    Abstract: Apparatuses and methods are disclosed that may perform ranging operations between a first device and a second device. The second device transmits an FTM request frame indicating a number of supported non-legacy ACK frame formats, and receives a first FTM frame indicating capabilities of the first device to receive each of the non-legacy ACK frame formats supported by the second device. The second device selects one of the non-legacy ACK frame formats or a legacy ACK frame format based, at least in part, on the indicated capabilities of the first device, and then transmits ACK frames using the selected frame format during the ranging operation.

    Abstract: Disclosed herein are techniques for range measurement between one or more wireless stations (STAs) and a first access point (AP). In various embodiments, the first AP may synchronize a clock of the first AP with clocks of one or more synchronized APs. The first AP may perform a synchronization session with the one or more STAs. The first AP may also transmit one or more Broadcast time-of-departure (TOD) frames to the one or more STAs. Each of the one or more Broadcast TOD frames may include a time of departure of a Broadcast TOD frame from the first AP. A second AP and a third AP of the one or more synchronized APs may also transmit one or more Broadcast TOD frames to the one or more STAs for range and/or position determination.

    Abstract: An access point determines the buffered data for each station of a plurality of stations in a BSS and groups the stations with similar station characteristics. The transmission time to the stations in a group can be apportioned. The groups can be ordered based on station characteristics and a transmission history. A sounding for a group can be performed based on the order. The MU-MIMO transmission for the group can be performed until a first condition is met. If the first condition is met, then the sounding and the MU-MIMO transmission for a next group can be performed, according to the order, until a second condition is met. The first condition can include an apportioned transmission time having expired and/or the buffers for the group being flushed. The second condition can include new data having been buffered by the AP and/or all buffered data having been transmitted.

    Abstract: Methods, apparatus, and computer-readable media for wireless communication may involve techniques for throughput estimation. An expected air time parameter may be used as a parameter for estimating throughput. The expected air time parameter may be indicative of an estimated air time fraction obtainable for communications using an access point (AP), for example, between a wireless station (STA) and the AP. Either the expected air time parameter or an estimated air time fraction determined (e.g., calculated) from the expected air time parameter may be transmitted from the AP to the STA (or other communication device) to allow the STA (or other communication device) to determine an estimated throughput for communications using the AP.

    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.
