Abstract: This disclosure describes systems, methods, and devices related to an extreme high throughput (EHT) signaling structure. A device may establish a communication channel with one or more station devices (STAs). The device may generate an extreme high throughput signal field (EHT-SIG) of a header, wherein the EHT-SIG field comprises information associated with resource allocations (RUs). The device may generate a frame comprising the header. The device may assign a first RU to a first station device. The device may assign a second RU to the first station device, wherein the first RU or the second RU is an aggregation of a 26-tome RU and a neighboring RU. The device may cause to send the frame to the first station device.

Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operations. A multi-link device (MLD) may establish a first communication link between a first device of the MLD and a first device of a second MLD, and a second communication link between a second device of the MLD and a second device of the second MLD. The MLD may generate a group-addressed message. The MLD may protect the group-addressed message using a first key or a first integrity key. The MLD may protect the group-addressed message using a second key or a second integrity key. The MLD may send, using the first communication link, the group-addressed message protected using the first key or the first integrity key, and may send, using the second communication link, the group-addressed message protected using the second key or the second integrity key.

Abstract: Multi-link device (MLD) devices and transitions are described. The MAC addresses of the AP MLD and non-AP MLD are used to generate keys for different fast transitions (FT) between a non-AP MLD and an AP MLD. In an FT initial mobility domain operation, the AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S0KH-ID and S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in a single FT 4-way handshake. In a fast MLD transition to an AP MLD in the same ESS, the other AP MLD MAC address is used as the R1KH-ID and the non-AP MLD MAC address is used as the S1KH-ID. The MAC addresses are exchanged in Authentication Request/Response or Association Request/Response messages and the GTK/IGTK/BIGTK are delivered in an FTE.

Abstract: This disclosure describes systems, methods, and devices related to low latency preemption. A device may divide a first PPDU into a plurality of segmented PPDUs. The device may insert a plurality of time gaps between the plurality of segmented PPDUs, wherein the plurality of time gaps enable preemptive opportunities by a low latency transmitter. The device may identify a preemption request from a low latency transmitter of the one or more station devices during a first time gap between a first segmented PPDU and a second segmented PPDU. The device may preempt the second segmented PPDU based on a preemption bit in order to allow the low latency transmitter to transmit its low latency data.

An apparatus is disclosed comprising processing circuitry configured to decode a supported HE-MCS and a NSS set field, the supported HE-MSC and NSS set field received from an high-efficiency (HE) station. The processing circuitry may be further configured to determine a first maximum value of N receive (Rx) SS for a MCS and a bandwidth (BW), where the first maximum value of N Rx SS is equal to a largest number of Rx SS that supports the MCS for the BW as indicated by the supported HE-MCS and NSS set field; and, determine additional maximum values based on an operating mode (OM) notification frame, and a value of an OM control (OMC) field. Signaling for BW in 6 GHz is disclosed.

Abstract: Logic may generate a wake-up radio packet, wherein the wake-up radio packet comprises an on-off keying (OOK) signal, a sequence of a preamble of the wake-up radio packet to indicate a rate of transmission of one or more OOK orthogonal frequency-division multiplexing (OFDM) symbols of a medium access control (MAC) frame of the wake-up radio packet, wherein a duration of transmission of the preamble is 128 microseconds for a low data rate and a duration of transmission of the preamble is 64 microseconds for a low data rate. Logic may communicate the wake-up radio packet to a physical layer device to transmit OFDM symbols of an IEEE 802.11 preamble on a channel followed by OOK OFDM symbols of the wake-up radio packet on a sub-band of the channel. And logic may generate at least a second wake-up radio packet to transmit on a contiguous channel bandwidth with OOK OFDM symbols.
