摘要： Embodiments of an access point (AP), station (STA) and method of sounding are generally described herein. The AP may transmit, during a transmission opportunity (TXOP), a trigger frame (TF) to indicate that an STA is to transmit an uplink sounding packet during an uplink sounding period of the TXOP. The AP may attempt to detect the uplink sounding packet during the uplink sounding period. If the uplink sounding packet is not detected during the uplink sounding period, the AP may transmit a recovery packet to cause other STAs to determine a busy condition during the uplink sounding period. If the uplink sounding packet is detected during the uplink sounding period, the AP may determine a channel estimate for the STA based at least partly on the uplink sounding packet.

摘要： Devices and methods of estimating the AoD of a STA are generally described. The STA receives and stores an association between tone and transmission angle for each tone transmitted by an AP in different angles. The association indicates that, for each angle, a tone transmitted in the angle is unique. The STA detects a symbol transmitted on each tone, determines the strength and timing of the tone and estimates the AoD based on the association and either or both the strength and timing. Each tone may have multiple symbols and/or each angle multiple tones whose characteristics are averaged to determine the appropriate characteristic of the particular tone or angle. The position of the STA is calculated from the AoD of one or more APs.

摘要： This disclosure describes systems, methods, and devices related to enhanced crowd-sourcing navigation. A device may identify user information received from the device, the user information corresponding to a trajectory of the device as determined by a navigation system of the device. The device may identify external information corresponding to the trajectory of the device, as determined by a wireless network. The device may determine navigation system error by comparing the user information to the external information. The device may cause to send information associated with the navigation system error to a server.

摘要： Devices and methods of estimating the AoD of a STA are generally described. The STA receives comparison symbols from a first AP antenna. The comparison symbols are received prior to and after switching of transmitter chains from a first set of antennas to a second set of antennas. AoD symbols are received immediately after the comparison symbols. A phase and amplitude correction is determined based on a phase and amplitude change between the comparison symbols and the second AoD symbol corrected based thereon. The AoD is subsequently estimated based on the symbol measurements.

摘要： Embodiments of a communication station (STA) and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, an initiating station may transmit a message M1 carrying a high-throughput control (HTC) field that includes a reverse direction grant (RDG) bit. The RDG indication grants permission to a responding station to send information back to the initiating station. The message M1 may be a timing measurement action frame. An ACK frame may be received from the responding station to acknowledge receipt of the message M1. The ACK frame may optionally carry an HTC field that includes a more PPDU indication to indicate whether a PPDU (e.g., contained in message M2) is to follow the ACK frame. The message M2 may be received from the responding station and may include timing measurement information from a current and/or one or more previous ToF message exchanges.

摘要： The disclosure generally relates to a method and apparatus for using a location token to locate a mobile device in a mapped environment. In one embodiment, the disclosure relates to identifying an AP in the environment using an AP location token. By finding a map from a map vendor which has a substantially identical map token, the AP and the map may be matched together. Once the AP is matched to the map, its exact location will be known. The location of a mobile device may be determined in relation to the AP's location. The same process may be used to identify the location of several APs on a map and thereby identify the location of the mobile device relative to the APs.

摘要： Embodiments of a system and method for Access Point Location Discovery in Unmanaged Networks are generally described herein. When a device attempts to discern its location indoors, it must be aware of the exact location of the network infrastructure that participates in the measurement. Indoors, it is the location of the Access Points (APs), which must be known to the device in order to triangulate its position. A system and method are disclosed for correctly discovering the exact location of network APs. An AP populates a neighbor list with location information by performing Wi-Fi scanning to receive a Media Access Control address and radio channel of a neighboring AP. The interested AP then acquires the position of this AP neighbor by querying its location and receiving its position information. Lastly, the received neighbor location is validated for correctness and reliability using Time of Flight measurements.
