Abstract: An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is to decode an MSDU received at a MAC layer of the STA, the MSDU including a data packet and descriptor metadata. A DSCP tag and launch time information are detected in the descriptor metadata. The launch time information indicates a desired transmission time of the data packet. The data packet is placed in a first transmission queue of a plurality of transmission queues of the MAC layer based on the DSCP tag. A scheduled transmission time of at least a second transmission queue of the plurality of transmission queues is determined to conflict with the desired transmission time. The scheduled transmission time is adjusted based on the launch time information. The data packet is encoded for transmission by the desired transmission time using a wireless communication channel.

Abstract: 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.

Abstract: For example, an Access Point (AP) may be configured to set a plurality of follow-up-information fields corresponding to a plurality of time domains. For example, the plurality of follow-up-information fields may include a first follow-up-information field and a second follow-up-information field. For example, the first follow-up-information field may include first time information corresponding to a first time domain, and the second follow-up-information field may include second time information corresponding to a second time domain. For example, the AP may be configured to transmit a time-measurement frame to a non-AP station (STA). For example, the time-measurement frame may be configured to include the plurality of follow-up-information fields.

Abstract: This disclosure describes systems, methods, and devices related to dynamic quality of service (QoS). A device may establish a stream classification service (SCS) identified by an SCS identification (SCSID). The device may generate a frame comprising an A-Control field to be sent to one or more station devices (STAs). The device may modify the A-control field to comprise one or more parameters associated with the SCS stream. The device may cause to send the frame to the one or more STAs.

Abstract: 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 OUT including an indication of an Ethertype protocol. The device may send the 802.11 frame using a wireless connection.
