Abstract: A wireless dockee or a wireless docking center may utilize a fine timing measurement procedure to determine propagation times for signals communicated between the devices. Based on the propagation time, the wireless dockee or the wireless docking center may calculate their proximity to each other. When the proximity supports a wireless docking session, the wireless dockee or the wireless docking center may initiate a wireless docking session. The wireless docking session may include docking the wireless dockee to the wireless docking center and/or undocking the wireless dockee to the wireless docking center.

Abstract: Methods, systems, and devices are described for a wireless positioning framework in which an access point (AP) broadcasts a message within a beacon interval that identifies a transmission schedule for a set of stations. The message may include an information element identifying the stations in the set. The set may be determined based on station clock drifts and/or a ranging accuracy sought by the AP. The AP may also provide a station identifier, and frame spacing and delay parameters, which may be used to determine a distinct backoff for each station. Using distinct backoffs allow the stations to avoid collisions when sending the transmissions. The AP may receive the transmissions according to the identified schedule and may determine a range (e.g., round-trip time) for each station in the set based at least on a time at which the respective transmission is received.

Abstract: Disclosed embodiments facilitate wireless channel calibration, including ranging and direction finding, between wirelessly networked devices. In some embodiments. a method on a first station (STA) may comprise: transmitting a first NDPA frame to one or more second stations (STAs), the first NDPA frame comprising a first bit indicating that one or more subsequent frames comprise ranging or angular information; and transmitting, after a Short Interval Frame Space (SIFS) time interval, a second frame. The second frame may be one of: a Null Data Packet az (NDP_az) frame with information about a time of transmission of the NDP_az frame, or a Null Data Packet (NDP) frame, or a Beam Refinement Protocol (BRP) frame. The first NDPA frame may be unicast, multicast, or broadcast.

Abstract: Disclosed are methods, systems and devices for obtaining a range between devices based, at least in part, on an exchange of wireless messages. For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages. In one implementation, a message transmitted from a first wireless transceiver device to a second wireless transceiver device may comprise one or more parameters indicative of a range between the first wireless transceiver device and the second wireless transceiver device, or a range between the first wireless transceiver device and a third wireless transceiver device other than the second wireless transceiver device.

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: Apparatuses and methods are disclosed for performing ranging operations between an initiator device and a responder device. The initiator device may transmit, to the responder device, a fine timing measurement (FTM) request frame including a request to estimate angle information for a number of frames exchanged between the initiator device and the responder device and indicating a level of accuracy for the estimated angle information. The initiator device may receive a first FTM frame from the responder device, and may transmit an acknowledgement (ACK) frame to the responder device. The initiator device may receive, from the responder device, a second FTM frame including angle information of the first FTM frame and timing information of one or more of the exchanged frames.
