摘要： This disclosure describes systems, methods, and devices related to null data packet (NDP) frame format. A device may cause to send a null data packet announcement (NDPA) frame to a responding station device (RSTA). The device may cause to send a first sounding NDP frame comprising one or more fields formatted to support 2.4 gigahertz (GHz) and 5 GHz bands in a non-trigger-based ranging measurement with the RSTA. The device may identify after a passage of a short inter-frame space (SIFS) time a second NDP frame received from the RSTA. The device may identify a location measurement report frame from the RSTA.

摘要： This disclosure describes systems, methods, and devices related to tone mapping for a high-efficiency (HE) trigger-based (TB) null data packet (NDP) feedback physical layer protocol data unit (PPDU). A device may identify a frame received from a second device. The device may determine, based on the frame, a resource unit allocated to the device, wherein the resource unit is associated with a 20 MHz sub-channel of a bandwidth. The device may determine, based on the resource unit and the bandwidth, tones associated with a HE short training field (HE-STF) of a HE TB NDP feedback PPDU. The device may send the HE TB NDP feedback PPDU to the second device in the 20 MHz sub-channel, wherein the HE TB NDP feedback PPDU includes the tones.

摘要： This disclosure describes systems, methods, and devices related to low latency preemption. A device may divide a first PPDU into a plurality of segmented PPDUs. The device may insert a plurality of time gaps between the plurality of segmented PPDUs, wherein the plurality of time gaps enable preemptive opportunities by a low latency transmitter. The device may identify a preemption request from a low latency transmitter of the one or more station devices during a first time gap between a first segmented PPDU and a second segmented PPDU. The device may preempt the second segmented PPDU based on a preemption bit in order to allow the low latency transmitter to transmit its low latency data.
