摘要
This disclosure describes systems, methods, and devices related to EHT training fields. A device may send a trigger frame having a type of HE null data packet (NDP) feedback, wherein the trigger frame requests feedback from a station device (STA) of one or more station device (STA). The device may receive a frame from the STA, wherein the frame comprises an HE long training field (HE-LTF) portion and an HE short training field (HE-STF), wherein the HE-STF is generated in a frequency domain over a first bandwidth. The device may identify that the HE-LTF comprises energy on a set of tones, wherein the set of tones are selected based on feedback status values associated with a resource unit (RU) tone set index. The device may identify that the HE-STF comprises a second set of tones that are energized based on a sequence that is selected based on the first bandwidth used for the frame
