    Abstract: This disclosure describes systems, methods, and devices related to extremely high throughput (EHT) trigger based (TB) preamble. A device may receive a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device. The device may generate an EHT physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field. The device may encode the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs. The device may cause to send the PPDU to the AP and an uplink data transmission direction.

    Abstract: This disclosure describes systems, methods, and devices related to enhanced L-SIG. A device may generate a frame for 60 gigahertz (GHz) transmission, the frame comprising one or more fields to carry information associated with one or more station devices (STAs). The device may generate a special legacy signal (L-SIG) field comprising one or more subfields for operation in the 60 gigahertz (GHz) transmission. The device may include the L-SIG field in the frame. The device may cause to send the frame to the one or more STAs.

    Abstract: This disclosure generally relates to methods, systems, and devices for enhanced physical (PHY) layer security. A device may determine a physical layer (PHY) frame to be sent to a station device. The device may identify an encryption seed sequence to be used for encrypting a first portion of the PHY frame. The device may include an indication of the encryption seed sequence in a first field of one or more fields of the PHY frame. The device may encode the first portion of the PHY frame using the encryption seed sequence. The device may cause to send the PHY frame to the station device.

    Abstract: Techniques have been proposed to transmit a wake-up packet at the central 26-tone resource unit of the IEEE 802.11ax OFDMA structure with a low-power wake-up radio packet within the OFDMA allocation. Prior techniques proposed to multiplex transmission of the wake-up packet with IEEE 802.11ax OFDMA PPDUs; leaving the RUs adjacent to the central 26-tone unassigned to function as guard bands. These guard bands are needed to reduce the impact of the adjacent channel interference on the LP-WUR. One embodiment transmits the 26×20 MHz/256=2.03125 MHz wake-up pulse at the center of (or in general anywhere within) the band (e.g., RU5) without requiring the nulling of the seven DC subcarriers. This moves the wakeup pulse inward leaving larger guard bands between the wake-up packet and the adjacent OFDMA allocations. This at least improves the LP-WUR detection performance and will allow assignment of more RUs to IEEE 802.11ax OFDMA PPDUs—Thereby improving overall system throughput and efficiency.

    Abstract: This disclosure describes systems, methods, and devices related to enhanced acknowledgment. A device may identify a physical layer (PHY) convergence protocol data unit (PPDU) received from an Access point (AP), wherein the PPDU comprises a header and a payload. The device may generate a failure of decoding the payload. The device may generate an acknowledgment indicating the failure and indicating additional information to assist the AP in determining a failure reason. The device may cause to send the acknowledgment to the AP.

    Abstract: This disclosure describes systems, methods, and devices related to trigger based duplicate. A device may generate a variant trigger frame comprising one or more fields to carry information associated with multiple station devices (STAs). The device may include scheduling of a transmission of uplink (UL) trigger based (TB) physical layer (PHY) convergence protocol data unit (PPDU) for the multiple STAs. The device may cause to send the variant trigger frame to the multiple STAs.
