摘要： An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

摘要： 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.

摘要： 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.

摘要： A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

摘要： An apparatus of a first high-efficiency (HE) access point (AP) or station for spatial reuse is the disclosed. The apparatus includes processing circuitry configured to: decode a first portion of a first packet; and if the first portion indicates the first packet was transmitted by a second HE AP or station and that the first packet is an overlapping basic service set (OBSS) packet, then if a preamble detect energy is below a threshold, cause to be transmitted a second packet simultaneously with a portion of the first packet after the first portion. The processing circuitry may be configured to determine the first portion was transmitted by the second HE AP or station if a field in a physical (PRY) header or a second field in a media access control (MAC) header indicate the first packet was transmitted by the second HE AP or station.
