    Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.

    Abstract: This disclosure provides systems, methods and apparatuses for wireless communications. In some implementations, a first access point (AP) may identify other APs to participate in a coordinated access point transmission session, may obtain a transmit opportunity (TXOP) for transmitting wireless signals over a frequency bandwidth, may allocate corresponding portions of the frequency bandwidth to the identified APs for downlink (DL) transmissions during the TXOP, may select a duration of the TXOP for the coordinated access point transmission session based at least in part on an amount or percentage of the first AP's frequency bandwidth that is allocated to the one or more identified APs for the coordinated access point transmission session, and may output information indicative of at least one of the selected TXOP duration or the corresponding portions of the frequency bandwidth allocated to the respective identified AP by the first AP.

    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication performed by a wireless communication device. An example wireless communication device includes an access point (AP) multi-link device (MLD). The AP MLD transmits a beacon frame to a wireless station (STA) MLD, the beacon frame including a plurality of AP medium access control (MAC) addresses of respective APs belonging to the AP MLD. The AP MLD receives an association request from the STA MLD, the association request including a plurality of STA MAC addresses of respective STAs belonging to the STA MLD. The AP MLD generates, during a handshake operation with the STA MLD, one or more encryption keys configured to encrypt communications between the AP MLD and the STA MLD. The AP MLD verifies the plurality of STA MAC addresses based at least in part on the one or more encryption keys.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for onboarding one or more Multi-AP devices using a device provisioning protocol (DPP) and a Multi-AP communication protocol. In one aspect, a first Multi-AP device may determine, during an onboarding process, DPP configuration information that was derived using the DPP. The first Multi-AP device may establish a Multi-AP network configuration between the first Multi-AP device and a second Multi-AP device using the Multi-AP communication protocol based, at least in part, on the DPP configuration information. In one aspect, the DPP configuration information may be derived remotely by the network operator prior to device deployment. In one aspect, a configurator station (STA) may be delegated as the DPP configurator by the network operator, and may onboard one or more STAs into the Multi-AP network using the DPP and the Multi-AP communication protocol.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer-readable media, for steering an association of a device in a network having multiple access points (APs). In one aspect, a first AP can obtain per-AP metric information regarding a plurality of other APs in the network. The per-AP metric information may include backhaul performance information regarding at least one wireless backhaul channel in the network. The per-AP metric information may include an estimated air time fraction value reported by the other APs. A selection to steer the device from the first AP to a second AP can be based, at least in part, on the per-AP metric information. In some implementations, a Multi-AP Controller can redistribute per-AP metric information collected from multiple APs in the network. In some implementations, a topology of the network may be optimized by steering a child AP to another wireless backhaul link.
