Abstract: In an example method, a mobile device establishes a first wireless communications link and a second wireless communications link with a second device, and determines that the second wireless communications link is not connected. Responsive to determining that the second wireless communications link is not connected, the mobile device attempts to reestablish the second wireless communications link with the second device according to a duty cycle that varies based at least on a characteristic associated with the first wireless communications link.

Abstract: An example system includes an application processor (AP), a transceiver associated with a firmware layer and a controller. The controller is configured to perform operations that include receiving data representing a clock synchronization request from a remote device, such as a UWB clock synchronization request. The request is received by the transceiver over a wireless communication link. The controller generates a response to the synchronization request. The response is configured for synchronizing a remote clock of the remote device and a local clock of the mobile device. The controller sends, to the remote device by the transceiver, the response to the synchronization request.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations for selecting a device to prioritize for a high power link. The operations include detecting, in proximity of a mobile device, a first and second available devices. The operations also include establishing a respective connection with each of the first and second available device using a first radio access technology (RAT). Further, the operations include determining, using the respective connections, one or more metrics associated with first available device and the second available device, where the one or metrics comprise a respective angle of arrival at the mobile device corresponding to the first available device and the second available device. Further, the operations include determining, based at least on the one or more metrics, to establish a high power link with the first available device using a second RAT, where the second RAT utilizes more power than the first RAT.

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: Techniques for dynamic slot and anchor allocation include accessing allocation data representing at least one time slot allocated for transmission of a radio frequency signal over a wireless communication channel to a wireless device, assigning the at least one time slot to an anchor of a location system, and causing transmission of the radio frequency signal from the anchor to the wireless device in the at least one time slot.
