Abstract: This disclosure describes systems, methods, and devices related to EHT training fields. A device may send a trigger frame having a type of HE null data packet (NDP) feedback, wherein the trigger frame requests feedback from a station device (STA) of one or more station device (STA). The device may receive a frame from the STA, wherein the frame comprises an HE long training field (HE-LTF) portion and an HE short training field (HE-STF), wherein the HE-STF is generated in a frequency domain over a first bandwidth. The device may identify that the HE-LTF comprises energy on a set of tones, wherein the set of tones are selected based on feedback status values associated with a resource unit (RU) tone set index. The device may identify that the HE-STF comprises a second set of tones that are energized based on a sequence that is selected based on the first bandwidth used for the frame

Abstract: This disclosure describes systems, methods, and devices related to channel access for multi-link devices (MLDs). A MLD may identify a first backoff count associated with a first enhanced distributed channel access function (EDCAF) for a first communication link used by the MLD; identify a second backoff count associated with a second EDCAF for a second communication link used by the MLD, the first backoff count less than the second backoff count; determine a time period after that the first backoff count reaches zero and during which to refrain from transmitting using the first communication link, the time period based on the second backoff count; determine that the first communication link transitioned from an idle state to a busy state during the time period; and generate a third backoff count associated with the first EDCAF based on the first communication link transitioning to the busy state during the time period.

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: 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 multi-link power save indication. A device may establish two or more links with a non-access point (AP) multi-link device (MLD). The device may connect a first AP of the AP MLD to a first station device (STA) of the non-AP MLD using a first link. The device may connect a second AP of the AP MLD to a second STA of the non-AP MLD using a second link. The device may use a link bitmap field included in a frame, wherein the link bitmap field comprises a first bit associated with the first STA and a second bit associated with the second STA. The device may communicate with the non-AP MLD based on the link bitmap.

Abstract: Embodiments of a beacon interval with boundary time points (BTPs) to improve latency for time sensitive traffic (TST) in Extremely High Throughout (EHT) WLANS are disclosed herein. In some embodiments, a non-access point (AP) station (STA) is configured to decode a beacon frame received from an AP STA. The beacon frame may indicate one or more BTPs within a beacon interval (BI). The non-AP STA may obtain a transmission opportunity (TXOP) for a transmission to the AP STA. The TXOP may be bounded by the one or more BTPs. The non-AP STA may encode a PPDU for transmission to the AP STA during the TXOP.

Abstract: This disclosure describes systems, methods, and devices related to in-channel and adjacent channel interference avoidance. The device may perform a clear channel assessment (CCA) measurement on a portion of a second operating channel, wherein the portion shares a contiguous edge with a first operating channel that is adjacent to the second operating channel. The device may detect an energy on the portion of the second operating channel based on the CCA measurement. The device may compare the detected energy to an energy detection (ED) threshold. The device may determine to communicate on the second operating channel based on the comparison of the energy to the ED threshold.

Abstract: This disclosure describes systems, methods, and devices related to neighbor awareness networking (NAN) operations in the 6 GHz frequency band. A NAN device may generate a first NAN frame including a first indication of a NAN operation capability, and a second indication of a transmit power of the NAN device. The NAN device may send the first NAN frame and may identify a second NAN frame received from a second NAN device, the second NAN frame including a third indication of the NAN operation capability, and a fourth indication of a transmit power of the second NAN device. The NAN device may determine, based on the transmit power of the NAN device and the transmit power of the second NAN device, an operation parameter for the 6 GHz frequency band. The NAN device may establish, based on the operation parameter, a NAN connection using the 6 GHz frequency band.
