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

Some demonstrative embodiments may include apparatus, system and method of scheduling Time Sensitive Networking (TSN) wireless communications. For example, an apparatus may include logic and circuitry configured to cause a wireless communication Access Point (AP) to allocate at least one Time Sensitive Networking (TSN) enabled (TSN-enabled) Target Wakeup Time (TWT) Service Period (SP) based on one or more timing requirements of a TSN schedule of at least one TSN stream for at least one wireless communication station (STA); to transmit a TWT scheduling message to schedule the TSN-enabled TWT SP, the TWT scheduling message including an indication that the TSN-enabled TWT SP is restricted to only TSN communications; and, during the TSN-enabled TWT SP, to communicate one or more frames of the at least one TSN stream with the at least one STA.

Apparatus, system and method of restricted target wake time (TWT) service period (SP) for sensitive traffic

The application provides a method, method, comprising: a station (STA) sending a first quality of service (QoS) request message to an access point (AP) indicating a requested QoS for a traffic stream from the AP to the STA; the AP receiving the first QoS request message from the STA and sending a first traffic stream applied with the requested QoS to the STA when the requested QoS matches with an existing QoS policy for the STA in the AP or there is no existing QoS policy for the STA in the AP, and the STA receiving the first traffic stream applied with the requested QoS from AP.

Method and apparatus used in WLAN networks

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

Systems, apparatuses and methods may provide for technology that detects one or more non-compliant nodes with respect to a timing schedule, detects one or more compliant nodes with respect to the timing schedule, and identifies a malicious node based on positions of the one or more non-compliant nodes and the one or more compliant nodes in a network topography. The non-compliant node(s) and the compliant node(s) may be detected based on post-synchronization messages, historical attribute data and/or plane diversity data.

Attacker localization based on tracking anomaly propagation in 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.
