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.
