Abstract: This disclosure describes systems, methods, and devices related to channel access for multi-link devices (MLDs). A MLD may identify a first backoff count associated with a first enhanced distributed channel access function (EDCAF) for a first communication link used by the MLD; identify a second backoff count associated with a second EDCAF for a second communication link used by the MLD, the first backoff count less than the second backoff count; determine a time period after that the first backoff count reaches zero and during which to refrain from transmitting using the first communication link, the time period based on the second backoff count; determine that the first communication link transitioned from an idle state to a busy state during the time period; and generate a third backoff count associated with the first EDCAF based on the first communication link transitioning to the busy state during the time period.

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: For example, a beacon, e.g., which may be communicated from an Access point (AP) Multi-Link Device (MLD) to a non-AP MLD, may be configured according to a multi-link Traffic Indication Map (TIM) mechanism. For example, the beacon may include a TIM bitmap including a bit set to “1” to indicate buffered traffic for the non-AP MLD. For example, the beacon may include a link bitmap corresponding to the non-AP MLD. For example, the link bitmap corresponding to the non-AP MLD may include a plurality of bits corresponding to a respective plurality of links for the non-AP MLD. For example, a bit in the link bitmap may be set to “1” to indicate a link for retrieving one or more buffered Bufferable Units (BUs) for the non-AP MLD.

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 wireless time sensitive networking. A device may identify, using an 802.3 protocol stack, an 802.3 frame received from a second device using a wired Ethernet connection, and extract, using the 802.3 protocol stack, a redundancy tag from the 802.3 frame, the redundancy tag including a sequence number. The device may generate, using an 802.11 protocol stack, an 802.11 frame with a subnetwork access protocol (SNAP) field, the SNAP field including an organizationally unique identifier (OUI) and the sequence number, the OUI including an indication of an Ethertype protocol. The device may send the 802.11 frame using a wireless connection.

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.
