    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 enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information.

    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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

    Abstract: Methods, systems, and devices for wireless communications are described. 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 modify a transmission parameter for the first wireless link or a clear channel assessment (CCA) parameter for the second wireless link, or a combination thereof. The device may then perform the CCA procedure on the second wireless link and transmit at least a first portion of the message on the first wireless link based on the modified transmission parameter or modified CCA parameter.

    Abstract: Various aspects of the techniques, methods and devices described in this disclosure relate generally to achieving coexistence between WLAN and P2P networks, and specifically, to coordinated D2D communications. Some aspects particularly involve extending the capabilities of TWT elements transmitted by APs to support periodic reserved access windows during which D2D-enabled wireless devices are permitted to transmit direct wireless communications. Some other aspects relate to sharing time and frequency resources via CAP TDMA or CAP OFDMA techniques, and specifically, to allocating at least some of the time and frequency resources specifically for D2D communications. Some other aspects relate to periodic coordinated access windows during which APs are scheduled to contend but during which D2D devices are not permitted to contend, and specifically, to scheduling a reserved access window within a periodic coordinated access window during which D2D devices may transmit direct communications to other D2D devices despite the permissions associated with the periodic coordinated access windows.

    Abstract: This disclosure provides systems, methods and apparatuses for advertising discovery information of an AP in one or more downlink (DL) transmissions. In some implementations, the AP may allocate a dedicated resource unit (RU) for advertising discovery information of the AP to stations not associated with the AP, and may allocate one or more additional RUs for DL transmissions to one or more stations associated with the AP. The AP may transmit a multi-user (MU) packet containing discovery information intended for the unassociated stations and containing non-discovery-related information intended for the one or more associated stations. The discovery information may be transmitted on the dedicated RU, and the non-discovery-related information may be transmitted on the one or more additional RUs.
