Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may buffer uplink communications. However, such approaches may be improved. An access point (AP) may receive, from a station, uplink traffic of a traffic flow for forwarding to a backhaul network via a backhaul link. The AP may monitor a buffer of the AP to determine that a quantity of buffered uplink traffic received from the station exceeds a buffer quota, the buffer quota set for the traffic flow based on a traffic throughput capacity of the backhaul link and a throughput parameter for the traffic flow. The AP may modify, based on the quantity of buffered uplink traffic exceeding the buffer quota, an uplink communication scheme to reduce the quantity of uplink traffic from the station. The AP may communicate with the station based on the modified uplink communication scheme.

Uplink flow control

A first Multi-AP device configured as a Multi-AP Agent transmits, to a second Multi-AP device configured as a Multi-AP Controller over a first communication link, a Device Provisioning Protocol (DPP) Configuration Request Message indicating multi-link operation (MLO) capabilities of the first Multi-AP device. The first Multi-AP device receives, from the second Multi-AP device over the first communication link, a DPP Configuration Response Message indicating MLO association information responsive to the indicated MLO capabilities, and establishes a backhaul path with a third Multi-AP device, configured as a second Multi-AP Agent, on the first communication link and one or more second communication links according to the MLO association information. The MLO capabilities may be indicated in a DPP Configuration Object of the DPP Configuration Request Message, and the MLO association information may be indicated in a multi-link device (MLD) address field of a DPP Configuration Object of the DPP Configuration Response Message.

Multi-link operation (MLO) for easy mesh

This disclosure provides methods, devices and systems for provisioning resources for wireless communications. Some implementations more specifically relate to provisioning such resources based on a mapping of wireless communication devices to a number of time sectors that occur periodically and do not overlap other time sectors. In some aspects, each wireless stations (STAs) in a basic service set (BSS) may be mapped to a respective time sector based on attributes associated with the BSS so that communications between a STA and its associated access point (AP) can only occur within the respective time sector(s) to which the STA is mapped. In some other aspects, each AP in a multi-AP environment may be mapped to a respective time sector based on attributes associated with the multi-AP environment so that communications between an AP and its associated STAs can only occur within the respective time sector(s) to which the AP is mapped.

Network time sectoring

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a packet duration for triggered uplink (UL) transmissions to an access point (AP) from one or more stations (STAs). In one aspect, the AP may estimate an amount of data that a STA has queued for UL transmission and select the packet duration based on the estimated amount of queued UL data. The AP may transmit a trigger frame that solicits UL data from the STA and indicates the selected packet duration. In response, the AP may receive an UL packet from the STA and determine an amount of UL data queued in the STA based on the UL packet. In some implementations, the AP may selectively adjust the packet duration for UL transmissions based on the UL packet, the determined amount of UL data queued in the STA, or both.

Selective adjustment of packet durations

Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.

Managed MU-MIMO enablement for real-world applications

Methods, systems, and devices for wireless communications are described. A first device may receive signaling associated with a traffic class from a second device. The first device may determine that the traffic class is included in a set of known traffic classes based on a set of features associated with the signaling. In response to determining that the traffic class is included in the set of known traffic classes, the first device may use a machine learning model to obtain a prediction of an application associated with the signaling. The prediction may be based on the set of features. The machine learning model may be trained at the first device or the second device. The first device may receive information associated with the machine learning model from the second device.

Traffic identification using machine learning

This disclosure provides systems, methods and apparatus for synchronous channel access control of a wireless system. In some aspects, a device may use a TWT session to communicate with a second device during one or more TWT service periods. Uplink and downlink communications may be coordinated to both be in a TWT service period to allow a device to enter a low power mode outside of the TWT service period. The TWT session, including the service periods, may be configured and managed by the device or the second device to ensure the communications associated with an XR experience between the devices (such as pose data frames or tracking frames provided as uplink data and video data frames provided as downlink data) meet latency requirements or other requirements for the XR experience. Use of TWT service periods allows other devices to use the wireless medium outside of the TWT service periods.

Synchronous channel access control of a wireless system

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In some implementations, a wireless communication device obtains one or more indications that a wireless station (STA) will enter a power-save mode, selects, for each respective STA of a plurality of STAs, a duration associated with the respective STA entering the power-save mode, and adjusts one or more parameters of a multi-user channel access mechanism for transmitting uplink data associated with the selected duration. In some other implementations, a wireless communication device outputs one or more indications that the device will enter a power-save mode, outputs or obtains data at each of a plurality of first instances, enters the power-save mode at each of a plurality of second instances, and obtains a beacon indicating one or more parameters to be used for a multi-user channel access mechanism for transmitting uplink data.

Dynamic parameters for multi-user channel access

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Wireless network configuration for low-latency applications

This disclosure provides methods, devices and systems for transmitting, to one or more local area network clients of the device, a multicast message indicating an available network slice, receiving, from a first local area network client of the one or more local area network clients based on the multicast message, a request to access the available network slice, establishing, at the device based on receiving the request, a connection associated with the available network slice, and transmitting, to the first local area network client based on establishing the connection, a confirmation to access the available network slice.

Local area network client participation in a network slice

This disclosure provides systems, methods and apparatus for asynchronous channel access control of a wireless system. In some aspects, a device may adjust the priority of one or more PPDUs and may perform other operations to ensure control of a wireless medium at certain times while still allowing for other devices to communicate on the wireless medium. For example, the device may adjust a backoff counter or one or more EDCA parameters to ensure obtaining control of the wireless medium to transmit a first PPDU of an application file. For one or more subsequent PPDUs of the application file, the device may again adjust a backoff counter or one or more EDCA parameters to allow other devices to obtain control of the wireless medium in certain scenarios (such as a second device to provide information back to the device or to otherwise transmit using the shared wireless medium).

Asynchronous channel access control of a wireless system

This disclosure provides methods, devices and systems for controlling basic service set (BSS) configuration of an access point (AP) in a multi-AP network. The multi-AP network may include a first AP that manages a first basic service set (BSS) and a second AP that manages a second BSS. The first BSS and the second BSS may share one or more wireless channels or may have overlapping coverage areas. A multi-AP controller may determine a BSS configuration policy (such as a maximum transmission opportunity (TXOP) duration) for the second BSS based on a type of traffic in the first BSS. This disclosure includes techniques for sharing traffic characteristics, determining the BSS configuration policy, communicating the BSS configuration policy, and controlling the BSS configuration policies for multiple BSSs so that one of the BSSs can provide a quality of service (QoS) for one or more stations (STAs).

Basic service set (BSS) configuration in a multiple access point (multi-AP) network

Certain aspects relate to methods and apparatus for traffic separation in a multi AP (MAP) network. In some cases, a MAP Controller may configure sets of SSIDs to a single VLAN ID in a Traffic Separation Policy and distribute the Traffic Separation Policy information to the MAP Agents.
