A method of finding a direction of an ultra-wide band (UWB) using a difference between antenna beam patterns includes receiving a signal from a target device through at least one antenna configured to form a plurality of different beam patterns, obtaining a channel impulse response (CIR) of the received signal for each of the plurality of beam patterns, and finding the direction of the target device based on the CIR.

Provided are a system and method for coordinating dual wireless communications protocols when implementing a time difference of arrival (TDOA) framework for ranging between nodes. A first of the protocols (e.g., BLE) can be used for transmission of synchronization and TDOA schedules that prescribe synchronization and TDOA frames. The synchronization and TDOA frames can then be executed according to a second of the protocols (e.g., UWB), thus exemplifying an efficiency in energy consumption owing to an absence of transitioning between the first and second protocols transmissions throughout the schedules.

Techniques are provide for neural network based positioning of a mobile device. An example method for measuring a channel in a wireless communication system includes: receiving reference signal information; determining one or more channel frequency responses based on the reference signal information and one or more timing hypotheses; determining one or more channel impulse responses comprising a channel impulse response for each of the one or more channel frequency responses; processing the one or more channel impulse responses with a neural network; and determining an output of the neural network.

In one implementation, a method includes receiving versions of a message from a first satellite-based receiver and a second satellite-based receiver that both received a radio frequency (RF) transmission of the message, the message comprising a self-reported position of a transmitter of the message. The method also includes determining a time difference between a first arrival time of the RF transmission of the message at the first satellite-based receiver and a second arrival time of the RF transmission of the message at the second satellite-based receiver. The method further includes determining a measure of the likelihood that the self-reported position of the transmitter is valid based on the time difference between the first and second arrival times. The method still further includes transmitting an indication of the measure of the likelihood that the self-reported position is valid.

An exemplary communications system includes a first base station and a second base station. The first base station transmits a first signal to the second base station, and the second base station receives the first signal and transmits a second signal in response. The first base station receives the second signal and transmits a third signal in response. A receiving unit of a device receives the first, second, and third signals. The device measures a first delay time between receipt of the first signal and receipt of the second signal, and measures a first round trip time based on receipt of the second signal and the third signal. A second round trip time and a second delay time are determined and a first time difference of arrival is calculated based on the first round trip time, first delay time, second round trip time and second delay time.

The current disclosure discloses a method for determining a location of a user device in an industrial facility. The method includes: transmitting a localization request to a location controller via a first base station; receiving a response message at a second time instance from the first base station; transmitting a timing message to the first base station; transmitting a polling message to a second base station; receiving a second response message at a fifth time instance from the second base station; and transmitting a second timing message to the second base station. The location controller is configured to determine the location of the user device based on transmission time instances and reception time instances associated with the localization request, the polling message, the first and second response messages, and the first and second timing messages.

A control device includes a control unit configured to perform control based on a presence area of a first communication device determined using a signal transmitted and received between the first communication device and at least one second communication device. The control unit performs control related to an operation of a controlled device in accordance with a second presence area when a first presence area determined based on a coordinate position of the first communication device on an arbitrary coordinate system associating the first communication device with the second communication device is inconsistent with the second presence area determined based on a distance between the first and second communication devices.

Methods, systems, and devices for wireless communications are described. A base station may request a user equipment (UE) to report location information for the UE using a specific format. The UE may report the location information to the base station based on the request. The base station may use the location information reported by the UE to determine the location of the UE.

A method includes obtaining signal information based on wireless signals communicated between an electronic device and a target device. The method also includes obtaining motion information based on movement of the electronic device.
