Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) is associated with a primary link and a non-primary link. The NSTR softAP MLD transmits, on only the primary link, a frame including a complete profile of the primary link and indicating a complete profile of the non-primary link. The respective complete profiles of the primary link and the non-primary link each include capabilities, operation parameters, and other discovery information. The frame can include fields and elements that carry the complete profile of the primary link, and can include a multi-link (ML) element that indicates the complete profile of the non-primary link. The NSTR softAP MLD can receive or determine an update to the operation parameters of the non-primary link, and can transmit, on the primary link, an indication of the update to the operation parameters of the non-primary link.

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 apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

Abstract: This disclosure provides methods, devices and systems that facilitate mobility of wireless communication devices configured for multi-link operation (MLO). Particular aspects more specifically relate to facilitating fast basic service set (BSS) transitions by wireless communication devices that support MLO. For example, some aspects provide support for station (STA) multi-link device (MLD) roaming between access point (AP) MLDs, from an AP MLD to a non-MLO AP, or from a non-MLO AP to an AP MLD. In some aspects, a STA MLD may be configured to use a medium access control (MAC) service access point address (MAC-SAP address) of the AP MLD when re-associating or communicating with a legacy AP or with an AP MLD. In such aspects, the MAC-SAP address may be used by all STAs of the non-AP MLD for fast BSS transitions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive a management frame addressed to the receiver device; parse the management frame to identify a link identifier included in the management frame; associate the link identifier with link information included in the management frame; and update, based at least in part on the link information, a communication configuration for a link identified by the link identifier. Numerous other aspects are provided.

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: Disclosed are methods and systems for a wireless communication network including detecting a trigger to switch a serving channel at a first access point, and communicating a first channel switch message from the first access point to a second access point. The first access point may be in a downstream and/or upstream or communication flow in relation to the second access point. The process may include communicating a first Channel Switching Announcement (CSA) message from the second access point to at least one client of the second access point, where the least one client is one of a plurality of clients receiving internet connectivity through a series of communication flows including a data flow through the second access point. The process further includes revising a time to switch channel information included in the first channel switch message, where the first CSA message includes the revised time to switch channel information.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may broadcast or multicast a wakeup transmission to wakeup radios (WURs) of a group of wireless and determine to retransmit the first wakeup transmission (e.g., for redundancy). The AP may transmit a second wakeup transmission to the WURs, the second wakeup transmission including an indication that the second wakeup transmission is a retransmission of the first wakeup transmission. The wireless devices may receive the indication that the second wakeup transmission is a retransmission, and may power up a main radio to receive a beacon based on whether or not the previous or originally wakeup transmission was received (e.g., determined via the indication included in the received wakeup message). In some cases, the AP may identify that some wireless devices failed to receive the first wakeup transmission, and may transmit a second wakeup transmission to those identified stations.

Abstract: A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.
