Abstract: A wireless device may coordinate UWB channel usage with neighboring devices. In some embodiments, an initiator may periodically send an ultra-wideband acquisition packets (UWB-AP). The UWB-AP may comprise information of future UWB channel usage of the initiator. Neighboring UWB devices may receive the UWB-AP and adjust channel usage based on the UWB-AP.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for passive beacon communication techniques. Transmitting devices (e.g., beacons) can transmit advertising messages using a first wireless protocol to provide timing for ranging messages for one of more ranging messages over a second protocol (e.g., UWB). One or more receiving devices can determine using signal strength if the devices are within a threshold range to perform communication techniques. Various ranging communications techniques can be used to determine a range between the receiving device and transmitting device. Other techniques can be used to passively calculate the angle of arrival for transmitter signals. The angle of arrival information can be used for precise position locating for the receiving device or to indicate interest in information provided by the one or more transmitting devices.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, or a non-transitory computer readable medium storing code or instructions executable by one or more processors) for many-to-many communication techniques for coordinating communications among a group of mobile devices that can be performed by a first mobile devices. The first mobile device can transmit a request to establish outgoing pairwise ranging sessions with other mobile devices of the group. Each of the mobile devices of the group of mobile devices can establish ranging sessions with the other mobile devices. Each mobile device can act as both an initiating device and a responding device for the ranging session. The first mobile device can detect one or more redundant ranging sessions the mobile devices. The first mobile device can identify whether to keep or terminate each of the one or more redundant ranging sessions based on a common criterion.

Abstract: An electronic device may use information about the location of nearby devices to make sharing with those devices more intuitive for a user. The electronic device may include control circuitry, wireless circuitry including first and second antennas, and motion sensor circuitry. The control circuitry may determine the location of a nearby electronic device by calculating the angle of arrival of signals that are transmitted by the nearby electronic device. To obtain a complete, unambiguous angle of arrival solution, the electronic device may be moved into different positions during angle of arrival measurement operations. At each position, the control circuitry may calculate a phase difference associated with the received signals. Motion sensor circuitry may gather motion data as the electronic device is moved into the different positions. The control circuitry may use the received antenna signals and the motion data to determine the complete angle of arrival solution.

Abstract: Methods and devices are provided for allowing a mobile device (e.g., a key fob or a consumer electronic device, such as a mobile phone, watch, or other wearable device) to interact with a vehicle such that a location of the mobile device can be determined by the vehicle, thereby enabling certain functionality of the vehicle. A device may include both RF antenna(s) and magnetic antenna(s) for determining a location of a mobile device relative to the vehicle. Such a hybrid approach can provide various advantages. Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.

CPC classification number: G01S19/29
Abstract: A system and method of continuous carrier wave reconstruction includes a radio navigation receiver that includes one or more processors, memory coupled to the one or more processors, and an input for receiving a signal from a transmitter. The signal has a phase. The one or more processors are configured to obtain phase lock on the received signal, extract first phase information from the received signal, detect a loss in phase lock on the received signal, and extrapolate second phase information while phase lock is lost using a model of the phase. In some embodiments, the one or more processors are further configured to reconstruct the carrier signal based on the first and second phase information. In some embodiments, the one or more processors are further configured to scale the first and second phase information from a first nominal frequency of the received signal to a different second nominal frequency.

Abstract: An electronic device may receive a first signal from a first transmitting device at a first time. The electronic device may receive a second signal from a second transmitting device at a second time. The electronic device may access location information for the first transmitting device and the second transmitting device. The electronic device may receive a message from a second electronic device having a known distance relationship to the first transmitting device and the second transmitting device, wherein the second electronic device is configured to receive the first signal, the second signal, and the message including timing information of the signals. The electronic device may determine the position of the electronic device using the location information and the timing information, wherein the position is dependent on the known distance relationship.

Abstract: In some aspects, a mobile device may receive, from a transmitting device, the signal by a plurality of antennas. The mobile device may measure one or more phase differences among the signal received at the plurality of antennas. The mobile device may determine a first set of possible values for the angle of arrival that are consistent with the one or more phase differences. The mobile device may measure one or more signal values using one or more sensors of the mobile device. The mobile device may for each of the first set of possible values, determining a confidence score based on the one or more signal values. The mobile device may select, based on the confidence scores, one of the first set of possible values as the angle of arrival.
