Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: 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).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for communicating channel selection constraints in a network having multiple access points (APs). In one aspect, a root AP may assist with channel selection (assignment) for the multiple APs. A first AP can provide channel operating constraints to the root AP to indicate one or more operating constraints for a particular channel that may be used by the first AP. The operating constraints may be based, at least in part, on a hardware characteristic of the first AP. For example, an operating constraint may indicate a minimum channel separation or a maximum transmit power to consider when the particular channel is used concurrently with another channel. In another aspect, the first AP can communicate a channel selection error and error code when a particular channel cannot be used due to an operating constraint.

Abstract: Method, systems, and apparatuses are described for wireless communications. More particularly, a wireless station may connect to a wireless network using a first radio frequency (RF) band and detect a signal strength of the first RF band is greater than a roaming threshold. The wireless station may perform a plurality of scans for support by the wireless network of a second RF band in response to the detected signal strength. Each scan may occur when the signal strength of the first RF band is greater than the roaming threshold. The wireless station may selectively connect to the wireless network using the second RF band based at least in part on the scanning and a throughput supported by the wireless network over the second RF band. The first RF band may be a 2.4 GHz band and the second RF band may be a 5 GHz band.

Abstract: This disclosure provides methods, devices and systems for selecting a first group of wireless communication devices to receive a first multi-user (MU) protocol data unit (PDU). A threshold value for identifying collisions of PDUs is determined based on the number of devices in the first group of devices. A second group of wireless communication devices is selected to receive a second MU PDU. Responsive to determining that an acknowledgment (ACK) acknowledging the second MU PDU has not been received from a device of the second group of devices within a threshold duration of time, a number of ACKs, including the ACK, that have not been received from the respective device is determined. An action is then performed based on the determined number of ACKs and the threshold value. In some implementations, the action includes reducing a data rate or initiating a backoff operation.

Abstract: Various aspects of the disclosure provide for Target Wake Time (TWT) slot scheduling in a communication network. The various aspects includes determining a number of stations in the basic service set (BSS) of an access point (AP) exceeding a minimum number of stations, determining whether to establish TWT slot scheduling for at least one or more of the stations based on one or more operational condition of the communication network, and establishing a TWT slot scheduling of the one or more of the stations if the one or more operational condition of the communication network, individually or collectively, satisfy a threshold.

Abstract: This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.

Abstract: Methods, apparatus, and computer-readable media for wireless communication may involve techniques for throughput estimation. An expected air time parameter may be used as a parameter for estimating throughput. The expected air time parameter may be indicative of an estimated air time fraction obtainable for communications using an access point (AP), for example, between a wireless station (STA) and the AP. Either the expected air time parameter or an estimated air time fraction determined (e.g., calculated) from the expected air time parameter may be transmitted from the AP to the STA (or other communication device) to allow the STA (or other communication device) to determine an estimated throughput for communications using the AP.
