摘要： A data source sends a synchronization signal and information to several data sinks that use the synchronization signal and a specified parameter to determine when to process the information. The data source and data sinks may comprise wireless nodes such as, for example, a wireless audio source that sends multi-channel data to a pair of wireless earpieces. The wireless earpieces use the synchronization signal and a latency interval to determine the appropriate time to output audio based on the audio channels.

摘要： Relatively short turnaround times are provided in conjunction with two-way ranging to, for example, facilitate accurate ranging measurements when the relative clock drift between ranging nodes (e.g., devices) is relatively high. In some aspects, relatively short turnaround times are achieved through the use of a symmetric channel that is defined to enable concurrent transmission of ranging messages between nodes. For example, a symmetric channel may be established by configuring the nodes to receive one or more pulses associated with a received ranging message in between pulse transmissions associated with a transmitted ranging message. In this way, one node may send a ranging timestamp shortly after the other nodes sends its ranging timestamp, thereby mitigating the impact of the clock drift on the ranging measurements. In some aspects the pulses may comprise ultra-wideband pulses. The techniques described herein may be employed to provide two-way ranging in, for example, low power and/or non-coherent wireless devices.
摘要翻译：结合双向测距提供相对短的周转时间，例如，当测距节点（例如，设备）之间的相对时钟漂移相对较高时，便于进行准确的测距测量。在一些方面，通过使用被定义为能够在节点之间并行传送测距消息的对称信道来实现相对短的周转时间。例如，可以通过将节点配置为在与传送的测距消息相关联的脉冲传输之间接收与接收到的测距消息相关联的一个或多个脉冲来建立对称信道。以这种方式，一个节点可以在其他节点发送其测距时间戳之后不久发送测距时间戳，从而减轻时钟漂移对测距测量的影响。在一些方面，脉冲可以包括超宽带脉冲。本文描述的技术可以用于在例如低功率和/或非相干无线设备中提供双向测距。
