Abstract: This disclosure provides methods, devices and systems for soliciting trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). Some implementations more specifically relate to trigger frame designs that support non-legacy TB PPDU formats. In some aspects, a trigger frame may carry information to be included in a physical layer (PHY) preamble of a TB PPDU solicited by the trigger frame. For example, the information may indicate values of one or more subfields of a universal signal field (U-SIG) associated with the non-legacy TB PPDU format. In some aspects, the information may be carried in a special user information field of the trigger frame. For example, the special user information field may be identified by a special association identifier (AID) value. The special AID value may be different than any AID values assigned to wireless communication devices in a basic service set (BSS) associated with the TB PPDU.

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 describes systems, devices, apparatus, and methods, including computer programs encoded on storage media, for controlling a network with one or more access points (APs). A controller may be configured to schedule at least some resources of the one or more APs to improve network efficiency. The APs may measure and report a variety of information and statistics to the controller. The controller may determine one or more transmission parameters and one or more operations a given AP is permitted to perform during a respective time interval. The controller may communicate the one or more transmission parameters using an indication, such as a message. At least one AP associated with the controller may communicate with stations (STAs) using the one or more transmission parameters.

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 AP MLD transmits a frame including an advertising information element carrying discovery information for the first AP of the AP MLD, including a first portion carrying discovery information for each secondary AP of the one or more secondary APs of the AP MLD, and including a second portion carrying common attributes of the one or more secondary APs of the AP MLD.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may establish a wakeup radio listen schedule for a station (STA) such that a wakeup radio of the STA is powered on to listen for wakeup messages according to wakeup signals transmitted by the AP (e.g., to power on a primary radio). The AP may identify synchronization information such as clock, interval, and offset information for the wakeup radio listen schedule, and may transmit the synchronization information to the STA, such that the STA may synchronize the wakeup radio for wakeup messages. In some cases, the STA may monitor for the synchronization information using a primary radio (e.g., from periodic beacon signals sent by the AP). In other cases, the STA may receive synchronization information in a wakeup signal (e.g., using the wakeup radio). In some examples, the STA may indicate a preferred synchronization mechanism in advance.

Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for determining or identifying a client device that is monopolizing a channel associated with a first basic service set (BSS). Once identified, a second BSS is dynamically created and configured with parameters that are throttled with respect to the first BSS. The client device is steered to the second BSS and is prevented from reassociating with the first BSS until a change in device status.

Abstract: Methods and apparatuses for reducing interference with co-located radio access technologies (RATs) are described herein. A method includes identifying, by an access point (AP), scheduling information for transmissions to a wireless device for a first RAT and setting a schedule of transmissions from the AP to the wireless device in a second RAT based at least in part on the scheduling information to avoid downlink transmission times for the first RAT. Another example method includes identifying, by a wireless device, scheduling information for transmissions to the wireless device for a first RAT. The method also includes determining a proximities of the wireless device to a first network device of the first RAT and to a second network device of a second RAT. The method further includes forwarding the scheduling information to the second network device of the second RAT based at least in part on the determining the proximities.

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: A headless device does not have a user interface that conveniently allows the user to enter a custom name for the headless device. In this disclosure, a custom name may be determined (either automatically or via user input) at a user device, such as a user device that has a user interface. The custom name may be based on the type of device, location, services, and/or other information about the headless device. The custom name is introduced to the communications network in association with a network address of the headless device. In some embodiments, forged messages based on conventional network protocols may be used to associate the custom name with the network address of the headless device.

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.
