Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

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: Certain aspects of the present disclosure provide a method for wireless communication at a wireless node, generally including communicating, via a first link, with a first access point (AP) device affiliated with a single mobility domain (SMD) entity, outputting, for transmission to the first AP device, a first message including a first indication that the wireless node is initiating a handover of the wireless node from the first AP device to a second AP device affiliated with the SMD entity, communicating with the second AP device via a second link during the handover after obtaining a second indication that context information has been transferred from the first AP device to the second AP device, and disabling the first link with the first AP device after obtaining a third indication that triggers the wireless node to disable the first link with the first AP device.

Abstract: Aspects relate to multi-link communication. In some examples, a communication frame carries a multi-link information element (ML IE). The ML IE includes a bitmap and one or more information sub-elements. In some examples, the bitmap indicates the links of a set of radio links to which the information sub-elements apply. In some examples, a frame may carry multiple ML IEs. In some examples, different ML IEs in the same frame may include the same bitmap, where the different ML IEs may carry different information sub-elements for the radio links indicated by the bitmap. In some examples, an ML IE serves to indicate that information sub-elements that are located in the frame body of the frame at a location that precedes the ML IE in the frame body apply to different radio links than the radio links indicated by the bitmap of the ML IE.

Abstract: An apparatus has a memory and one or more processors coupled to the memory. The processor(s) is configured to transmit a first message indicating a first machine learning capability of the first wireless device. The processor(s) is also configured to receive, from a second wireless device, a second message indicating a second machine learning capability of the second wireless device. The processor(s) is further configured to communicate information associated with a machine learning model for use between the first wireless device and the second wireless device based at least in part on the second machine learning capability and the first machine learning capability. The processor(s) is also configured to communicate with the second wireless device based at least in part on the machine learning model.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the “r-TWT link”). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.

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: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

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: 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.
