For example, a wireless communication station (STA) may be configured to determine whether a stream of frames is suitable for out-of-order delivery from a first Medium Access Control layer (MAC-layer) process to a second MAC-layer process, the second MAC-layer process is above the first MAC-layer process; and, based on a determination that the stream of frames is suitable for out-of-order delivery, to deliver to the second MAC-layer process one or more frames of the stream of frames according to an out-of-order delivery scheme.

Apparatus, system, and method of out-of-order delivery of wireless communication frames

An extremely high-throughput (EHT) station (STA) encodes a management frame to include a quality-of-service (QoS) capability element that includes a QoS information field configured to signal QoS redundancy capability. The EHT STA may set a QoS redundancy bit in the QoS information field of the QoS capabilities element to indicate (i.e., signal) that the EHT STA supports redundancy for QoS data frames. The EHT STA may include an Extended Capabilities element in the management frame and set a new redundancy indicator bit in the Extended Capabilities element to indicate (i.e., signal) that the EHT STA supports redundancy for a select subset of IEEE802.11 management frames.

Signalling support for redundancy capabilities for EHT

Provided herein is ultra-low latency (ULL) PHY/MAC design for IEEE 802.11. The disclosure provides an apparatus, comprising: interface circuitry; and processor circuitry coupled with the interface circuitry, wherein the processor circuitry is to: encode a ULL packet; and cause transmission of the ULL packet to an Access Point (AP) via the interface circuitry in an unlicensed spectrum, wherein a duration of the ULL packet is less than 20 microseconds. Other embodiments may also be disclosed and claimed.

Ultra-low latency PHY/MAC design for IEEE 802.11

The application relates to ultra-low latency data transmission in Wireless Local Area Networks (WLANs). An apparatus used in a non-Access Point Station (non-AP STA), includes processor circuitry configured to cause the non-AP STA to, when there is urgent data that must be transmitted in uplink without waiting for a scheduled slot: generate a Protocol Data Unit (PDU) from the urgent data; and transmit the PDU on a resource unit pre-assigned for urgent transmission, wherein the resource unit is multiplexed for uplink transmission from multiple non-AP STAs.

Ultra-low latency data transmission in WLANs

The present disclosure is related to multi-queue management techniques and packet reordering techniques for inter-radio access technology (RAT) and intra-RAT traffic steering. The multi-queue management and packet reordering techniques may be used in Multi-Access Management Services (MAMS) framework, which is a programmable framework that provides mechanisms for the flexible selection of network paths in a multi-access (MX) communication environment, based on an application's needs. Other embodiments may be described and/or claimed.

Traffic steering and cross-layer and cross-link mobility management techniques for multi-access management services

For example, an apparatus may be configured to cause an Access Point (AP) Multi-Link Device (MLD) to, during an ongoing communication between a first AP of the AP MLD and a first non-AP wireless communication station (STA) over a first wireless communication channel, communicate a suspend request by a second AP of the AP MLD over a second wireless communication channel, the suspend request configured to request suspension of the ongoing communication between the first AP of the AP MLD and the first non-AP STA; to suspend the ongoing communication between the first AP of the MLD and the first non-AP STA over the first wireless communication channel for a suspension period; and to communicate a frame by the first AP over the first wireless communication channel during the suspension period, the frame communicated between the first AP and a second non-AP STA.

Apparatus, system, and method of suspending a wireless communication

This disclosure describes systems, methods, and devices related to latency reduction. The device may set up a plurality of links between an access point (AP) multi-link device (MLD) and a non-AP MLD. The device may encode a frame for transmission on a first link of the plurality of links between a first AP of the AP MLD and a first STA of the non-AP MLD. The device may identify an indication received at a second STA of the non-AP MLD using an interference mitigation signal. The device may cause to stop the transmission of the frame on the first link based on the indication. The device may identify a second frame on the first link received from the first AP. The device may cause to resume the transmission of the first frame on the first link.

Mechanisms to reduce the worst-case latency for ultra-low latency applications

This disclosure describes systems, methods, and devices related to using redundant frames for time-sensitive networking (TSN). A device may identify an Ethernet frame including a redundancy tag and an Internet Protocol (IP) packet; generate, based on the Ethernet frame, a first Wi-Fi frame including the redundancy tag and a sub-network access protocol (SNAP) header after an 802.11 medium access control (MAC) header and prior to the redundancy tag, the first Wi-Fi frame further including a first encapsulation of the IP packet; generate, based on the Ethernet frame, a second Wi-Fi frame including the redundancy tag and the SNAP header after the 802.11 MAC header and prior to the redundancy tag, the second Wi-Fi frame further including a second encapsulation of the IP packet; transmit the first Wi-Fi frame using a first Wi-Fi communication link; and transmit the second Wi-Fi frame using a second Wi-Fi communication link.

Enhanced redundancy over Wi-Fi for ultra-reliable wireless time-sensitive networking

This disclosure describes systems, methods, and devices related to ultra-low latency (ULL). A device may generate a first frame to be sent on a first link in a multi-link operation (MLO) with an multi-link device (MLD). The device may generate a second frame to be sent on a second link in the MLO with the MLD. The device may divide the first frame and the second frame into a first plurality of segments and a second plurality of segments separated by one or more first and second time gaps, respectively. The device may indicate to a first station device having a ULL packet to initiate a transmission of the ULL packet during an earliest time gap on the first link. The device may cause to send the one or more first and second plurality of segments on the first link and second link respectively.

Ultra-low latency medium access control design for 802.11

A multi-link device (MLD) configured for reporting per-port frame replication and elimination for reliability (FRER) capabilities uses a per-Port FRER-capabilities object generated by upper MLD MAC layer to indicate per-Port FRER capabilities of lower layers including lower MAC and PHY layers. The per-port FRER capabilities of the lower layers may be reported using the per-Port FRER-capabilities object to an upper layer such as an FRER layer. The per-Port FRER-capabilities object may indicate at least whether or not a port between the upper MLD MAC layer and the FRER layer supports frame replication and duplication elimination capabilities in the underlying MAC and PHY layers.

Multi-link device (MLD) for reporting per-port frame replication and elimination for reliability (FRER) capabilities using a per-port FRER-capabilities object

The present disclosure is related to Multi-Access Management Services (MAMS), which is a programmable framework that provides mechanisms for the flexible selection of network paths in a multi-access (MX) communication environment, based on an application's needs. Generic Multi-Access (GMA) functions are also integrated into the MAMS framework. The present disclosure discusses Per-Packet Prioritization (PPP), intra-flow classification, and Active Queue Management (AQM) techniques for MAMS/GMA systems. Other embodiments may be described and/or claimed.

Multi-access management service packet classification and prioritization techniques

A Quality-of-Service (QoS) Management AP is configured to support QoS Management features and to perform a QoS Management Protocol. The AP decodes an Enhanced Add Traffic Stream (E-ADDTS) Request QoS Action Frame (E-ADDTS Req) received from a station (STA) to initiate QoS setup for a traffic stream. The STA may be a QoS Management STA configured to support the QoS Management features and perform the QoS Management protocol. The AP may encode, for transmission to the STA in response to the E-ADDTS Req, an E-ADDTS Response QoS Action Frame (E-ADDTS Resp) which includes a status code to indicate whether the QoS setup has been accepted. When the QoS setup is accepted, the E-ADDTS Resp includes a QoS setup ID within a QoS setup ID field in the E-ADDTS Resp that uniquely identifies the QoS setup for the traffic stream.

Extensible enhanced QoS framework for signaling requirements

This disclosure describes systems, methods, and devices related to wireless time sensitive networking. A device may identify, using an 802.3 protocol stack, an 802.3 frame received from a second device using a wired Ethernet connection, and extract, using the 802.3 protocol stack, a redundancy tag from the 802.3 frame, the redundancy tag including a sequence number. The device may generate, using an 802.11 protocol stack, an 802.11 frame with a subnetwork access protocol (SNAP) field, the SNAP field including an organizationally unique identifier (OUI) and the sequence number, the OUI including an indication of an Ethertype protocol. The device may send the 802.11 frame using a wireless connection.

Frame replication and interfaces for time sensitive networking

A station may receive a frame transmitted to a plurality of stations (STAs). The frame may indicate a first frequency resource allocated for the STA and a second frequency resource allocated for another STA of the plurality of STAs. The STA may transmit a data frame using the first frequency resource and receive an acknowledgement frame that acknowledges receipt of the data frame. The STA may receive a multiple user request to send (MU RTS) frame transmitted to the plurality of STAs and may subsequently transmit a clear to send (CTS) frame in response to receipt of the MU RTS frame. The RTS/CTS transmissions may occur prior to transmission of the data frame.

Enhancements for resource allocation in WLAN systems

An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.
