需要说明的是，分配测距角色后，发送测距控制帧的设备可以为测距发起者或测距响应者。
结合图4，对于OWR方式，测距时刻信息可以指示N个测距响应者分别对应的发送测距响应帧的时刻(即R1至RN对应的时刻)，以及，可以指示测距响应者对应的发送测距报告的时刻(即MR对应的时刻)。
结合图4，对于SS-TWR方式和DS-TWR方式，测距时刻信息可以指示测距发起者分别对应的发送测距发起帧的时刻(即I1对应的时刻、或I1至IM对应的时刻)、可以指示测距响应者分别对应的发送测距响应帧的时刻(即R1至RN对应的时刻)，以及，可以指示测距发起者或测距响应者对应的发送测距报告的时刻(即MR1对应的时 刻、或MR1至MRM对应的时刻)。对于DS-TWR方式，测距时刻信息还可以指示测距发起者发送测距最终帧的时刻(即F1对应的时刻、或F1至FM对应的时刻)。
需要说明的是，对于SS-TWR方式和DS-TWR方式，不限定是由测距发起者向测距响应者发送测距报告，还是由测距响应者向测距发起者发送测距报告。
结合图4，测距时长信息可以指示OWR方式、SS-TWR方式或DS-TWR方式对应的测距阶段的总时长。测距时长信息还可以指示测距阶段中各个子阶段的时长。
例如，以OWR方式为例，测距时长信息可以指示RCP阶段至RCUP阶段的总时长。测距时长信息还可以指示RCP阶段的时长、RRP阶段的时长、MRP阶段的时长、和/或RCUP阶段的时长。
在SS-TWR方式和DS-TWR方式的RIP阶段，测距发起者分别在I1对应的时刻、或I1至IN对应的时刻，向测距响应者发送测距发起帧，测距发起帧可以包括发送该测距发起帧对应的时间戳。测距响应者接收该测距发起帧后，向测距发起帧中添加接收该测距发起帧对应的时间戳。

在OWR方式的RCUP阶段，如果测距控制消息有更新，可以对测距控制消息进行更新，例如测距控制者可以发送测距控制更新消息(ranging control update message，RCM)。
第一设备采用UWB系统广播发送测距参数，至少一个第二设备的UWB系统接收该测距参数。第一设备的UWB系统与至少一个第二设备的UWB系统之间根据该测距参数，执行RIP阶段、RRP阶段、RFP阶段、和MRP阶段、对应的功能进行测距，之后执行RCUP阶段对测距控制消息进行更新。
由此可见，整个测距过程均由设备的UWB系统执行，然而，UWB技术具有传输速率高、系统容量大、和频谱带宽大等特点，长时间使设备的UWB系统执行复杂的任务，会导致设备的功耗过高。
下面将结合图5-图10对本申请实施例提供的测距方法进行具体阐述。

可选地，测距参数信息还可以包括测距时长信息，具体可参照上述阐述，此处不再赘述。第一设备和第二设备可以根据测距时长信息所指示的时长进行测距。
如此，第一设备采用功耗更低的第一资源向第二设备发送该测距参数，降低占用功耗更高的第二资源的时间，从而可以降低测距过程中的功耗。
在一种可能的设计方法中，本申请实施例提供的方法，还可以包括：S503，第一设备采用第一资源向第二设备发送测距信标帧。相应地，第二设备采用第一资源接收来自第一设备的测距信标帧。
示例性地，结合图6，S603，第一设备的第一通信模组向第二设备的第一通信模组发送测距信标帧。相应地，第二设备的第一通信模组接收来自第一设备的第一通信模组的测距信标帧。

可选地，上述第二设备采用第一资源向第一设备发送标识信息可以在RCFP这一时间段执行。
如此，第一设备和第二设备之间采用功耗更低的第一资源建立个域网，并通过第一资源协商获得测距参数信息，通过第一资源传输测距参数信息，可以降低采用功耗更高的第二资源工作的时间，从而进一步降低功耗。
第一设备与第二设备之间采用第一资源获得测距参数信息后，可以采用第二资源进行测距，如此，可以在不降低测距精度的基础上降低功耗。
可选地，结合图6，本申请实施例提供的方法还可以包括：S606-S607。S606，在第一设备的第一通信模组发送测距控制帧后，第一设备的第一通信模组唤醒第一设备的第二通信模组。S607，在第二设备的第一通信模组收到测距控制帧的情况下，第二设备的第一通信模组唤醒第二设备的第二通信模组。
如此，第一设备与第二设备之间可以采用第二资源进行测距，获得精度较高的测距结果。另外，建立个域网、协商获得测距参数信息以及传输测距参数信息这些功能均由第一通信模组来执行，在此基础上，采用第二通信模组进行测距，第二通信模组不需要建立个域网、协商获得测距参数信息等，可以降低第二通信模组在测距过程中的复杂度，从而提高测距效率。
