions. Subcarrier demodulation, code nulling, or a Class-C linear minimum-mean-square error (MMSE) operation separates multiples ones of the co-channel beacon transmissions or eliminates inter-symbol interference and inter-subcarrier interference in the snapshot. Receiver operations can be performed at a network user, a network node, or a network operations center.

Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

A detection system tracks assets in a galley of an aircraft. A tracked tape node attached to an asset transmits, at a first interval, a beacon including a unique identifier (ID) of the tracked tape node. One of a plurality of tracking tape nodes, each positioned in a different one of a plurality of asset slots of the aircraft galley, activates a receiver for a first period to receive the beacons and stores the unique ID and a receive signal strength indication (RSSI) of the received beacon in a list ordered on the RSSI. The tracking tape node transmits, at a second interval, a tracking beacon including a tracking ID of the tracking tape node and the list. A mobile device receives the tracking beacons and generates a data structure of assets in the galley. The mobile device compares the data structure to a manifest and graphically indicates discrepancies.

A beacon-based approach guidance system is disclosed. A disclosed method includes digitizing at least one signal received at an antenna array of a receiver of a vehicle to digitized data streams of I and Q samples, the at least one signal received from a beacon, the at least one signal modulated with a pseudorandom code at the beacon, correlating the I and Q samples to a locally generated pseudorandom code of the receiver to recover carrier signals, and calculating, based on relative phase characteristics of the recovered carrier signals, a direction of arrival of the at least one signal from the beacon in a vehicle reference frame.
