A system and method for communicating data comprises a group of radios intercommunicating data through a channel using a time division multiple access having a plurality of timeslots. The system further comprises a first radio of the group of radios selecting a data communication selection, said first radio communicating a request control signal to a leader radio of the group of radios. When a request control acknowledge signal is received from a leader radio at the first radio, suspending time division multiple access intercommunicating data within the group of radios using the plurality of timeslots and communicating data through the channel.

Exemplary methods, apparatuses, and systems read location data representing a current location of a mobile device. The location data for the mobile device is taken at a first sampling rate. Upon determining that the location data indicates that the mobile device is approaching a geographic area having a history of wireless communication loss, the mobile device is triggered to increase location data sampling from the first sampling rate to a second sampling rate.

An apparatus has circuitry which determines a location of a user, based on sound data representing speech of the user, and identifies the user based on the determined location of the user and user identification information and location information received from a mobile device.

The present invention provides a method of communicating vehicle positioning information, wherein signals are transmitted from at least one vehicle mounted antenna for indicating a position of the vehicle to another entity, the signals including information concerning at least one of an identity of the at least one antenna and information providing a displacement between the at least one antenna and a boundary of the vehicle.

A method includes obtaining piece(s) of calendar information indicative of at least one appointment taking place in a space and extracting a set of space identifiers representing space(s) of the venue. The space identifier(s) for one or more spaces are extracted based on an indoor map of the venue. The method also includes determining or triggering determining whether at least a part of the set of space identifiers or one or more spaces of the set of space identifiers match(es) the at least one space as represented by the piece(s) of calendar information; and if a match is found: determining one or more reference location estimates. A respective reference location estimate is indicative of a location of the space that was determined to be a match. A corresponding apparatus, computer program product and system are also provided.

Determining, broadcasting and using reference pressure data in a network of transmitters. Particular embodiments described herein include machines that select atmospheric data from weather stations within a transmitter network, use the selected atmospheric data to determine a reference atmospheric value, and transmit the reference atmospheric value from a transmitter to a mobile device for use in estimating an altitude of the mobile device. The atmospheric data may include any of reference pressures form the weather stations, measured temperatures from the weather stations, or reference temperatures from the weather stations. The reference atmospheric value may include a reference pressure value of a reference altitude, or a reference temperature value.

A system and method for autonomous distress tracking of an aircraft. An automatic dependent surveillance-broadcast transceiver is configured to transmit an automatic distress transmission. A system controller comprises a distress identifier that is configured to determine when the aircraft is in a distress condition. The system controller is configured to control the automatic dependent surveillance-broadcast transceiver to transmit the automatic distress transmission in response to a determination that the aircraft is in the distress condition. The automatic dependent surveillance-broadcast transceiver and the system controller are contained within a housing attached to the aircraft on an outside of the aircraft.

A method is disclosed, performed by a first wireless node, such as a wireless device, for enabling positioning of the wireless device. The method comprises providing, to a network node, a measurement report comprising a positioning measurement based on one or more reference signals transmitted from one or more second wireless nodes, such as base stations. The measurement report comprises an indication as to whether the positioning measurement is performed on a Line of Sight, LoS, component of the one or more reference signals.

A UE includes: a transceiver configured to receive positioning signals from a positioning-signal source; a memory; and a processor communicatively coupled to the transceiver and the memory, the processor configured to: measure a plurality of the positioning signals, from a plurality of ports, spanning a collection of Orthogonal Frequency Division Multiplexed symbols to obtain a plurality of multi-port measurements; determine, based on the plurality of multi-port measurements, that a particular effective beam corresponds to an earliest time of arrival from the positioning-signal source to the UE of a plurality of effective beams associated with the plurality of ports; and send, via the transceiver to a first network entity, abeam indication indicative of the particular effective beam.

The prediction control part 204 predicts a three-dimensional position and a three-dimensional velocity of the world coordinate system of the flying ball at a specific time after the initial time as a predicted position and a predicted velocity based on initial position and initial velocity of flying ball, and an equation indicating a parabolic shape of the flying ball. The conversion control part 205 converts the predicted position into a two-dimensional position of a camera coordinate system as a temporary position. The acquisition control part 206 specifies a flying ball image and acquires a two-dimensional position of the camera coordinate system of the flying ball image as an observation position. The correction control part 207 corrects the predicted position and the predicted velocity as a corrected position and a corrected velocity based on the predicted position and the predicted velocity, the observation position, and a Kalman filter.
