This disclosure provides systems and methods for use of automated frequency coordination (AFC) to manage transmission power and frequencies. In some implementations, a device transmits, to a network entity, an AFC request. The device receives, from the network entity, an AFC response, the AFC response including an AFC power level indication of one or more nearest neighboring entities. The device sets a transmit power of the device based at least in part on the AFC power level indication of at least one of the one or more nearest neighboring entities, and the device transmits at the transmit power. In some instances, the device transmits a first number of AFC requests during a first instance of travelling along a path and transmits a second number of AFC requests less than the first number of AFC requests during one or more successive instances after the first instance of travelling along the path.

Automated frequency coordination for high speed mobility

An access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field, one or more secondary change sequence fields, and a critical update flag subfield. The first change sequence field carries a value of the most-recent critical update for the first AP. The one or more secondary change sequence fields carry values of the most-recent critical updates for the one or more respective secondary APs. The critical update flag subfield carries an indication of a change in value of at least one of the secondary change sequence fields. The first AP transmits the frame over the first communication link of the AP MLD.

Early critical update indications for multi-link devices

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 systems, devices, apparatus and methods, including computer programs encoded on storage media, for high efficiency (HE) beacons. HE supported access points (APs) and stations (STAs) may operate on resource deployments used for Wi-Fi technology and without support for legacy devices, also referred to as a greenfield deployment. An AP may identify updated capability information and transmit a HE physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a beacon frame. A STA may receive, from the AP, the HE or EHT PPDU and identify an indication of change to a content or format of the beacon frame relative to a reference beacon frame. Based on the identified indication, the STA may then determine an updated content or format for the beacon frame and process the beacon frame or skip processing for one or more portions of the beacon frame.

High efficiency signaling

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.

Conditional inheritance in management frame for multi-link aggregation

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 station (STA) may receive a first signal including an indication of a set of frequency channels for a set of target wake time (TWT) sessions that recur according to a service interval. In some examples, the first signal may indicate a respective frequency channel of the set of frequency channels for each TWT session of the set of target wake time sessions. Each TWT session of the set of TWT sessions may have an associated service period that the STA may be in an awake state. The STA may switch, for the first TWT session, from the first frequency channel to the second frequency channel. In some examples, based on the switching, the STA may communicate a signal during a service period associated with the first TWT session over the second frequency channel.

Managing hopping target wake times for wireless networks

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, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

Reception of management frames for multiple basic services sets (BSSs)

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 methods, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), an indication of a puncturing event. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the puncturing event. In certain aspects, the disclosure provides methods for transmitting and receiving, between the AP and one or more STAs, an indication of an operating band switch. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the operating band switch.

Channel puncturing

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 adjusting a time period to delay entering a power save mode (leak guard) for wireless communications. In one aspect, a wireless communication device may adjust a time period to delay entering a power save mode. The time period is associated with the wireless communication device remaining awake to prevent an access point from transmitting to the wireless communication device while the wireless communication device is in the power save mode. The wireless communication device also may provide, to the AP, an indication that the wireless communication device is entering a power save mode, and the wireless communication device may enter the power save mode. Entering the power save mode is at least the adjusted time period after providing the indication to the AP.
