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: 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.

Abstract: A first Multi-AP device configured as a Multi-AP Agent transmits, to a second Multi-AP device configured as a Multi-AP Controller over a first communication link, a Device Provisioning Protocol (DPP) Configuration Request Message indicating multi-link operation (MLO) capabilities of the first Multi-AP device. The first Multi-AP device receives, from the second Multi-AP device over the first communication link, a DPP Configuration Response Message indicating MLO association information responsive to the indicated MLO capabilities, and establishes a backhaul path with a third Multi-AP device, configured as a second Multi-AP Agent, on the first communication link and one or more second communication links according to the MLO association information. The MLO capabilities may be indicated in a DPP Configuration Object of the DPP Configuration Request Message, and the MLO association information may be indicated in a multi-link device (MLD) address field of a DPP Configuration Object of the DPP Configuration Response Message.

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: 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: The present disclosure provides techniques for rate adaptation in multi-user multiple-input-multiple-output (MU-MIMO) systems for wireless local area networks (WLANs). When rate adaptation is based solely on packet error rate (PER) from feedback provided by wireless stations (STAs), the rate selection may not be optimal. In some scenarios, rate adaptation from the combined use of PER and MU signal-to-interference-plus-noise ratio (MU-SINR) can allow for better selection of the rate components, such as modulation coding scheme (MCS) and number of spatial streams (Nss). Accordingly, the present disclosure provides techniques in which a condition associated with transmitting an MU PLCP Protocol Data Unit (MU-PPDU) for multiple STAs is identified, packet error (e.g., PER) and signal strength (e.g., MU-SINR) metrics are determined for each STA in response to such condition, a rate for each STA is determined based on the respective metrics, and the MU-PPDU is transmitted according to the determined rates.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for extending the range of a personal audio device connected to a personal wireless communication device via enabling the personal audio device to connect to and communicate with the personal wireless communication device via an access point (AP). An AP may have a larger range than a personal wireless communication device, and accordingly, an AP may be used to stream audio or voice calls to the personal audio device when the direct link quality between the personal audio device and the personal wireless communication device is below a threshold. To reduce latency and packet loss associated with transitions between communicating with the personal wireless communication device directly and via the AP or transitions between multiple APs, the personal audio device may be configured to establish a new wireless communication connection before breaking a current wireless communication connection.

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: Various aspects provide a wireless station (STA) to implement congestion sensitive target wake time (TWT) communications scheduling and enable the STA to determine whether to engage in communications between TWT service periods. A method described includes identifying a congestion metric, determining whether the congestion metric meets a congestion threshold, and transmitting a request to establish TWT communications in response to determining that the congestion metric meets the congestion threshold. Another method described includes terminating a scheduled service period of a TWT communications, receiving an indication that a threshold number of frames is available for transmission to an STA from an access point (AP) or an indication that one or more frames are present in a transmission queue at the STA, and transmitting, by the STA to the AP an indication that a communications link is to remain active between the terminated scheduled service period and a subsequent scheduled service period.
