Abstract: This disclosure provides methods, components, devices and systems for coordinated medium access period management for overlapping basic service sets (OBSSs). Some aspects more specifically relate to coordinated medium access between access points (APs) and stations (STAs) of an OBSS. In some examples, a first STA may monitor, over one or more medium access periods, for communications between a neighbor AP and one or more second STAs. The one or more medium access periods may be configured for medium access and resource reservation for communications between the neighbor AP and the one or more second STAs. In some examples, the first STA may transmit to an associated AP, a report indicating the one or more attributes associated with the monitoring over the one or more medium access periods. In some examples, the report may be solicited or unsolicited, and the STA may monitor for communications over one or more measurement windows.

Abstract: This disclosure provides methods, components, devices, and systems that support information exchanges for coordinated access point (CAP) operations. Some aspects more specifically relate to transmitting and receiving CAP-specific parameters to facilitate transmit opportunity (TXOP) sharing between a first access point (AP) and one or more second APs. For example, the first AP (such as a sharing AP) may use CAP-specific parameters provided by the one or more second APs (such as shared APs) to determine a CAP sharing schedule for a TXOP. The CAP-specific parameters may include static capability parameters and dynamic parameters. The static capability parameters may include supported CAP modes, association identifiers (AIDs), and processing times, while the dynamic parameters may include medium access demands, traffic priority information, and service period information. The first AP may advertise the CAP sharing schedule to the one or more second APs via an announcement frame.

Abstract: This disclosure provides methods, components, devices, and systems for enhanced downlink (DL) data delivery. Some aspects more specifically relate to reducing the latency and power consumption associated with delivering DL buffered units (BUs) to stations (STAs) in an enhanced delivery mode. In some implementations, an access point (AP) may transmit an indication of queue information associated with one or more pending DL BUs for a STA. The AP may identify a set of operational parameters to use for transmission of the one or more pending DL BUs in accordance with the queue information. Likewise, the STA may identify a set of operational parameters to use for reception of the one or more pending DL BUs in accordance with the queue information. The AP may transmit the one or more pending DL BUs to the STA in accordance with the queue information and the set of operational parameters.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications. In one aspect, an apparatus may obtain, for a first access point (AP), a first service set identifier (SSID) associated with single-link communications and obtain, for a second AP, a second SSID associated with multi-link communications. The apparatus may obtain, from a wireless communication device, a management frame include a multi-link operation information field that carries a first SSID and obtain a multi-link indication for the wireless communication device based, at least in part, on the first SSID, the multi-link indication indicating whether the wireless communication device includes AP capable of link aggregation, and selectively associate with the wireless communication device based on the multi-link indication.

Abstract: This disclosure provides methods, components, devices and systems for machine learning models for spatial reuse. Some aspects more specifically relate to machine learning (ML) models for spatial reuse (SR). In some aspects, an access point (AP) may transmit ML model information to a station (STA). The ML model information may include an indication of an ML model, one or more parameters defining the ML model, one or more inputs for the ML model, one or more outputs for the ML model, or any combination thereof. A transmitting device may generate one or more inputs for the ML model, which may be local measurements or observations, input values indicated by one or more other STAs, information provided by an AP, one or more inferences (such as a candidate SR parameter value, or candidate action), or a combination thereof.

Abstract: This disclosure provides methods, components, devices and systems for performing actions to reduce end-to-end latency during a transmission of an encrypted payload of a medium access control (MAC) protocol data unit (MPDU) from a root access point (AP) to a wireless station (STA) via a satellite AP. For example, the satellite AP may be configured to receive the encrypted payload from the root AP, and then forward the received encrypted payload to the wireless STA, without decrypting the received encrypted payload and re-encrypting unencrypted payload at the satellite AP.

Abstract: Techniques for improved spatial reuse for wireless local area network (WLAN) networks are described. An access point (AP) may win a contention to a wireless medium and obtain a transmission opportunity (TXOP). The AP may perform a procedure to identify a group of un-managed APs for participation in spatial reuse opportunities for synchronous transmission over the TXOP. The AP may perform the procedure using over-the-air signaling. The AP may transmit a spatial reuse (SR) poll frame to one or more un-managed APs of the network, either sequentially or as part of a multiple-AP procedure. The AP may receive an SR response frame, or directly measure potential interference of a station (STA) serviced by one or more un-managed APs, and select a group of APs for coordinated reuse over the TXOP. The AP may select the group of APs based on one or more criteria for coordinated reuse.

Abstract: This disclosure provides methods, components, devices and systems for performing actions related to maximum allowed and active links at an access point (AP) multilink device (MLD) for each client. An example method performed by an AP MLD includes outputting, for transmission, a first frame indicating at least one of: a first limit on an allowed number of links for association with a multi-link device (MLD) with which the apparatus is affiliated, or a second limit on a number of allowed active links, obtaining, from a client, a request to associate one or more links between the client and the AP MLD, and processing the request subject to at least the first limit.

Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication at a wireless node, generally including communicating, via a first link, with a first access point (AP) device affiliated with a single mobility domain (SMD) entity, outputting, for transmission to the first AP device, a first message including a first indication that the wireless node is initiating a handover of the wireless node from the first AP device to a second AP device affiliated with the SMD entity, communicating with the second AP device via a second link during the handover after obtaining a second indication that context information has been transferred from the first AP device to the second AP device, and disabling the first link with the first AP device after obtaining a third indication that triggers the wireless node to disable the first link with the first AP device.
