Abstract: In one example, a transmitter wireless communication device may be configured to encode k data packets into n encoded packets according to a Network Coding (NC) scheme, wherein k is equal to or greater than two, and wherein n is greater than k. For example, the transmitter wireless communication device may be configured to transmit the n encoded packets over a plurality of wireless communication resources, for example, by transmitting at least one first encoded packet over a first wireless communication resource and transmitting at least one second encoded packet over a second wireless communication resource. For example, a receiver wireless communication device may be configured to determine the k data packets, for example, by decoding at least k received encoded packets out of the n encoded packets according to the NC scheme.

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.

Abstract: An apparatus of a station (STA) includes memory and processing circuitry coupled to the memory. The processing circuitry is to detect a first peer-to-peer (p2p) wireless communication link of the STA is active within a wireless TSN network. A wireless link information element corresponding to the first p2p wireless communication link is encoded for transmission to an AP. The wireless link information element includes at least one attribute of the first p2p wireless communication link. A gate control list (GCL) received from the AP is decoded. The GCL originates from a central network controller (CNC) of the wireless TSN network, and the GCL is based on the at least one attribute in the wireless link information element. Transmission and reception schedules of the first p2p wireless communication link are configured based on the GCL.

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: In one example, a transmitter wireless communication device may be configured to encode k data packets into n encoded packets according to a Network Coding (NC) scheme, wherein k is equal to or greater than two, and wherein n is greater than k. For example, the transmitter wireless communication device may be configured to transmit k encoded packets of the n encoded packets during a plurality of transmission slots within a Synchronized Transmit Opportunity (S-TxOP), e.g., by transmitting one or more encoded packets of the k encoded packets during a transmission slot of the plurality of transmission slots. For example, the transmitter wireless communication device may be configured to transmit m other encoded packets of the n encoded packets during one or more subsequent transmission slots within the S-TxOP, for example, based on a determination that m packets of the k encoded packets have not been successfully received.

Abstract: This disclosure describes systems, methods, and devices related to multi-user uplink channel sounding. A device may determine a channel sounding sequence with one or more access points (APs), wherein the channel sounding sequence comprises a null data packet announcement (NDPA) communicated with at least one of the one or more APs. The device may determine a first group of station devices (STAs) associated with a first basic service set (BSS). The device may cause to send a trigger frame to the first group of STAs to solicit an uplink NDP from each STA of the first group of STAs. The device may identify a first uplink NDP received from a first STA of the first group of STAs. The device may identify a second uplink NDP received from a second STA of a second group of STAs.

Abstract: A non-access point station (STA1) configured for transmission opportunity (TXOP) sharing operations in a wireless local area network (WLAN) may allocate time in a TXOP obtained by the STA1 to an access point station (AP) or another non-AP STA (STA2) using a Multi-User Request-To-Send Transmission TXOP sharing (MU-RTS TXS) trigger frame subvariant.

Abstract: A station (STA), when operating as a responding STA (RSTA) for time-synchronization of a plurality of initiating STAs (ISTAs) in a time-synchronized network (TSN), may determine, during a negotiation phase, whether each of the ISTAs that intend to participate in one or more measurement phases are requesting to be polled or are requesting not to be polled. For the ISTAs that are requesting to be polled, the RSTA may perform a polling phase prior to performing each of the one or more measurement phases. For the ISTAs that are requesting not to be polled, the RSTA may refrain from performing a polling phase prior to performing each of the one or more measurement phases. The RSTA can directly trigger the measurement phase for ISTAs that are requesting not to be polled. By grouping ISTAs into polling and non-polling groups, efficiency improvements are achieved.

Abstract: 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.
