Abstract: For example, an apparatus may be configured to cause an Access Point (AP) Multi-Link Device (MLD) to, during an ongoing communication between a first AP of the AP MLD and a first non-AP wireless communication station (STA) over a first wireless communication channel, communicate a suspend request by a second AP of the AP MLD over a second wireless communication channel, the suspend request configured to request suspension of the ongoing communication between the first AP of the AP MLD and the first non-AP STA; to suspend the ongoing communication between the first AP of the MLD and the first non-AP STA over the first wireless communication channel for a suspension period; and to communicate a frame by the first AP over the first wireless communication channel during the suspension period, the frame communicated between the first AP and a second non-AP STA.

Abstract: Methods and systems herein provide better downlink (DL) data throughput for cell-edge stations (CE STAs). The systems enable protection from a third-party collision during a wideband DL data transmission to the cell edge STA, when the wideband control frame, such as clear-to-send (CTS) or acknowledge (ACK), transmission from a cell edge STA cannot reach the AP. This process can be achieved by designing a new wideband control frame comprising: a legacy preamble sent over the primary 20 MHz channel that can be decoded by the legacy STAs, a new preamble sent over the primary 20 MHz channel that can be used to identify the new wideband control frame (this new preamble has the total signal bandwidth information for the rest of the packet following the new preamble); and duplicate legacy control packets set over the total bandwidth indicated in the new preamble (the legacy control packets can be decoded by the legacy 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: A wireless device, system and method. The device includes a processing circuitry is configured to decode duplicate Request to Send (RTS) frames from a first access point (AP) that is part of an Extended Service Set (ESS) including a second AP, the first AP and the second AP buffering data for the device. The processing circuitry is further to cause transmission of duplicate multi-AP channel bonding (MACB) Trigger frames to the first AP and to the second AP in response to the duplicate RTS frames. Each of the duplicate RTS frames and duplicate Trigger frames have a legacy preamble portion over a first bandwidth of a corresponding wireless channel, and a MACB portion over a second narrower bandwidth of the corresponding wireless channel. The processing circuitry is further to decode a first data frame portion from the first AP and a second data frame portion from the second AP.

Abstract: Provided herein are apparatuses and methods for multiplexed transmission and reception of Relay node. An apparatus includes interface circuitry; and processor circuitry coupled with the interface circuitry, wherein the processor circuitry is to: decode a first-hop message received from a first node via the interface circuitry to obtain a message body; generate, in response to the first-hop message, a first-hop response message for transmission to the first node; generate a second-hop message including the message body for transmission to a second node; and multiplex the first-hop response message with the second-hop message in a same frame for transmission of the first-hop response message and the second-hop message simultaneously. Other embodiments are described and claimed.

Abstract: For example, a wireless communication Station (STA) may be configured to generate a preamble of a Physical Layer (PHY) Protocol Data Unit (PPDU) according to a PPDU frame format. For example the STA may be configured to generate a data payload of the PPDU according to the PPDU frame format. For example, the data payload may include a plurality of data payload portions. For example, the PPDU may include a predefined Training Field (TF) between a first data payload portion and a second data payload portion of the plurality of data payload portions. For example, the STA may be configured to transmit the PPDU.

Abstract: A non-Access Point Extremely High Throughput Station (non-AP EHT STA) initiates a Quality-of-Service (QoS) setup by sending a Stream Classification Service (SCS) Request frame to an associated access point (AP). The SCS request frame may be encoded to have a request type field set to “Add” and may contain an SCS Descriptor element having a traffic description field, a traffic classification field, and a Multi-Link Operation (MLO) field. The non-AP EHT STA may decode an SCS Response frame from the AP that indicate whether the QoS setup has been added. The non-AP EHT STA may then exchange a QoS traffic flow with the associated AP in accordance with the QoS setup when the QoS setup has been added. When the QoS traffic flow ends, the non-AP EHT STA may encode a second SCS Request frame for transmission to the AP with the request type field set to “Remove” to delete the QoS setup.

Abstract: This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

Abstract: The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.
