    Abstract: This disclosure describes systems, methods, and devices related to enhanced 60 gigahertz (GHz) preamble. A device may generate a frame for 60 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 modified legacy signal (L-SIG) field comprising one or more subfields for operation in the 60 GHz transmission. The device may generate a modified legacy long training field (L-LTF) for operation in the 60 GHz transmission. The device may utilize 56 subcarriers in the modified L-LTF in the frame. The device may cause to send the frame comprising the modified L-LTF and the modified L-SIG to the one or more STAs.

    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: 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 block acknowledgment (ACK) overhead reduction. A device may receive a soliciting physical layer convergence protocol data unit (PPDU). The device may encode a multiple station device (Multi-STA) block acknowledgment (BA) as a response to the soliciting PPDU. The device may transmit the Multi-STA BA in response to the PPDU. The device may manage multiple Per Association Identification (AID) Traffic Identifier (TID) Information (Per AID TID Info) entries with the same AID and TID in the same Multi-STA BA. The device may set the Per AID TID Info entries with the same AID and TID to be consecutive.

    Abstract: This disclosure describes systems, methods, and devices related to enhanced low latency (LL). A device may establish time gaps between consecutive physical layer (PHY) convergence protocol data units (PPDUs) to optimize preemption opportunities for low latency (LL) transmission by one or more station devices (STAs). The device may identify a preemption request (PR) frame received from at least one of the one or more STAs including unregistered STAs only or including both unregistered and registered STAs during a time gap, indicating an intent to transmit LL packets when preemption is permitted. The device may determine a preemptability of a current transmit opportunity (TXOP). The device may cause to send a preemption indication in a PPDU preceding the time gap.
