Abstract: This disclosure describes systems, methods, and devices related to enhanced multiple access point (AP) coordination. A device may determine a first access point (AP) is an associated AP of a station device (STA). The device may identify a null data packet announce (NDPA) frame received from the first AP. The device may determine a propagation delay between the first AP and the device based on the NDPA frame. The device may identify a multi-AP trigger frame received from the first AP at a first time. The device may cause a data packet to be sent to the STA at a second time, wherein the second time is based on the propagation delay.

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: Embodiments of low-power wake-up packet generation are generally described herein. A wireless device modulates an LP-WUR (low-power wake-up radio) bit sequence with an LP-WUR pulse to obtain a plurality of modulated LP-WUR signals, each modulated LP-WUR signal having a 1× symbol duration. The wireless device multiplexes, in a time domain, an OFDMA (orthogonal frequency division multiple access) signal with a 4× symbol duration with four modulated LP-WUR signals, to generate a multiplexed signal. The wireless device encodes for transmission of the multiplexed signal to a peer device to wake up a WLAN (wireless local area network) radio of the peer device and to another device with an OFDMA signal.

Abstract: A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

Abstract: For example, a wireless communication station (STA) may be configured to generate a plurality of encoded-modulated data streams based on a data field of a PPDU to be transmitted over a channel BW. For example, the plurality of encoded-modulated data streams may be configured based on a plurality of channel BW segments in the channel BW. For example, the plurality of encoded-modulated data streams may include a first encoded-modulated data stream according to a first Modulation and Coding Scheme (MCS) corresponding to a first channel BW segment, and a second encoded-modulated data stream according to a second MCS, e.g., different from the first MCS, corresponding to a second channel BW segment. For example the STA may be configured to transmit a plurality of transmissions based on the plurality of encoded-modulated data streams over the plurality of channel BW segments.

Abstract: An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.
