Abstract: For example, a wireless communication device may be configured to generate a wide bandwidth Long Training Field (LTF) configured for channel sounding over a wide channel bandwidth of at least 320 Megahertz (MHz). For example, the wide bandwidth LTF may include a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols over the wide channel bandwidth. For example, the wireless communication device may be configured to transmit a Null Data Packet (NDP) over the wide channel bandwidth. For example, the NDP may include a non-High-Throughput (non-HT) Short Training Field (L-STF), a non-HIT LTF (L-LTF) after the L-STF, a non-HT Signal (L-SIG) field after the L-LTF, a Repeated L-SIG (RL-SIG) field after the L-SIG field, and the wide bandwidth LTF after the RL-SIG field.

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: Embodiments of a WLAN sensing frame exchange protocol are generally described herein. In some embodiments, a wireless communication device is configured to perform a WLAN sensing protocol within a basic service set (BSS) comprising one or more stations (STAs) (STA1 and STA2) including an access point station (AP STA). The WLAN sensing protocol comprises a discovery phase, a negotiation phase, a measurement phase, and a reporting phase. To perform the WLAN sensing protocol, the wireless communication device is configured to operate as either a sensing initiator or a sensing responder, and to operate as a sensing transmitter and/or a sensing receiver. Some 60 GHz embodiments relate to WLAN sensing in a PBSS or IBSS with DMG STAs.
