Abstract: This disclosure provides methods, components, devices and systems for physical layer (PHY) latency reduction. Some aspects more specifically relate to PHY protocol data unit (PPDU) designs that support inserting low-latency traffic into a transmission opportunity (TXOP) occupied by non-low-latency traffic.

The AP may obtain, from an application layer, a low-latency PPDU (LL-PPDU) subframe and may insert the LL-PPDU subframe in place of at least one of the one or more A-PPDU subframes. The AP may output the LL-PPDU subframe during the TXOP. A wireless station (STA) receiving the A-PPDU header and the one or more A-PPDU subframes may detect the presence of the LL-PPDU subframe and may receive and decode the LL-PPDU subframe.

Some implementations more specifically relate to BSS discovery and association techniques that support wireless communications on carrier frequencies above 7 GHz. In some aspects, an access point (AP) may communicate using beamforming on a wireless communication link operating at a carrier frequency above 7 GHz (the “directional link”) while offloading the BSS discovery and association procedures needed to support such communications onto a wireless communication link operating at a carrier frequency below 7 GHz (the “anchor link”). In some implementations, the AP may perform a beamforming training operation with a STA over the directional link upon associating with the STA over the anchor link. In such implementations, the AP may communicate with the STA over the directional link using a beam derived from the beamforming training operation.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless station (STA) (for example, an access point (AP) or a non-AP STA) may transmit a message to one or more STAs in a multiple basic service set (BSS) system that indicates one or more distributed resource units (RUs) for the STAs to use for communications, in which each distributed RU includes a respective set of tones interspersed within a channel bandwidth such that tones of different BSSs are interleaved. For example, a coordinating STA may indicate respective distributed RUs assigned to each BSS, and may communicate with the STAs using tones of the distributed RUs for the BSS supported by the coordinating STA. In some other examples, a STA may indicate occupied distributed RUs and a permission condition to another STA, such that the other STA may use unoccupied distributed RUs for communications in accordance with the permission condition.

Abstract: Embodiments relate to methods for efficiently encoding sensor data captured by an autonomous vehicle and building a high definition map using the encoded sensor data. The sensor data can be LiDAR data which is expressed as multiple image representations. Image representations that include important LiDAR data undergo a lossless compression while image representations that include LiDAR data that is more error-tolerant undergo a lossy compression. Therefore, the compressed sensor data can be transmitted to an online system for building a high definition map. When building a high definition map, entities, such as road signs and road lines, are constructed such that when encoded and compressed, the high definition map consumes less storage space. The positions of entities are expressed in relation to a reference centerline in the high definition map. Therefore, each position of an entity can be expressed in fewer numerical digits in comparison to conventional methods.

Multi-AP coordination may refer to coordinated beamforming (CoBF), joint transmission (JT), or coordinated orthogonal frequency division multiple access (C-OFDMA). Additionally, or alternatively, some implementations more specifically relate to preamble designs that accommodate signal fields of different cases.
