    Abstract: A first device may communicate via a first wireless interface (WI) and a second WI, with the second WI operating at a relatively higher power level than the first WI. The first device may receive a scan notification corresponding to wireless scanning performed by a second device. The first device may subsequently perform wireless scanning using the second WI in response to the scan notification indicating that the first device is within effective communication range of a third device. The first device may receive the scan notification over a wireless connection established between the first device and the second device using the first WI. The first device may transmit filter information to the second device, the filter information indicating when, and for which scans the first device is to receive scan notifications. The first device may also activate the second WI and use the second WI to perform ranging and/or control operations associated with the third device.

    Abstract: In order to reduce the power consumption after a transmitting electronic device in a wireless network has been detected, a receiving electronic device calculates transmit times of subsequent beacons from the transmitting electronic device based on a clock drift of the transmitting electronic device and the beacon period. Then, the receiving electronic device receives the subsequent beacon by opening scan windows that encompass the calculated transmit times. However, because the transmit times are more predictable after the transmitting electronic device has been detected (and the clock drift of the transmitting electronic device is known to the receiving electronic device), the receiving electronic device can reduce the width of the scan windows. In addition, the transmitting electronic device can further reduce the power consumption by increasing the beacon period.

    Abstract translation: 为了在已经检测到无线网络中的发送电子设备之后降低功耗，接收电子设备基于发送电子设备的时钟漂移和信标周期来计算来自发送电子设备的后续信标的发送时间。 然后，接收电子设备通过打开包含所计算的发送时间的扫描窗口来接收后续信标。 然而，由于在检测到发送电子设备之后（并且发送电子设备的时钟漂移对于接收电子设备是已知的），发送时间更可预测，所以接收电子设备可以减小扫描窗口的宽度。 此外，发送电子设备可以通过增加信标周期来进一步降低功耗。

    Abstract: An audio output device may join an existing session between a source device and another audio output device. The source device may transmit audio data associated with an audio session, using a first frequency band, to a first wireless audio output device and transmit connection information associated with the audio session to a second wireless audio output device over a second frequency band. The second frequency band differs from the first frequency band and the connection information allows the second wireless audio output device to join the audio session. After transmitting the connection information, the source device may transmit subsequent audio data associated with the audio session to the first wireless audio output device and the second wireless audio output device.

    Abstract: A user equipment (UE) tunes a transceiver of the UE to a first frequency associated with a first channel, transmits a first short packet to a second UE on the first channel and determines whether a first indication was received from the second UE in response to the first short packet. The first indication indicates that the first channel satisfies one or more predetermined criteria. The UE transmits then the primary data to the second UE on the first channel in response to the first indication being received from the second UE.

    Abstract: Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity. In response to determining that the other integrated circuit is authorized to execute the activity, the processor circuit sends, to the other integrated circuit over a configurable direct connection, an authorization signal authorizing the other integrated circuit to execute the activity.
