摘要： Methods, apparatuses, and computer-readable medium are described for doing fine timing measurements for one or more stations. A trigger frame is encoded for stations. Uplink null data packets are received. A time of arrival for the UP NDP and a time of departure for a downlink null data packet are determined. The time of arrival and time of departure are encoded into a data packet, such as a downlink null data packet announcement. A wireless device is configured to transmit the data packet to a station.

摘要： Disclosed are methods, systems, devices, and computer readable storage medium to manage a received signal strength of sounding frames at a receiving device. If the received signal strengths vary, an automatic gain control parameter may be more highly influenced by those frames having higher received signal strength. A trigger frame indicates a transmission power of the trigger frame, and a target received signal strength at an access point transmitting the trigger frame. Receiving stations may determine a transmit power for a sounding frame based on the trigger frame. For example, a path loss between the access point and receiving station may be determined based on the transmit power and the received power of the trigger frame. A transmit power for the sounding frame may then be determined, in some aspects, by adding the path loss and the target RSSI value.

摘要： An apparatus of a wireless device may operate with a CSI feedback protocol to encode a first NDP for transmission to another wireless device and store a ToD of the first NDP. The apparatus may further decode a second NDP received from the another wireless device and determine a ToA of the second NDP. The apparatus may decode a measurement feedback packet received from the another wireless device that includes a ToD of the second NDP and a down sampled smoothed channel estimation of a channel between the wireless devices, the channel estimation being based on the first NDP. The apparatus may also derive, based on the channel estimation, a ToA of the first NDP at the another wireless device, and calculate, based on the ToD and ToA values, a RTT between the wireless devices. The apparatus may also estimate, based on the RTT, a distance between the wireless devices.

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.
摘要翻译：一般描述估计STA的AoD的设备和方法。 STA接收并存储由AP以不同角度发送的每个音调的音调和发送角度之间的关联。该关联表明，对于每个角度而言，以角度发送的音调是唯一的。 STA检测在每个音调上发送的符号，确定该音调的强度和时间，并且基于关联以及强度和时间中的一个或两个来估计AoD。每个音调可以具有多个符号和/或每个角度的多个音调，其特性被平均以确定特定音调或角度的适当特性。 STA的位置是根据一个或多个AP的AoD计算的。
