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: An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

Abstract: Embodiments of a multi-link access point (AP) device, station (STA) and method of communication are generally described herein. The multi-link AP device may comprise multiple APs. The multi-link AP device may encode a frame for transmission by one of the APs of the multi-link AP device. The multi-link AP device may encode the frame to include signaling to enable multi-link discovery of the APs of the multi-link AP device. The multi-link AP device may encode the signaling to include: a reduced neighbor report (RNR) element that identifies the APs of the multi-link AP device, and a multiple AP element. The multiple AP element may be configurable to include: common information for the APs of the multi-link AP device, and per-AP sub-elements that include per-AP information related to the APs of the multi-link AP device.

Abstract: A method of wireless communication comprising decoding in a physical layer circuitry a received wireless signal; outputting a corresponding wireless signal data as one or more data packets, the wireless signal data representing the received wireless signal; determining one or more packet header parameters of the one or more data packets; and if any of the one or more packet header parameters equal any of one or more predetermined values, instruct a medium access control layer circuitry to switch from an inactive mode to an active mode.

Abstract: The application relates to a method and apparatus used in Wireless Local Area Networks (WLANs). The apparatus includes: a Radio Frequency (RF) interface; and processor circuitry coupled with the RF interface and configured to: determine Buffered Unit (BU) information, which indicates presence or absence of BUs for a set of non-Access Point (AP) Multi-link Devices (MLDs) on an AP MLD; encapsulate the BU information for the set of non-AP MLDs in a Multilink (ML) Traffic Indication Map (TIM) information element; and provide the ML TIM information element to the RF interface for broadcasting, wherein the ML TIM information element comprises a series of TIM segments and each TIM segment contains the BU information, which indicates the presence or absence of BUs for a subset of non-AP MLDs on a corresponding AP within the AP MLD.

Abstract: Multi-link device (MLD) security association (SA) query and query response procedures are described. Any of the links between an access point (AP) MLD and a non-AP MLD may be used to initiate association, reassociation, or disassociation procedures using the SA query requests and responses. The SA query request or response from one of the stations (STAs) associated with the MLD is sent to a corresponding linked one of the STAs associated with the other MLD. The SA request or response is addressed to the other MLD rather than the STA of the other MLD. Retry timeouts and maximum timeouts for resending SA query requests are set by the AP MLD and the same across each of the links.

Abstract: This disclosure describes systems, methods, and devices related to enhanced frame exchange. A device may generate a first subset of a plurality of fields, wherein the first subset is mandatory in a probe request frame. The device may generate a second subset of the plurality of fields, wherein the second subset is optional in the probe request frame regardless of capability information of the device. The device may generate the probe request frame comprising the first subset and the second subset. The device may cause to send the probe request frame to an access point (AP) device.

Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.
