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: Today's IEEE 802.11 devices operating in the 2.4/5 GHz bands use a 20 MHz channel as a basic operation unit to maintain coexistence with other 802.11 devices. One exemplary aspect is directed toward using a narrower signal bandwidth (e.g. 2 MHz) in the 2.4/5 GHz bands to reduce transmit/receive power consumption or increase transmission range. However, one problem with introducing a narrow bandwidth signal is how to maintain the coexistence between a legacy IEEE 802.11 device that uses a 20 MHz signal bandwidth and a new IEEE 802.11 device that uses a narrower signal bandwidth.

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: Devices, methods, and media described herein can employ the central 26-tone allocation of 802.11ax for transmission of NB beacons and wake-up packets. Having a dedicated narrowband channel for transmission of NB beacons and/or wake-up packets improves the overall spectrum efficiency. Further, the embodiments may use the central 26-tone subchannel for LP-WUR and legacy IEEE 802.11ax OFDMA transmission, but not for the LP-NB IoT devices that have a OFDM waveform. This configuration reduces the implementation cost and test/certification time & cost of IoT devices.

Abstract: This disclosure describes systems, methods, and devices related to multi-link operation. A device may configure a single N×N transmit (TX)/receive (RX) radio to a plurality of 1×1 TX/RX radios, where N is a positive integer. The device may monitor a first channel of a plurality of channels to determine its availability. The device may monitor a second channel of the plurality of channels to determine its availability. The device may identify a first control frame received from an access point (AP) multi-link device (MLD) on the second channel. The device may cause to send a second control frame to the AP MLD on the second channel. The device may configure back to a single N×N TX/RX radio to receive a data frame.

Abstract: One embodiment is a WUR that not only awakens a Wi-Fi radio in a master device, but also awakens any other radio technology connected to the master device, either directly, or indirectly. These techniques are applicable to any of multiple technologies such as ZigBee, BT, cellular, BLE, Wi-Fi, etc., and in general any wireless communication technology. One embodiment allows one wake-up radio in the master controller to be connected other device(s) within a network, regardless of the radio technology the device(s) use, and allows wake-up of those device(s). One embodiment enables the WUR packet to target device categories/technologies. This extends its use beyond Wi-Fi, and does so in a managed manner which also allows for the WUR payload to be reconfigurable based on the preamble code and/or the information in the first part of the payload, and provides a way to aggregate WUR packets to activate device(s) by a WUR(s).
