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: Methods and apparatus for communicating audio packets with ultra-low latency at high data rates from an audio source device to one or more audio output devices over a wireless personal area network (WPAN) connection, such as via a Bluetooth connection. Latency is reduced by using time-efficient audio coding and decoding, limited retransmissions, reduced time and frequency of acknowledgements, and by combining Bluetooth Classic (BTC) packets for downlink audio and downlink control with Bluetooth Low Energy (BTLE) packets for uplink control, uplink acknowledgements, and inter-device wireless communication. The number of retransmissions and packet concealments per frame cycle can be limited to an upper threshold number to satisfy a low latency requirement.
