Abstract: For example, an apparatus may include logic and circuitry configured to cause a non Access Point (AP) (non-AP) station (STA) to set one or more Segment-Association-Information (SAI) queue-size subfields in a control field. For example, the one or more SAI queue-size subfields may indicate queue sizes of one or more SAI queues at the non-AP STA. For example, an SAI queue of the one or more SAI queues may queue packet segments corresponding to a same application layer packet. For example, the non-AP STA may be configured to transmit a frame to an AP, wherein a Media Access Control (MAC) header of the frame includes the control field.

Abstract: This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

Abstract: Embodiments of a beacon interval with boundary time points (BTPs) to improve latency for time sensitive traffic (TST) in Extremely High Throughout (EHT) WLANS are disclosed herein. In some embodiments, a non-access point (AP) station (STA) is configured to decode a beacon frame received from an AP STA. The beacon frame may indicate one or more BTPs within a beacon interval (BI). The non-AP STA may obtain a transmission opportunity (TXOP) for a transmission to the AP STA. The TXOP may be bounded by the one or more BTPs. The non-AP STA may encode a PPDU for transmission to the AP STA during the TXOP.

Abstract: This disclosure describes systems, methods, and devices related to aligned channel access. A device may perform a first backoff countdown on a first link associated with a first station device (STA) of the device, wherein the device is a multi-link device (MLD). The device may detect a second backoff countdown associated with a second STA of the MLD after the first backoff countdown reaches zero. The device may determine to hold the first backoff countdown at zero based on the value of the second backoff countdown. The device may transmit in synchronization on the first link and on the second link from the first STA and the second STA respectively based on holding the first backoff countdown at zero.

Abstract: This disclosure describes systems, methods, and devices related to enhanced traffic model. A device may maintain, at an upper layer, a self-ordering queue associated with one or more time sensitive packets associated with times sensitive traffic streams. The device may transmit the one or more time sensitive packets from the self-ordering queue to a TSN queue at a lower layer. The device may control one or more enhanced distributed channel access (EDCA) queues by using a control function. The device may transmit the one or more time sensitive packets to a first station device.

Abstract: For example, a first non Access Point (AP) (non-AP) wireless communication station (STA) and/or an AP may be configured to communicate End to End (E2E) Quality of Service (QoS) information corresponding to an E2E traffic flow. For example, the non-AP STA may be configured to set E2E QoS information in a Stream Classification Service (SCS) descriptor element. For example, the E2E QoS information may be configured to indicate an E2E QoS requirement for an E2E traffic flow to be communicated between the first non-AP STA and a second non-AP STA. For example, the non-AP STA may be configured to transmit an SCS request to the AP. For example, the SCS request may include the SCS descriptor element.

Abstract: For example, an Access Point (AP) may be configured to set an Association Identifier (AID) field to a predefined AID value. For example, the predefined AID value may be configured to indicate that a non-AP station (STA) having latency-sensitive traffic is to be allowed to transmit a non-Trigger-Based (non-TB) Physical layer (PHY) Protocol Data Unit (PPDU) including the latency-sensitive traffic according to a channel contention mechanism during a contention-based time period. For example, the AP may be configured to transmit a trigger frame to allocate the contention-based time period. For example, the trigger frame may include the AID field.

Abstract: An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. The S-TXOP slots may be configured for communication of synchronous data. For communication of small time-critical (TC) packets within the S-TXOP with one or more of the STAs, the AP may configure the S-TXOP for asynchronous ultra-low latency (ULL) transmissions by providing a low-latency channel access opportunity within the S-TXOP.
