    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 systems, methods, and apparatuses for associating a wireless communication device such as a wireless station (STA) of a STA multi-link device (MLD) with an access point (AP) MLD that includes a first AP associated with a first communication link of the AP MLD and includes one or more secondary APs associated with one or more respective secondary communication links of the first AP MLD. The first AP includes one or more virtual APs, and the first AP and the one or more virtual APs of the first AP belong to a first multiple basic service set identifier (BSSID) set associated with the first communication link. The AP MLD transmits a frame including a first element carrying discovery information for the first AP and the one or more virtual APs belonging to the first multiple BSSID set, and including a second element carrying discovery information for the one or more secondary APs of the first AP MLD associated with the one or more respective secondary communication links of the first AP MLD.

    Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support clear channel assessment adjustment for in-band link aggregation. Generally, the described techniques provide for improved handling of adjacent channel interference in multi-link aggregation scenarios. In accordance with the described techniques, a device may establish a set of wireless links for communication with a second device, the set of wireless links supporting parallel transmission during at least a first duration of a multi-link session, the set of wireless links including at least a first wireless link and a second wireless link. The device may identify a parameter value modifying a channel availability threshold to use during a channel access procedure for a first wireless channel of the first wireless link based on a presence of the second wireless link. The device may perform the channel access procedure for the first wireless channel based on the identified parameter value.

    Abstract: A method and an apparatus for wireless communication are provided. In one configuration, an apparatus is configured to transmit a wake-up radio (WUR) signal, to determine to transmit a second signal within a SIFS after transmitting the WUR signal to increase medium reuse, and to transmit the second signal within the SIFS after transmitting the WUR signal based on the determination. The second signal may be a data, management, control, ACK, or CF-end frame to enable legacy devices that do not decode the WUR signal to avoid wasted airtime cause by EIFS after the WUR signal. In another configuration, the apparatus is configured to transmit a CTS-to-self frame, to determine to transmit a second signal within a SIFS after transmitting the CTS-to-self frame, and to transmit the second signal based on the determination. The second signal may be a WUR signal or an intermediate signal followed by a WUR signal.

    Abstract: A first AP in a wireless network determines that a wireless client device should re-associate from the first AP to a second AP of the wireless network. The first AP communicates an AP coordination message from the first AP to the second AP to share coordination information with the second AP. The first AP coordinates with the second AP to cause the re-association of the wireless client device in accordance with the coordination information. The first and second AP may coordinate directly to synchronize re-association activities. Re-association activities may include the use of a configuration message to the wireless client device, managing transmit power of beacon messages from the first and second APs, or forced disassociation and blocking. The first AP may maintain a record of which re-association activity was successful in causing the wireless client device to re-associate to the second AP.

    Abstract: In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.
