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 herein relate to wireless communication using combined channel training and physical layer header (SIG) signaling. Devices that comply with the 802.11ax or High Efficiency WLAN (HEW) standard may generate and transmit packets that include such combined information. The combined information may be beamformed to a receiver device via an OFDM signal, which may be decoded by the receiver device to obtain subsequent data included in the signal. For example, initial training symbols associated with channel training subcarriers in the signal may be detected and used to perform a rough estimate of the channel. The rough estimate may thereafter be refined using data symbols detected from adjacent data subcarriers using the channel training symbols. In this way, data subcarriers may also be used to determine a channel response along with channel training subcarriers. Channel training information may be transmitted with data, such as user-specific information, in a single symbol.

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.
