摘要： 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.

摘要： 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.

摘要： This disclosure describes systems, methods, and devices related to time-sensitive networking in wireless communications. A device may exchange time-sensitive networking (TSN) capabilities with one or more station devices associated with the device. The device may identify a TSN capability request received from a TSN management entity associated with a TSN domain. The device may transmit a TSN capability response to the TSN management entity. The device may identify a TSN capability configuration frame from the TSN management entity. The device may configure the TSN capabilities based on the TSN capability configuration frame.

摘要： 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.

摘要： 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.

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.

摘要： An apparatus may be configured to perform communication over a millimeterWave (mmWave) channel assisted by communication over a sub 10 Gigahertz (GHz) (sub-10 GHz) channel. For example, a wireless communication device may be configured to identify a link block event including a blocking of an mmWave wireless communication link between an mmWave wireless communication station (STA) of the wireless communication device and an other wireless communication device. For example, the wireless communication device may be configured to, based on the link block event, communicate with the other wireless communication device over a sub-10 GHz wireless communication link between a sub-10 GHz STA of the wireless communication device and the other wireless communication device.
