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.
