    Abstract: Round trip time (RTT) measurements may be obtained from downlink (DL) trigger frame and uplink (UL) Multiple-Input Multiple-Output (MIMO) frame transactions, which can replace and/or complement separate RTT measurements. By implementing such techniques, wireless systems can make access to RTT measurements, and consequently, location determination of access points (APs) within the system, more easily accessible to navigation and/or other applications benefitting from such measurements and determinations.

    Abstract: Described are systems and methods for obtaining synchronization at a clock maintained at a wireless device having a respective clock drift. The wireless device may obtain one or more messages indicating two or more clock errors corresponding to two more access points. The wireless device may then establish communication with an access point corresponding to the smallest clock error of the two or more clock errors by synchronizing the clock maintained at the wireless device based on the smallest clock error.

    Abstract: This disclosure includes systems and methods for determining the location of each of a plurality of STAs of a WLAN where an AP measures the round-trip time (RTT) and the angle of arrival (AOA) to each STA from implicit packet exchange, such as data frame and ACK frame. The AP may then report the RTT and AOA measurements to each STA using a dedicated beacon information element (IE) which multicasts RTT and AOA measurements to the STAs. By employing an additional parameter, namely, angle of arrival AOA, a single AP may compute the two-dimensional location of each associated STA. Further, another beacon IE may multicast mapping of the AIDs to MAC addresses so that the associated STAs can understand such mapping for STAs in a network so that one STA may know the location of other STAs. Encryption may be employed to achieve privacy.

    Abstract translation: 本公开包括用于确定WLAN的多个STA中的每一个的位置的系统和方法，其中AP从隐式分组交换测量到每个STA的往返时间（RTT）和到达角（AOA），例如 数据帧和ACK帧。 然后，AP可以使用将RTT和AOA测量多播到STA的专用信标信息元素（IE）向每个STA报告RTT和AOA测量。 通过采用附加参数，即到达角AOA，单个AP可以计算每个相关STA的二维位置。 此外，另一个信标IE可以将AID多播到MAC地址，使得相关联的STA可以理解网络中的STA的这种映射，使得一个STA可以知道其他STA的位置。 可以采用加密来实现隐私。

    Abstract: Aspects of determining a geographical state of a target through a user device are provided. One method includes identifying at least one target associated with a target device configured to provide position data in a standard reference frame along with corresponding time values, and sending a request for access to geographical state information for at least one target. The method may further include receiving geographical state information associated with the at least one target, and generating a visual identifier of the at least one target based on the geographical state information. The visual identifier may be associated with data captured by an imaging sensor which is functionally coupled to the user device. Systems and apparatuses for determining a geographical state of a target through a user device are further presented.

    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 during sessions. In one implementation, an initiating wireless station may transmit an initial FTM request message to a responding wireless station wherein the initial FTM request message comprising one or more fields indicating a capability of the initiating STA to generate Range Reports.
