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: Some aspects of this disclosure include apparatuses and methods for implementing a synchronized short range communication protocol scan mechanism across multiple devices. Some aspects relate to an electronic device including a transceiver configured to communicate based on a short range communication protocol and a processor communicatively coupled to the transceiver. The processor receives one or more parameters from a peripheral electronic device and determines, based at least on the one or more parameters, one or more synchronization parameters. The processor further transmits the one or more synchronization parameters to the peripheral electronic device. The one or more synchronization parameters can include at least a scan offset associated with the peripheral electronic device.

Abstract: Methods, systems, and apparatuses are presented to utilize Bluetooth (BT) radios to synchronize ultra wideband (UWB) radios, to allow the UWB radios to operate within narrow transmit/receive windows, which may lead to power savings. In some implementations, a transmitting UWB radio and a receiving UWB radio may synchronize the expected time of an UWB transmission based on BT events, such as receiving a BT advertisement, or establishing a BT connection. In some implementations, the transmitting UWB radio and the receiving UWB radio may synchronize the expected time of an UWB transmission based on synchronized event counters maintained by the BT radios. Information regarding UWB transmission start times may also be passed via BT communications, in some implementations.

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: An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface devices.

Abstract: A method is provided. The method includes attaching a user device to a wireless network via a router of a first communications protocol. The method includes determining, based on information about a second session using a second communications protocol, a first time window and a second time window. The method includes determining to perform a first session using the first communications protocol in the first time window. The method includes performing a first arbitration between the first session and the second session. The method includes determining, based on the first arbitration, that the first session has a priority over the second session in the second time window. The method includes performing a second arbitration between the first session and a third session using a third communications protocol. The method includes determining, based on the second arbitration, whether to perform the first session in the second time window.
