摘要： A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.

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。

摘要： Disclosed is a method for establishing a wireless link key between a remote device and a group device. In the method, the remote device obtains a group identifier from the group device, and determines whether the group device is associated with a group having a trust association with the remote device. When the group device is determined to be associated with a group having an established trust association with the remote device, the remote device forwards a link setup request to the group device for virtually pairing with the group device using the trust association to establish the wireless link key. When the group device is determined not to be associated with a group having an established trust association with the remote device, the remote device forwards a pairing request to the group device for pairing with the group device to establish the wireless link key.
