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

摘要： Embodiments of an access point (AP) may comprise memory and processing circuitry coupled to the memory, and transceiver circuitry coupled to the processing circuitry. The processing circuitry of the AP may be configured to generate a trigger frame to allocate a center 26 tone RU for an HE-trigger-based PPDU, the center 26 tone RU having an adjacent upper 20 MHz subchannel and an adjacent lower 20 MHz subchannel. In an embodiment, the center 26 tone RU is for a station (STA) and wherein the trigger frame indicates to the STA to transmit a pre-HE-STF preamble on one of the adjacent upper 20 MHz subchannel, the adjacent lower 20 MHz subchannel, or both the adjacent upper and lower 20 MHz subchannels, and configure the wireless device to transmit the trigger frame to the station.

摘要： Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data. An access point station (AP) communicates time-critical ULL data using aggregated MAC Protocol Data Unit (A-MPDU) preemption. When time-critical ULL data for a second associated STA (STA2) becomes available at a medium access control (MAC) layer of the AP during transmission of a physical layer protocol data unit (PPDU) to a first associate station (STA1), the AP may encode the time-critical ULL data in a new A-MPDU subframe for insertion before one of the A-MPDU subframes of the PPDU that has not yet been transmitted. The new A-MPDU subframe may be encoded to include zero-padding to set a size of the new A-MPDU subframe equal to a size of the A-MPDU subframe that has been preempted. The A-MPDU subframes 606 for STA1 may be encoded include a MAC address of the STA1 and the new A-MPDU subframe 608 may be encoded include a MAC address of the STA2.
