Abstract: For example, an Access Point (AP) may be configured to transmit a frame including a prioritized-access enabled/disabled field to indicate whether a prioritized-access contention mechanism is to be enabled or disabled over a wireless medium. For example, the prioritized-access contention mechanism may be configured to allow a prioritized station (STA) to transmit a reservation signal over the wireless medium at a reservation signal transmission time, and to contend the wireless medium according to a high-priority contention policy to obtain a Transmit Opportunity (TxOP) after transmission of the reservation signal. For example, the reservation signal transmission time may be based on an end of a predefined time duration from a start of a contention period. For example, the reservation signal may be configured to indicate a busy Clear Channel Assessment (CCA) to a receiving STA.

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 apparatus may be configured to perform a time-sensitive communication via a Multi User (MU) Multiple-Input-Multiple-Output (MIMO) (MU-MIMO) transmission. For example, an Access Point (AP) may be configured to transmit MU-MIMO schedule information to schedule an MU-MIMO transmission including a plurality of spatial streams, the plurality of spatial streams including a first spatial stream allocated to a scheduled data transmission of a scheduled wireless communication station (STA), and a second spatial stream allocated as a reserved spatial stream, which is reserved for an unscheduled time-sensitive communication with a time-sensitive STA; and to communicate the scheduled data transmission with the scheduled STA over the first spatial stream.

Abstract: The application relates to a method and apparatus used in wireless local area networks (WLANs), the method including: generating a frame comprising information on capability of a non-access point (non-AP) multi-link device (MLD) to simultaneously transmit and receive Physical Layer (PHY) Protocol Data Units (PPDUs); and transmitting the frame to an AP MLD.

Abstract: For example, an Access Point (AP) may be configured to determine that a high-priority contention period is to be initiated during a particular contention period. For example, the AP may be configured to determine that the high-priority contention period is to be initiated during the particular contention period based on a reservation signal received from a station (STA) over a wireless medium during the particular contention period. For example, the AP may be configured to allow the AP to contend the wireless medium during the high-priority contention period according to a high-priority contention policy, for example, to obtain a Transmit Opportunity (TxOP) for transmission of downlink (DL) data to one or more STAs.

Abstract: For example, a wireless communication Station (STA) may be configured to generate a preamble of a Physical Layer (PHY) Protocol Data Unit (PPDU) according to a PPDU frame format. For example the STA may be configured to generate a data payload of the PPDU according to the PPDU frame format. For example, the data payload may include a plurality of data payload portions. For example, the PPDU may include a predefined Training Field (TF) between a first data payload portion and a second data payload portion of the plurality of data payload portions. For example, the STA may be configured to transmit the PPDU.

Abstract: For example, a wireless communication station (STA) may be configured to set a channel bandwidth (BW) field to indicate a channel BW. For example, the STA may be configured to set airtime information in an airtime field. For example, the airtime information may be configured to indicate a required time duration for the STA to communicate one or more frame exchanges of a Quality of Service (QoS) flow over the channel BW. For example, the STA may be configured to transmit a frame to an Access Point (AP). For example, the frame may be configured to include the channel BW field and the airtime field.

Abstract: Embodiments of an access point (AP) configured for extremely high throughput (EHT) operation may be configured to operate as a triggering AP for a trigger-based (TB) peer-to-peer (P2P) communication between a triggered direct (TD) station (STA) and a TD peer STA. The AP may encode a Direct Link Announcement (DiL-A) frame to schedule the TD STA for a direct link transmission to the TD peer STA. The DiL-A frame may be encoded to include a Duration/ID field. The AP may set the Duration/ID field of the DiL-A frame to a remaining duration of a transmission opportunity (TXOP) when the TD peer STA is an EHT STA that supports TB P2P operation (e.g., to allow the TD peer STA to ignore the NAV set by the DiL-A frame). The AP may set the Duration/ID field of the DiL-A frame to a response time for the TD STA to respond to the DiL-A frame when the TD Peer STA is a legacy STA (e.g., to allow the TD peer STA to set its NAV based on the response time).

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable for multi-band operation in a plurality of frequency bands, each frequency band comprising one or more channels. The AP may select a subset of the frequency bands for which the AP is to request per-band channel availability information from the STA. The AP may transmit a Trigger Frame (TF) for a multi-band bandwidth query report polling (MB-BQRP) to request the per-band channel availability information. The AP may receive an uplink frame that includes a multi-band bandwidth query report (MB-BQR) that indicates the per-band channel availability information. The AP may determine, based on the MB-BQR, for an uplink transmission by the STA: one or more frequency bands of the subset of frequency bands, and one or more corresponding channels.

Abstract: For example, a wireless communication station (STA) may be configured to determine whether a stream of frames is suitable for out-of-order delivery from a first Medium Access Control layer (MAC-layer) process to a second MAC-layer process, the second MAC-layer process is above the first MAC-layer process; and, based on a determination that the stream of frames is suitable for out-of-order delivery, to deliver to the second MAC-layer process one or more frames of the stream of frames according to an out-of-order delivery scheme.
