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: 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.

Abstract: Systems and techniques for locating a radio transmission source by scene reconstruction are described herein. A multipath radio signal—comprised of two or more multipath components—may be received at an antenna array. A collection of angle-of-arrival (AoA) values may be created from the multipath components. Thus, each AoA in the collection corresponds to one of the multipath components. An optical image of the environment may be obtained and possible reflective surfaces for the multipath components identified in the optical image. A set of paths may be created in a model of the environment by backtracking from the antenna array along the AoAs in the collection of AoA values. Here, the backtracking simulates reflections of the ray off of the surfaces identified in the optical image. A transmitter of the multipath radio signal may then be located via the set of paths.

Abstract: Various systems and methods for identifying and performing authentication of visible light communications using optical camera communication techniques are described. In an example, an electronic processing system to authenticate a particular light emitting source includes electronic operations for: detecting, from image data, modulated light data emitted from a light emitting object, where the image data depicts the light emitting object, and where the image data is captured with an image sensor (e.g., of a camera); identifying, from the image data, the light emitting object as a source of the modulated light data; receiving an indication to select the light emitting object as an authenticated source of the modulated light data; and performing a command to process the modulated light data from the authenticated source, with the command performed in response to the indication to select the light emitting object as the authenticated source of the modulated light data.

Abstract: The present invention relates to the preparation and activation of multimetallic zeolites loaded with transition metals for N2O abatement in tail-gases from different sources. The N2O-containing gas is brought in contact with a catalyst comprising Fe and a second, third, or any additional transition metal (Cu, Co, Ni, Mn, Cr, V), with a total metal content ranging from 0.1-1.0 wt. %, on a zeolite support (MFI or BEA) at 523-873 K. Not 10 only the combination and loading of metals, but also the method of incorporation in the zeolite and its activation is essential to obtain active and stable catalysts. The synergy between metals was observed in Fe—Cu, Fe—Co, and Fe—Co—Cu systems, but not with combinations of iron with other transition metals. The optimal catalysts show high N2O conversions (>80%) at temperatures 2000 hours in pilot-scale tests with a zeolite-coated monolithic reactor.

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.
