    Abstract: Methods and systems for next generation Wi-Fi are disclosed. In one aspect, a method includes encoding, by an electronic device, a preamble, the preamble comprising: a green-field short training field, a first long training field, a second long training field, and a high efficiency signal A field following the short training field the first long training field and the second long training field. The method also includes encoding, by the electronic device, a frame comprising the preamble and data, and transmitting, by the electronic device, the frame over a wireless network. In some aspects, a relative polarity of the first and second training fields indicates whether the frame is a multi-user frame or a single user frame. In some other aspects, the high efficiency signal A field indicates, via an indicator having a predetermined value, whether the frame is a single user frame or a multi-user frame.

    Abstract: An apparatus of a wireless device and related method decode a physical layer convergence protocol (PLCP) protocol data unit (PPDU) preamble comprising a short training field (STF) and a legacy long training field (L-LTF). The STF comprises an orthogonal frequency-division multiplexing (OFDM) quantity of symbols that is dependent upon whether the PPDU comprises a legacy short training field (L-STF) or an extended range short training field (ER-STF). When the STF is an L-STF, the STF comprises 10 OFDM symbols. When the STF is an ER-STF, the STF comprises 10+N OFDM symbols with N > 0. The apparatus decodes an automatic gain control (AGC) setting signal to produce an AGC setting, and utilizes a plurality of the STF OFDM symbols that includes a 10th OFDM symbol when the STF is an L-STF, and a 10+Nth OFDM symbol when the STF is an ER-STF to provide energy for packet detection.

    Abstract: Apparatuses, computer readable media, and methods for addressing for short feedback. An apparatus for address for short feedback including processing circuitry configured to decode a trigger frame (TF) for a null data packet (NDP) feedback report poll, the TF comprising user information fields, wherein the user information fields indicate ranges of association identifications (AIDs), and where the TF further comprises a feedback type field, the TF received from an HE access point. The processing circuitry may be further configured to determine whether the TF indicates that the HE station is scheduled for an NDP feedback report response based on the range of AIDs indicated by the user information fields.

    Abstract: For example, an apparatus may include circuitry and logic configured to cause a wireless communication station (STA) to determine a plurality of uplink (UL) sounding groups of STAs; transmit at least one trigger frame to at least one UL sounding group of the plurality of UL sounding groups to trigger a measurement procedure with the UL sounding group, the trigger frame including one or more Identifiers (IDs) to identify one or more STAs of the UL sounding group; to receive one or more UL Null Data Packet (NDP) sounding frames from the one or more STAs of the UL sounding group in response to the trigger frame; to transmit a downlink (DL) NDP Announcement (NDP-A) frame to the plurality of UL sounding groups; and to transmit a DL NDP sounding frame to the plurality of UL sounding groups.

    Abstract: An apparatus of a wireless communications device to transmit a sounding announcement frame (SAF) for use in a round-trip estimation to a receiving station, and associated method are provided. The apparatus is configured to encode an encoded field of the SAF that is one of a frame control field (FCF) or a sounding dialog token field (SDTF) of a null data packet announcement (NDPA) packet that forms the SAF to indicate to the receiving station that a communication different from a trigger frame may follow. The apparatus is also configured to configure the wireless device to transmit the NDPA packet to one or more stations.

    Abstract: An apparatus and related method of a wireless device are provided to encode or decode one or more indication bits in a high-efficiency signal A (HE-SIG-A) field in a preamble of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to indicate a backup mode that is a 4x long training field (LTF) with 0.8 µs cyclic prefix (CP) mode. One or more indication bits is selected from a Doppler bit, a dual carrier modulation (DCM) bit, a space-time block coding (STBC) bit, and a transmit beamforming (TxBF) bit. The PPDU is transmitted to or received from another wireless device.

    Abstract: Methods, apparatus, and computer-readable media are described to encode a trigger frame for a second station (STA2). A first sounding frame for the STA2 is generated. The first timestamp is associated with a transmission of the first sounding frame. A second sounding frame from the STA2 based upon the first sounding frame is decoded. The second sounding frame includes a holding time indication associated with a second timestamp and a third timestamp. A fourth timestamp is associated with receiving the second sound frame. The holding time indication is protected. A round-trip time is calculated based upon the first timestamp, the holding time indication, and the fourth timestamp.
