A position information providing apparatus for providing present position information to a position notifier apparatus is provided. The position information providing apparatus includes an ultrasonic wave output device for outputting ultrasonic wave and a controller for controlling the ultrasonic wave output device. In accordance with contents of the present position information, the controller sequentially selects a modulation frequency from among multiple detectable frequencies which are detectable by the position notifier apparatus and which are lower than an ultrasonic wave frequency. The controller controls the ultrasonic wave output device so that a maximum value or a minimum value of amplitude of the ultrasonic wave varies with to the selected modulation frequency.

Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations. In yet another aspect, positioning may be supported with shared measurement data units and/or shared assistance data units that may be applicable for different positioning methods.

There is provided an apparatus, said apparatus comprising means for receiving an indication from a base station, at a user equipment having at least one antenna panel, to provide beam reporting information according to one of a plurality of beam reporting formats and providing beam reporting information to the base station according to the indicated beam reporting format.

Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving a plurality of position estimates for a user device; providing the plurality of position estimates as input to a trained machine learning model; and outputting a hybrid position of the user device.

Aspects of the disclosure provide a method for observed time difference of arrival (OTDOA) positioning. The method can include receiving from a serving cell of a first network assistance data for measuring time difference of arrival of positioning reference signals (PRSs) received from a plurality of neighboring cells of a second network, receiving from the serving cell a gap pattern for decoding a master information block (MIB) of a first neighboring cell of the plurality of neighboring cells, or a system frame number (SFN) offset of the first neighboring cell, and determining an SFN timing of the first neighboring cell based on the gap pattern for decoding the MIB of the first neighboring cell or the SFN offset of the first neighboring cell.

The method includes receiving, by the one or more processors, one or more second geographic coordinates via an interface configured to receive geographic coordinates from a ground transmission. The method includes determining, by the one or more processors, that the one or more first geographic coordinates and the one or more second geographic coordinates are inconsistent. The method includes updating, by the one or more processors, a flight plan using the one or more second geographic coordinates when the one or more first geographic coordinates are inconsistent with the one or more second geographic coordinates.

A device is disclosed. In one or more examples, the device may include an antenna to receive a signal encoding timing information for one or more of positioning, navigation, and timing. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Data may be encoded using the either positive-going phases or negative-going phases of the data pulses. The device may include a processor to decode the data at least partially responsive to the phases of the respective ones of the number of data pulses.

A system, computer software and method for collecting, in addition to position data, additional positioning data in a user terminal served by a communication network. The method includes initiating, by generating a message within the user terminal, collection of the positioning data, where the positioning data includes information based on which a physical location of the user terminal is determined; measuring, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message; producing, within the user terminal, measurement reports that include the at least one parameter; selecting, within the user terminal, one or more measurement reports that were generated in response to the message generated by the user terminal; reporting the selected one or more measurement reports to an interface within the user terminal; and transmitting, from the interface, the reported one or more measurement reports to an external server or to the communication network.

A method, for use in positioning a target mobile device, includes: transmitting, to the target mobile device from an apparatus, a message indicating a location offset relative to a reference location of a first anchor wireless-signal transmitter that corresponds to a first wireless-signal transmission, the location offset corresponding to a particular second anchor wireless-signal transmitter of a plurality of second anchor wireless-signal transmitters that correspond to a plurality of second wireless-signal transmissions.

Techniques for exchanging secure FTM messages are disclosed. An example of a wireless transceiver system for providing a secure Fine Timing Measurement (FTM) exchange includes a memory and a processor configured to obtain a initial-secure-token value and a secure-token-response value via an out-of-band signal, generate a FTM Request message including the initial-secure-token value, a transmitter to send the FTM Request message to a responding station, and a receiver to receive a FTM Response message including the secure-token-response value from the responding station, such that the at least one processor is configured to determine a Round Trip Time (RTT) value based at least in part on the FTM Response message.
