Abstract: This disclosure provides methods, components, devices, and systems for ultra-high reliability (UHR) signaling design. Some aspects more specifically relate to an access point (AP) transmitting a frame including a user info field to a wireless station (STA), where the user info field supports UHR parameters.

A STA receiving the trigger frame may determine a global CSD index corresponding to the STA according to the order of the user info fields.

Abstract: A system may identify lane lines (e.g., from sensor data) for autonomous vehicle control. The approach works by detecting individual lane line segments and identifying center lines that run along the length of each segment. By connecting these center lines, the system reconstructs complete lane lines. The identified lane lines then inform control operations for the machine. The sensor data may come from cameras, LIDAR, or RADAR. The system can be implemented in various forms, including systems-on-chip, autonomous vehicle control systems, or cloud-based platforms. The machine performing these operations may be autonomous or semi-autonomous, to perceive lane markings and navigate accordingly.

Abstract: An HD map system represents landmarks on a high definition map for autonomous vehicle navigation, including describing spatial location of lanes of a road and semantic information about each lane, and along with traffic signs and landmarks. The system generates lane lines designating lanes of roads based on, for example, mapping of camera image pixels with high probability of being on lane lines into a three-dimensional space, and locating/connecting center lines of the lane lines. The system builds a large connected network of lane elements and their connections as a lane element graph. The system also represents traffic signs based on camera images and detection and ranging sensor depth maps. These landmarks are used in building a high definition map that allows autonomous vehicles to safely navigate through their environments.

Abstract: This disclosure provides methods, devices and systems for improving wireless communications in power spectral density (PSD)-limited frequency bands. A wireless communication device, having a number (NTX) of transmit antennas, parses a physical layer (PHY) protocol data unit (PPDU) into a number (NSS) of spatial streams and modulates the NSS spatial streams on a number (M) of subcarriers.

The AP can support channel puncturing by selecting a particular spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.
