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: An access point (AP) multi-link device (MLD) (AP MLD) comprises a plurality of affiliated access points (APs) including a first affiliated AP (AP1) and a second affiliated AP (AP2). When the first affiliated AP (AP1) is configured to operate as a reporting AP, the reporting AP may encode MLD information in a management frame for transmission to one or more STAs of a station MLD (STA MLD). The MLD information may include a basic service set (BSS) identifier (ID) (BSSID) of the AP1 and may include a BSSID index of at least the AP2 when the AP2 is in a multiple BSSID (MBSSID) set that does not include the BSSID of the AP1. The MLD information may further include at least one of a delivery traffic indication map (DTIM) period of the AP2. The AP1 may decode a frame from a non-AP STA of the STA MLD that includes a BSSID of the MBSSID set for association or reassociation.

Abstract: An access point (AP) station (STA) (AP STA) that is part of an AP multi-link device (MLD) may be configured as a reporting AP may encode a BSS Transition Management (BTM) request frame for transmission to one or more associated non-AP stations (STAs). The BTM request frame may include a neighbor report element encoded to include information about one or more neighbor APs. The neighbor report element may indicate whether the one or more neighbor APs identified in the neighbor report element are part of an AP MLD and, when a neighbor AP is indicated to be part of an AP MLD whether the reporting AP is part of the indicated AP MLD. The AP STA may decode a reassociation frame from one of the non-AP STAs for transition from one of the AP STAs of the AP MLD to one of the neighbor APs.

Abstract: This disclosure describes systems, methods, and devices related to high throughput (HT) control information. A device may determine a frame comprising HT control information. The device may determine to extend a size of the HT control information. The device may cause to generate a management or data frame for sending to a first station device of one or more station devices, the management or data frame comprising extended high throughput (HT) control information, define a new control identification (ID) associated with the extended HT control information, and cause to send the management or data frame to the first station device.

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: A wireless communication device includes a memory, and a processing circuitry coupled to the memory. The processing circuitry is to process a wake-up radio (WUR) frame transmitted by an Access Point (AP), the WUR frame comprising a medium access control (MAC) header and a frame body, the MAC header comprising a Frame Control field, an Address field, and a Type Dependent (TD) Control field, wherein the Frame Control field comprises a Type field; determine, based on a value of the Type field, that the WUR frame is a WUR Discovery frame; determine an identifier (ID) of the AP front the WUR Discovery frame; and in response to a determination that the WUR frame is a WUR Discovery frame, cause a Primary Connectivity Radio (PCR) corresponding to the wireless communication device to communicate with the AP based on the WUR Discovery frame.

Abstract: An access point station (AP) generates a trigger frame (TF) for transmission to two or more non-AP stations (STAs) or groups of STAs. The trigger frame may allocate resource units (RUs) for a trigger-based (TB) transmission to the two or more STAs. The AP may encode the trigger frame to include a Common Info field followed by one or more Special User Info fields. The Common Info field and the one or more Special User Info fields and may be encoded to solicit (i.e., trigger) a trigger-based (TB) Frequency Aggregated Physical layer Protocol Data Unit (PPDU) (FA-PPDU) that includes more than one PPDU of at least two different physical layer (PHY) types from the two or more STAs or groups of STAs. The different PHY types may include high-efficiency (HE), Extremely High Throughput (EHT), Ultra-High Rate (UHR), and UHR+. Accordingly, an AP can trigger a FA-PPDU that includes TB PPDUs of different PHY types.

Abstract: Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
