    摘要： Some demonstrative embodiments include apparatuses, systems and/or methods of Fine Timing Measurement (FTM). For example, a first wireless station may be configured to transmit an FTM request message to a second wireless station; to transmit a first Non Data Packet (NDP) to the second wireless station; to process an FTM response message from the second wireless station; and to process a second NDP from the second wireless station.

    摘要： Some demonstrative embodiments include apparatuses systems and/or methods of Collaborative Time of Arrival (CToA). For example, an apparatus may include circuitry and logic configured to cause a CToA broadcasting wireless communication station (STA) (bSTA) to broadcast an announcement frame to announce a ranging-to-self sequence of a CToA measurement protocol; to broadcast a first ranging measurement frame of the ranging-to-self sequence subsequent to the announcement frame; to broadcast a second ranging measurement frame of the ranging-to-self sequence subsequent to the first ranging measurement frame; and to broadcast a Location Measurement Report (LMR) frame of the ranging-to-self sequence subsequent to the second ranging measurement frame, the LMR frame including a Time of Departure (ToD) of the first ranging measurement frame.

    摘要： Some demonstrative embodiments include apparatuses, devices, systems and methods of range estimation. For example, a mobile device may include a radio to receive from an Access Point (AP) statistical channel information of a plurality of wireless communication channels in a region covered by the AP; a channel estimator to estimate, based on the statistical channel information, a time of arrival (ToA) of a wireless communication signal from the AP via a line of sight (LOS) channel between the AP and the mobile device; and a range estimator to estimate a range between the mobile device and the AP based on the ToA.

    摘要： For example, a mobile station may process a plurality of frames from a plurality of wireless stations, a frame from a wireless station including a ToD of the frame according to a local clock of the wireless station; process timing synchronization information corresponding to the plurality of wireless stations, timing synchronization information corresponding to the wireless station to indicate one or more synchronization offsets between the local clock of the wireless station and one or more other wireless stations of the plurality of wireless stations; and determine a plurality of ToF measurements between the mobile station and the plurality of wireless stations by determining a ToF measurement between the mobile station and the wireless station based on the ToD of the frame from the wireless station, a ToA of the frame from the wireless station, and at least the timing synchronization information corresponding to the wireless station.

    摘要： Embodiments of an access point (AP), a user station (STA), and a method for range estimation in a wireless network are generally described herein. For example, the AP may encode a common information field of a first trigger frame to include a trigger frame type configured to check the readiness of associated and unassociated STAs. The AP may transmit the first trigger frame to STAs and receive feedback from the STAs. The AP may further encode, based on the feedback, a common information field of a second trigger frame to include one of: a trigger frame type that solicits negotiation packets from associated and unassociated STAs using an association identifier (AID) and a pre-AID; or a trigger frame type that solicits channel sounding packets from associated and unassociated STAs using an AID and a pre-AID. The AP may further transmit the second trigger frame to the STAs.
