Abstract: Methods, systems, and devices for wireless communication are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support a 20 MHz station (STA) parked on a secondary channel. Without the described techniques, mechanisms to support secondary channel operation may be unable to receive management frames or broadcast traffic from an access point (AP), which may cause the STA to lose synchronization with the AP, miss a channel change or other critical announcement from the AP, etc. Considerations for providing such information to STAs parked on a secondary channel are discussed. In some examples, an AP may restrict resource unit allocation to the secondary channel on which the STA is parked. In some cases, a trigger-based random access mechanism may utilize aspects of the present disclosure to limit access to certain resource units to STAs on a given secondary channel.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless device may advertise communication parameters for a particular frequency band over another frequency band. In one example, a wireless device generates multi-band wrapper information element or a neighbor report information element, which may include one or more subelements, each conveying communication information for a particular frequency band. The wireless device may include the multi-band wrapper information element or the neighbor report information element in a management frame and may transmit the management frame over a first frequency band. Another wireless device may receive the management frame over the first frequency band and may obtain the communication information for other frequency bands from the included multi-band wrapper information element. In some cases, a subelement carries communication information that is sufficient for the receiving device to directly associate with the transmitting device over the other frequency bands.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) and orthogonal-frequency-division-multiple access (OFDMA) techniques for sharing the time or frequency resources of a transmission opportunity (TXOP). According to such techniques, an AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time or frequency resources with other selected APs. To share its resources, the winning AP may partition the TXOP into multiple time or frequency segments each including respective time or frequency resources representing a portion of the TXOP, and allocate each of the time or frequency segments to itself or to one of the selected APs.

Abstract: This disclosure provides methods, components, devices and systems for multiple access point (AP) association with a single station (STA) to provide a seamless transition (e.g., little to no service interruption during an active link transfer). Some aspects more specifically relate to a multi-link entity (MLE) and multiple AP members of the MLE, and their communications with the STA.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at an access point (AP) device, generally including generating a first frame that indicates updated roles associated with at least two basic service set IDs (BSSIDs) of a multi-BSSID set, wherein the updated roles relate to whether a BSSID is a transmitted BSSID (TxBSSID) or a nontransmitted BSSID (nonTxBSSID) and outputting the first frame for transmission.

Abstract: This disclosure provides methods, devices, and systems for communicating cross-link multi-link signaling (MLS) control signaling in wireless local area networks (WLANs). In various aspects, an apparatus may generate a frame that includes a header including an MLS subfield that includes a set of bits associated with a respective link of a set of links between the first MLD and a second MLD. The apparatus may configure a signaling type (s-type) of the MLS subfield with a value indicating a type of MLS control signaling associated with the MLS subfield, and may configure each bit of a first subset of bits of the MLS subfield with a value indicating that the type of MLS control signaling is applicable to the respective link associated with the bit. Further, the apparatus may output the first frame for transmission to the second MLD on a first link of the set of links.

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 systems and methods for synchronizing wireless devices with each other. In some implementations, a device transmits, to at least one wireless station (STA), an indication of an enhanced synchronization mode on a first communication link associated with a first access point (AP) of the device. The device transmits, during the enhanced synchronization mode, a plurality of sync frames on the first communication link more often than Target Beacon Transmission Times (TBTTs) associated with the first communication link, each of the plurality of sync frames indicating a Timing Synchronization Function (TSF) offset between the first AP and a second AP of the device. In some instances, at least one of the plurality of sync frames may be a Fast Initial Link Setup (FILS) Discovery frame carrying a TSF value of the first AP.
