Abstract: 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.

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: 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.

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).

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.

Abstract: 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.

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 implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS).

The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.

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: 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: 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.

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.
