    Abstract: This disclosure provides systems, methods, and apparatuses for allocating wireless resources to a multiple basic service set identifier (BSSID) set including a number of BSSIDs each associated with a corresponding one of a number of access points (APs). An AP may allocate random access resources for use by stations belonging to the multiple BSSID set using a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element. The AP may transmit a trigger frame containing the number of AID values to the stations belonging to the multiple BSSID set.

    Abstract: An access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field, one or more secondary change sequence fields, and a critical update flag subfield. The first change sequence field carries a value of the most-recent critical update for the first AP. The one or more secondary change sequence fields carry values of the most-recent critical updates for the one or more respective secondary APs. The critical update flag subfield carries an indication of a change in value of at least one of the secondary change sequence fields. The first AP transmits the frame over the first communication link of the AP MLD.

    Abstract: A first access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field and one or more secondary change sequence fields. The first change sequence field indicates a presence or absence of a critical update associated with the first communication link, and each of the one or more secondary change sequence fields indicates a presence or absence of a critical update associated with a corresponding secondary communication link of the AP MLD. The first AP of the AP MLD transmits the frame over the first communication link of the AP MLD to a station (STA) of a STA MLD.

    Abstract: This disclosure provides methods, devices and systems for sharing time resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) techniques for sharing the time resources of a transmission opportunity (TXOP). According to such techniques, a coordinated AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time resources with other coordinated APs. To share its time resources, the winning AP may partition the TXOP into multiple TXOP segments each including respective time resources representing a sub-duration of the TXOP. For example, the winning AP may assign, grant or allocate (hereinafter used interchangeably) itself one or more of the time resources and also allocate each of one or more remaining time resources to one or more other ones of the coordinated APs.

    Abstract: Methods and systems for accessing networks prohibit uncontrolled communications over a designated network. In some aspects, a method of controlling network access is disclosed. The method comprises transmitting, by a first access point, a first beacon over a first network to a station, the first beacon including information allowing the station to associate with the first access point. The method also comprises receiving a probe request at the first access point over the first network from the station, the probe request including a request for rules for associating with a second network. The method additional comprises generating a probe response to include the rules regarding associating with the second network, wherein the rules do not permit uncontrolled communications over the second network. The method further comprises transmitting the probe response from the first access point to the station over the first network.

    Abstract: Various aspects of the disclosure relate to communication using a wakeup frame for multiple service sets. For example, a single wakeup frame may be used to wakeup different sets of STAs served by different basis service sets (BSSs). To this end, the wakeup frame may include: an indication of whether the frame is for a single service set or multiple service sets, at least one wakeup field (e.g., one for each service set), an indication of the number of wakeup fields in the frame, or any combination thereof.

    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one configuration, the apparatus may be configured to determine when to send an acknowledgment (ACK) frame, a block ACK frame, and/or an all-ACK frame in response to receiving a frame/physical layer convergence procedure (PLCP) protocol data unit (PPDU). In another configuration, the apparatus may be configured to resolve ambiguous confirmation message information. In another configuration, the apparatus may be configured to use an MPDU delimiter to indicate acknowledgement policy.
