Abstract
An apparatus to transmit a fine timing measurements (FTM) request from a first station to a second station. The FTM request including a request for suspending FTM measurements, if a threshold of movement has not been crossed since a last FTM measurement by the second station. The second station transmits in response to the FTM request a response including a motion indication of the second station.
Claims25
An apparatus comprising,
- a memory;
- and
- a processor configured to cause a first station to:
- transmit a fine timing measurements (FTM) request to a second station, the FTM request comprising a request to suspend FTM measurements when a motion threshold has not been crossed since a last FTM measurement by the second station;
- process a received acknowledgment (ACK) from the second station in response to the FTM request;
- and
- process a received FTM frame from the second station, the FTM frame comprising a motion detection field to indicate a motion state of the second station.
An apparatus comprising:
- a memory;
- and
- a processor configured to cause a first station to:
- process a received fine timing measurements (FTM) request from a second station, the FTM request comprising a request to suspend FTM measurements when a motion threshold has not been crossed since a last FTM measurement by the first station;
- send an acknowledgment (ACK) to the second station in response to the FTM request;
- and
- send an FTM response frame to the second station, the FTM response frame comprising a motion detection field to indicate a motion state of the first station.
A computer program product comprising one or more tangible computer readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor of a first station, result in:
- processing a fine timing measurements (FTM) request to be transmitted to a second station, the FTM request comprises a suspend FTM request field and a motion threshold field;
- processing an acknowledgment (ACK) received from the second station in response to the FTM request;
- processing a received FTM frame from the second station, the FTM frame comprising a motion detection field to indicate a motion of the second station;
- and
- suspending FTM measurements when the motion detection field is to indicate a non-motion state of the second station since the last FTM measurement.
