Abstract: In a procedure for determining distance (or angle) between a pair of electronic devices wirelessly connected to one another, a current session may be temporarily suspended on request and thereafter the current session may be resumed. Temporary suspension and resumption of the current session may, for example, eliminate starting a new session between the pair of electronic devices and repeating a determination of parameters that were initially agreed upon in the current session. Temporary suspension of a current session may be signaled wirelessly, by one electronic device to the other electronic device, for example, by setting a specific value in a specific field, to signal that the current session is to be paused now, in a frame or message transmitted from the pausing device to the to-be-paused device. The current session may be resumed without repeating determination of the initially-agreed upon parameters, by transmitting a frame to initiate measurement exchange.

Abstract: Disclosed herein are techniques for timing synchronization between a first wireless device and a second wireless device. The techniques include sending a first message by the first wireless device to the second wireless device, obtaining a first timestamp at the first wireless device by the first wireless device, and receiving, by the first wireless device, a fine timing measurement frame from the second wireless device in response to the first message. The fine timing measurement frame includes at least a part of a second timestamp from the second wireless device. The techniques further include determining by the first wireless device that the first wireless device is not synchronized to the second wireless device based at least partially on the part of the second timestamp and the first timestamp.

Abstract translation: 在用于确定一对无线连接的电子设备之间的距离（或角度）的过程中，当前会话可以根据请求暂时中止，此后可以恢复当前会话。 例如，临时暂停和恢复本届会议可能会消除在该对电子设备之间开始新的会话，并重复确定当前会话中最初商定的参数。 当前会话的暂时中止可以通过一个电子设备无线地通过另一个电子设备来发信号，例如，通过在特定字段中设置特定值来表示当前会话现在要暂停，以帧或 从暂停设备发送到待暂停设备的消息。 可以通过发送帧来启动测量交换，可以恢复当前会话而不重复首先同意的参数的确定。
