An apparatus is disclosed comprising processing circuitry configure to: encode a fine timing measurement (FTM) initiate (FTI) frame, the FTI frame comprising M0 message uplink resource allocations for a plurality of responders to transmit M0 messages to the HE STA. The processing circuitry further configured to configure the HE STA to transmit the FTI frame to the plurality of responders, and decode M0 messages from the plurality of responders in accordance with the M0 message uplink resource allocations, where the M0 messages are to be received at the HE STA at times T2 in accordance with multi-user multiple-input multiple-output (MU-MIMO). The processing circuitry further configured to acknowledge the M0 messages to be transmitted at a time T3, and decode M1 messages comprising a corresponding time T1 and time T4.

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： This disclosure describes systems, methods, and devices related to enhanced traffic model. A device may maintain, at an upper layer, a self-ordering queue associated with one or more time sensitive packets associated with times sensitive traffic streams. The device may transmit the one or more time sensitive packets from the self-ordering queue to a TSN queue at a lower layer. The device may control one or more enhanced distributed channel access (EDCA) queues by using a control function. The device may transmit the one or more time sensitive packets to a first station device.

摘要： This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

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.
