    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: For example, a wireless communication station (STA) may be configured to set flow-group Quality of Service (QoS) information corresponding to a Medium Access Control (MAC) Service Data Unit (MSDU) in a traffic flow belonging to a flow group including a plurality of traffic flows. For example, the flow-group QoS information corresponding to the MSDU may include a flow identifier (ID) to identify the traffic flow, a flow group ID to identify the flow group, and MSDU set information corresponding to an MSDU set including the MSDU. For example, the STA may be configured to transmit a Physical Layer (PHY) Protocol Data Unit (PPDU) including the MSDU, wherein the PPDU includes the flow-group QoS information corresponding to the MSDU.

    Abstract: This disclosure describes systems, methods, and devices related to multi-link devices (MLDs). A MLD may identify a first security key received from a first access point MLD (A-MLD); identify a second security key received from the first A-MLD; transmit, from a first physical location, a first packet to the first A-MLD, the first packet including the first security key; identify a first subset of N packets, the first subset received from the first A-MLD; transmit, from a second physical location, a second packet to the second A-MLD, the second packet including the second security key; identify a second subset of the N packets, the second subset received from the second A-MLD; determine that a third packet of the N packets was not received; and transmit, to the first A-MLD or the second A-MLD, an indication that the third packet was not received.

    Abstract: For example, an apparatus may be configured to cause an Extremely High Throughput (EHT) wireless communication station (STA) to set a control field including presence signaling information corresponding to a plurality of parameter fields, the presence signaling information configured to indicate, for a parameter field of the plurality of parameter fields, whether the parameter field is to be present or absent in a Quality of Service (QoS) element; and to transmit a frame including the QoS element, the QoS element including the control field, wherein the presence or absence of the plurality of parameter fields in the QoS element is configured according to the presence signaling information in the control field.

    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.
