Extreme high throughput (EHT) time-sensitive networking

An apparatus of an access point (AP), the apparatus comprising:

• processing circuitry;
• and memory,
• wherein the processing circuitry is to configure the AP to control contention with a BSS for protection of time-sensitive traffic,
• wherein to control contention with the BSS, the processing circuitry is configured to:
• set a contention access disabled field within an information element (IE) in a beacon, broadcast or management frame, the contention access disabled field to indicate to STAs of the BSS to disable EDCA contention access and wait for trigger-based access allocations to transmit data
• wherein the contention access disabled field is configurable to indicate that EDCA contention access is disabled for data frame transmission but enabled for management frame transmissions.

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an access point (AP),

• wherein when configured by the processing circuitry to operate as a coordinator AP for performing basic service set (BSS) channel level coordination, the coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs (OBSSs) to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS,
• wherein to perform the BSS channel level coordination, the processing circuitry of the coordinator AP is configured to exchange channel management frames with the coordinated APs, wherein the channel management frames indicate one or more channels to be used for the time-sensitive traffic,
• wherein to further perform the BSS channel level coordination, the processing circuitry of the coordinator AP is configured to coordinate usage of the one or more channels to be used for the time-sensitive traffic to steer traffic and avoid congestion and latency issues that would be caused by mixing the time-sensitive traffic with other traffic on a same channel,
• wherein when configured by the processing circuitry to operate as a coordinator AP for performing transmission level coordination, the coordinator AP is configured to initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among the one or more coordinated APs of the OBSSs,
• wherein to perform the BSS channel level coordination, the processing circuitry of the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP, the M-TF being encoded to include a time-sensitive operation information element (IE), the time-sensitive IE indicating how each STA is to access a channel within the coordinated TXOP.
