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.

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.

Abstract: Embodiments disclosed herein relate to reducing a power consumption of an electronic device while maintaining some functionality of the electronic device while the electronic device is in a low power mode. The device may be in the low power mode due to a battery level being below a threshold. If the battery level is below the threshold, the electronic device may enter the low power mode. However, before entering the low power mode, some functionality of an application processor may be transferred to a communication controller. Once the functionality is transferred, the application processor may be disabled to reduce power consumption while maintaining functionality of the application processor. The electronic device may also utilize various communication protocols to communicate with a peripheral device. Even though the electronic device may be in the low power mode, the communication controller may be used to cause the peripheral device to perform various actions.

Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

Abstract: A mobile device may receive a plurality of timestamps, wherein the plurality of timestamps indicate sending and receiving time for ranging packets and response packets. The mobile device may calculate a responder turn-around time as a first difference between the second time and the first time. The mobile device may calculate a responding round trip time as a second difference between the second time and the third time. The mobile device may receive from the electronic device an initiator turn-around time and an initiator round trip time. The mobile device may calculate a frequency offset for the wireless protocol using the responder turn-around time, the responding round trip time, the initiator turn-around time, and the initiator round trip time. The mobile device may compare an observed frequency offset to the calculated frequency offset to determine a frequency offset difference and whether it exceeds a threshold, adjusting a ranging measurement.

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 communication techniques between an electronic device (e.g., a smart speaker, a smart TV, a smart appliance, etc.) and one or more mobile devices (e.g., a smartphone, a tablet, a wearable device etc.). Techniques can vary the rate the mobile device responds to ranging messages from the smart speaker based on one or more factors. These factors can include a state of the mobile device (e.g., awake or asleep), mobile device orientation (e.g., face down), application state (e.g., music App active), motion of the mobile device (e.g., at rest for period of time), and a range (distance/angle) between the mobile device and the speaker to conserve battery life. The range to the electronic device can activate one or more smart speaker features on the mobile device.

Abstract: Methods and apparatus to support channel access control for keyless vehicle entry systems are disclosed. An initiating central wireless device of a wireless personal area network (WPAN) queries multiple responding peripheral wireless devices to perform ranging for distance and/or angle of arrival data, where the multiple peripheral wireless devices coordinate responses to minimize interference, avoid overlapping transmissions, and reduce time to complete ranging. Ranging frames are divided into multiple ranging time slots, where each ranging time slot can accommodate a full ranging cycle between the central and peripheral wireless devices. The central wireless device determines which ranging time slot to use based on estimates of communication channel interference and on a number of received responses from the peripheral wireless devices. Ranging measurements are provided to a controller of a vehicle that houses the peripheral wireless devices to determine whether to permit vehicle access.
