An AP obtains service-level agreement (SLA) parameters indicating at least a delay bound for each of a plurality of traffic flows. The AP receives first packets of a first traffic flow, and delays their transmission for a delay period based on the data carried in the first packets being less than a first threshold. During the delay period, the AP receives second packets of the first traffic flow while also receiving packets of a second traffic flow, groups the second traffic flow with the first traffic flow for an MU-MIMO transmission based on the data carried in the first and second packets of the first traffic flow being greater than the first threshold and the data carried in the packets of the second traffic flow being greater than a second threshold, and transmits the first and second packets traffic flows as an MU-MIMO communication.

Dynamic MU-MIMO staging for real-world applications

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

Certain aspects of the present disclosure provide an architecture and method for multi-link operation (MLO) at an access point (AP). The method generally includes obtaining a packet from at least one buffer and selecting a processing path, from first and second processing paths, for a packet to be routed from the at least one buffer to at least one of a plurality of radio components for wireless transmission to at least one peer via one or more links, wherein: the first processing path is configured to bind the packet to one of the one or more links based on at least one code-implemented rule, and the second processing path is configured to bind the packet to one of the one or more links based on instantaneous channel sensing.

Flexible multi-link operation architecture

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an access point may start a target wake time (TWT) service period (SP). The access point may receive an end of SP (EOSP) indication from a station. The access point may stop the TWT SP before a scheduled end of the TWT SP based on receiving the EOSP indication. Numerous other aspects are described.

End of service period indication

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

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

Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Flexible negotiation of parameters in setup exchanges for wireless communication sessions

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, to mitigate a denial of service attack to a power line communication (PLC) network. A first node of the PLC network may activate a countermeasure that enables the PLC network (including the first node and a second node) to continue to communicate when one or more transmissions associated with a denial of service attack are injected onto the communication medium. This disclosure includes several techniques to detect a denial of service attack and several countermeasures that may be implemented. For example, a countermeasure may include the use of a custom preamble or a custom priority resolution symbol that is specific to the PLC network. The first node and the second node may disregard transmissions that do not conform to the custom preamble or custom priority resolution symbol.

Power line communication (PLC) denial of service attack

This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media that support station performance enhancement with multi-link operations. An example method may include determining at least one network metric related to at least one link between a station (STA) and access points (APs) and determining at least one connection parameter related to at least one application operating on the STA. The method may include selecting a mode of multi-link operations based at least in part on the network metric and the connection parameter, wherein the mode of multi-link operations comprises one or more of: a multi-link mode in which the STA operates over a first link and a second link at a same time or a single-link mode in which the STA operates over one of the first or second links and communicating with the one or more APs according to the selected mode.

Station performance enhancement with multi-link operations (MLO)

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

The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
