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. In some implementations, the wireless communication device may transmit the PPDU using a number (N) of the transmit antennas, where NSS?N<NTX. In some other implementations, the wireless communication device may subdivide the M subcarriers into subcarrier groups and may transmit each subcarrier group using a respective subset of the NTX transmit antennas, where the number of transmit antennas used to transmit each subcarrier group is greater than or equal to the number of spatial streams modulated on the subcarriers in the group but less than NTX.

Abstract: This disclosure provides methods, components, devices and systems for protection for enhanced long range (ELR) transmissions. Aspects more specifically relate request to send (RTS) and clear to send (CTS) signaling exchanges for configuration of an ELR physical layer protocol data unit (PPDU) that protects ELR RTS/CTS frames from interference. For example, a first wireless device may indicate, via a first frame, a modified network allocation vector (NAV) timeout duration that accounts for a full duration of an ELR frame. In some examples, the modified NAV timeout duration may be calculated to account for a difference in data rate of the ELR frame relative to non-ELR frames. For example, the first wireless device may transmit a first frame prior to an ELR RTS/CTS frame, and the first frame may indicate, via a duration field, the modified NAV timeout duration that is calculated in accordance with the ELR RTS/CTS frame.

The first tone plan may define first fixed pilot tone locations, with pilot tones at the first fixed pilot tone locations being usable as IM pilot tones and/or usable as carrier frequency offset (CFO) pilot tones. The second tone plan may define second fixed pilot tone locations, with pilot tones at the second fixed pilot tone locations being exclusively usable as CFO pilot tones.

Abstract: This disclosure provides methods, components, devices and systems for interference mitigation (IM) mode signaling designs for a physical layer (PHY) protocol data unit (PPDU). Some aspects relate to IM mode signaling designs according to which two or more wireless communication devices may determine locations of IM pilot tones within a data portion of a PPDU. In some examples, the wireless communication device may input IM pilot tones prior to a spatial mapping stage in a transmit flow. In such examples, the wireless communication device may insert the IM pilot tones at fixed locations within the data portion of the PPDU and may support an interleaving stage such that the IM pilot tones are factored in. The interleaving stage may be associated with a tone mapping distance or an interleaver that is specific to scenarios in which the IM mode is set to an ON state.
