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: This disclosure describes systems, methods, and devices related to peer-to-peer (P2P) Wi-Fi sensing. A device may generate a request to perform P2P Wi-Fi sensing operations with a second non-AP STA; send the request to an AP to which the non-AP STA is associated; identify a response received from the AP, the response indicating that the non-AP STA is a sensing receiver for the P2P Wi-Fi sensing operations; identify a trigger frame received from the AP, the trigger frame associated with the P2P Wi-Fi sensing operations; identify a sensing physical layer (PHY) protocol data unit (PPDU) received from the second non-AP STA, the sensing PPDU associated with the P2P Wi-Fi sensing operations and including an indication that the second non-AP STA sent the sensing PPDU; and determine channel state information based on the sensing PPDU, the channel state information indicative of motion of people or objects.

Abstract: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

Abstract: A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

Abstract: A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of communicating a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission. For example, a first wireless communication station may be configured to transmit a Request to Send (RTS) to a second wireless communication station via a plurality of SU MIMO Transmit (Tx) sectors of the first wireless communication station, the RTS to establish a Transmit Opportunity (TXOP) to transmit an SU-. MIMO transmission to the second wireless communication station, a control trailer of the RTS including an indication of an intent to transmit the SU-MIMO transmission to the second wireless communication station; and to transmit the SU-MIMO transmission to the second wireless communication station, upon receipt of a Clear to Send (CTS) from the second wireless communication station indicating that the second wireless communication station is ready to receive the STT_M1 N40 transmission.
