Abstract: This disclosure provides wireless communication methods, components, devices and systems for applying spectral masks and spectral flatness parameters in conjunction with transmission of millimeter wave (mmWave) signals in wireless communication networks. In some examples, in conjunction with transmission of an mmWave signal, a wireless communication device can apply a derivative spectral mask featuring transitional offset ranges that correspond to transitional frequency offset ranges of a spectral mask for a nominal carrier signal, scaled according to a ratio between a bandwidth of the mmWave signal and a bandwidth of the nominal carrier signal. In some examples, the derivative spectral mask can feature an in-band frequency offset range that is wider than a scaled width of an in-band frequency offset range of the spectral mask for the nominal carrier signal.

Abstract: In various examples, three-dimensional (3D) object or feature detection and localization for autonomous and semi-autonomous systems and applications is described herein. Systems and methods are disclosed that use different types of sensors, such as an image sensor and a LIDAR sensor, to determine information associated with objects, such as traffic objects (e.g., traffic signs, traffic signals, traffic markings, etc.). To determine the information for an object, image data is processed to determine a bounding shape associated with the object. The bounding shape is then used to determine a 3D shape, such as a frustum, corresponding to the object. Additionally, points data generated using the LIDAR sensor, such as an occupancy map and/or a point cloud, is processed to identify a portion of the points associated with (e.g., located within) the 3D shape. This portion of the points may then be used to determine the information associated with the object.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. An example apparatus selects a first resource unit (RU) of a plurality of RUs for transmitting a physical (PHY) layer convergence protocol (PLCP) protocol data unit (PPDU) over a wireless medium. The first RU may include a set of contiguous tones occupying a first frequency bandwidth. The plurality of RUs may collectively span a second frequency bandwidth greater than the first frequency bandwidth. The apparatus maps the set of contiguous tones of the first RU to a set of non-contiguous tones distributed across the second frequency bandwidth using a tone mapping vector and a tone mapping offset associated with the first RU. The apparatus transmits the PPDU over the set of non-contiguous tones distributed across the second frequency bandwidth.

Abstract: This disclosure provides methods, devices and systems for link adaptation in wireless communications. Some implementations more specifically relate to transmitter-based modulation and coding scheme (MCS) selection. A transmitting device transmits a test packet, over a wireless channel, to a receiving device. The receiving device generates one or more signal-to-interference-plus-noise ratio (SINR) estimates for the wireless channel based on the received sounding packet. In some aspects, each SINR estimate may be associated with a particular modulation order. In some other aspects, each SINR estimate may be generated based on a transmitter configuration or a receiver type to be used for subsequent communications between the transmitting device and the receiving device. The receiving device transmits feedback, including the SINR estimates, to the transmitting device.

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.
