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.

Abstract: A transmitting (Tx) access point (AP) multi-link device (MLD) may be configured to designate a parent ML element and at least one child ML element in the network management frame, e.g., the beacon frame or probe response frame, and at least one non-AP MLD may be configured to receive the network management frame and apply the parent ML element to the child ML element.

Abstract: This disclosure provides methods, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), within a 3.5 GHz bandwidth. In some examples, the AP may generate a first advertisement frame comprising information configured to enable one or more communication devices to associate with the apparatus for wireless communications via a first channel in a first operating band. In some examples, the AP may output the first advertisement frame for transmission according to a first periodic interval.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling parameters for peer-to-peer communications in a wireless network. One aspect provides a method for wireless communications at an access point (AP). The method generally includes: obtaining, from an access point (AP), a transmission opportunity (TXOP) sharing trigger indicating a duration in which a TXOP is shared by the wireless station and one or more other devices; relaying, to the one or more other devices, information identifying parameters for wireless communications between the wireless station and the one or more other devices; and during the TXOP, communicating with the one or more other devices based on the parameters for wireless communications between the wireless station and the one or more other devices.
