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: This disclosure describes systems, methods, and devices related to scrambler initialization for multi-user (MU) clear to send (CTS) transmission. A first device may identify a MU request to send (RTS) frame received from a second device. The first device may determine an initial state of a scrambler based on the first 7 bits of a service field of the MU-RTS frame. The first device may cause first data to be scrambled, using the initial state of the scrambler, resulting in second data. The first device may cause to send a MU-CTS frame that comprises the second data to the second device.

Abstract: This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection. A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

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.
