Abstract: This disclosure describes systems, methods, and devices related to an enhanced retry count for an uplink (UL) multi-user (MU) transmission. A device may identify a trigger frame received from a first device on a wireless communication channel. The device may determine a quality of service counter associated with an access category. The device may cause to send a frame to the first device based at least in part on the trigger frame. The device may determine an error condition associated with the frame. The device may refrain from incrementing the quality of service counter based on the error condition.

Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

Abstract: Embodiments of a multi-link device (MLD) are generally described herein. The MLD may be configured for multi-link communication on a plurality of links. The MLD may be configured with a plurality of stations (STAs). Each STA may be a logical entity that includes a singly addressable instance of a medium access control (MAC) layer and a physical (PHY) layer of a link of the plurality of links. The MLD may configure traffic identifier (TID) assignment for the MLD for multi-link communication with another MLD. The multi-link communication may be configurable to support one or more data streams, wherein each of the data streams corresponds to a TID. The MLD may determine an assignment of the TIDs to the STAs of the MLD.

Abstract: This disclosure describes systems, methods, and devices related to security for multi-link operation. A device may determine a multi-link communication with a first multi-link device comprising two or more links associated with two or more station devices (STAs) included in the first multi-link device. The device may determine a first medium access control (MAC) address associated with a first link of the two or more links. The device may determine a second MAC address associated with a second link of the two or more links. The device may generate one or more pairwise security keys to be used in the multi-link communication on the two or more links. The device may cause to send a frame to the first multi-link device using at least one combination of the one or more pairwise security keys.

Abstract: Some demonstrative embodiments may include apparatus, system and method of scheduling Time Sensitive Networking (TSN) wireless communications. For example, an apparatus may include logic and circuitry configured to cause a wireless communication Access Point (AP) to allocate at least one Time Sensitive Networking (TSN) enabled (TSN-enabled) Target Wakeup Time (TWT) Service Period (SP) based on one or more timing requirements of a TSN schedule of at least one TSN stream for at least one wireless communication station (STA); to transmit a TWT scheduling message to schedule the TSN-enabled TWT SP, the TWT scheduling message including an indication that the TSN-enabled TWT SP is restricted to only TSN communications; and, during the TSN-enabled TWT SP, to communicate one or more frames of the at least one TSN stream with the at least one STA.

Abstract: Methods, computer readable media, and apparatus for determining a receive (Rx) number of spatial streams (NSS) for different bandwidths (BWs) and modulation and control schemes (MCSs) are disclosed. 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: Embodiments of transitioning between BSSs using on-channel tunneling (OCT) are generally described herein. OCT procedures are used for scanning and association with a co-located or non-co-located peer AP. The OCT procedures include communicating a Probe/Re-authentication/Re-association Request frame from a STA using an OCT Request frame to the peer AP and receiving a Probe/Re-authentication/Re-association Response frame from the peer AP using another OCT Request frame. The communications between the STA and the AP are either in the same frequency band or a different frequency band as the OCT communications between the AP and the peer AP.
