Abstract: This disclosure provides methods, components, devices and systems for announcing opportunistic primary channel switching. Various aspects generally relate to a channel switch announcement (CSA) element that may announce an opportunistic primary (O-Primary) channel switch. Various aspects relate more specifically to an expanded channel switch mode field of a CSA element that may indicate whether a wireless station (STA) is permitted to transmit via the first O-Primary channel during the switch, whether a new operating class field is present in the CSA element, and an index associated with the switched O-Primary channel. In some aspects, the CSA element may be a separate information element, or an element defined within a non-primary channel access (NPCA) wrapper. The AP may transmit the CSA element via a beacon frame, a probe response frame, or a dedicated channel switch announcement frame.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

In some examples, a vendor-specific (VS) IE or another IE. In some examples, the associated TSF field may be a TSF field of the beacon frame or of a recurring time epoch, such as a target beacon transmission time (TBTT) of the beacon frame.

Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) is associated with a primary link and a non-primary link. The NSTR softAP MLD transmits, on only the primary link, a frame including a complete profile of the primary link and indicating a complete profile of the non-primary link. The respective complete profiles of the primary link and the non-primary link each include capabilities, operation parameters, and other discovery information. The frame can include fields and elements that carry the complete profile of the primary link, and can include a multi-link (ML) element that indicates the complete profile of the non-primary link. The NSTR softAP MLD can receive or determine an update to the operation parameters of the non-primary link, and can transmit, on the primary link, an indication of the update to the operation parameters of the non-primary link.

Abstract: This disclosure provides methods, components, devices and systems for access point (AP)-aided downlink transmission opportunity (TXOP) preemption by stations (STAs) with low-latency uplink traffic. Some aspects more specifically relate to how a STA transmits a preemption indication (PRI) associated with a signature of the STA and how an AP, via reception of signature-based PRIs, may obtain information relating to which specific STAs have low-latency traffic ready for uplink transmission. Such signatures may relate to a resource allocation, such as a tone pattern, used to transmit at least a portion of a PRI. In some examples, the AP transmits a preemption scheduling (PRS) frame that includes channel access information, for each of the STA(s) that sent a PRI, associated with a downlink TXOP of the AP. Such channel access information may include at least a grant of permission for STA(s) to attempt uplink preemption of the downlink TXOP.

Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.

The wireless station may receive a first beacon container according to a first periodicity and a second beacon container according to a second periodicity. The first and second periodicities may have different values based on the device type of the wireless station. The beacon containers may include type-specific segments corresponding to the device type. Each type-specific segment may include parameters or updated information for the wireless station.

Abstract: This disclosure provides methods, components, devices, and systems for enhanced data channel access (EDCA) for coordinated channel access. Some aspects more specifically relate to EDCA prioritization for accessing a wireless channel during restricted target wakeup time (rTWT) service periods (SPs). For example, a first wireless device may receive an indication of EDCA parameters defined for the first wireless device with respect to an rTWT SP of a second wireless device. In such examples, the first wireless may contend for access to a wireless channel during the rTWT SP of the second wireless device using the EDCA parameters according to the received indication. In some implementations, the second wireless device may broadcast a beacon including the EDCA parameters. In some other implementations, the second wireless device may transmit one or more rTWT negotiation messages including the EDCA parameters defined for the first wireless device.

Abstract: This disclosure provides methods, components, devices and systems for addressing client constraints in dynamic subchannel operation (DSO). Some aspects more specifically relate to a DSO frame exchange between an access point (AP) multi-link device (MLD) and a non-AP MLD that is operating in accordance with an enhanced multi-link single-radio (EMLSR) or an enhanced multi-link multi-radio (EMLMR) communication mode. In such aspects, the non-AP MLD may use a frame associated with a DSO frame exchange to trigger the non-AP MLD to perform an operation associated with the EMLSR/EMLMR communication mode. Some additional, or alternative, aspects more specifically relate to a DSO frame exchange between an AP MLD and a non-AP MLD that has disabled a communication mode associated with uplink multi-user (MU) communication. In such aspects, the AP MLD and the non-AP MLD may apply one or more constraints on the DSO frame exchange associated with the disabled uplink MU communication.

Some aspects more specifically relate to various formats of multi-link elements via which a non-access point (AP) multi-link device (MLD) may request the profile information associated with multiple AP MLDs and via which an AP MLD (or an AP affiliated with the AP MLD) may provide the requested profile information. In some examples, profile information associated with multiple AP MLDs may be requested or provided, or both, via a single multi-link element in accordance with one or more of the various formats. A non-AP MLD or an AP MLD may use such a single multi-link element to request or provide MLD-level information associated with the multiple AP MLDs or to request or provide link-level information associated with the multiple AP MLDs, or any combination thereof.
