Abstract: An example device for processing image data includes a processing unit configured to determine a set of criteria representing keypoints of interest for processed image data; extract a plurality of keypoints from the image; determine which of the plurality of keypoints match the set of criteria representing the keypoints of interest to determine a matched set of keypoints; and output data representative of the matched set of keypoints.

Abstract: Methods, systems, and devices for wireless communications are described in which multiuser superposition transmission (MUST) is used to provide multiple concurrent sidelink transmissions using a same set of time and frequency resources. A transmitting user equipment (UE) may provide an indication of concurrent MUST transmissions in sidelink control information (SCI), and a receiving UE may decode one or both of a MUST base layer communication and a MUST enhancement layer communication. The base layer communication may include broadcast or groupcast transmissions to multiple UEs, and the enhancement layer communication may include a unicast transmission between the transmitting UE and a single receiving UE. The indication of concurrent transmissions may be provided in a first stage SCI, and parameters for decoding the base layer and enhancement layer transmissions may be provided in one or multiple second stage SCI transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to transmit feedback information via a configurable quantity of interlaced resource blocks (IRBs) in one or more interlaces of a sidelink feedback channel. For example, the UE may transmit feedback via multiple IRBs of an interlace. The UE may determine which IRBs to use in accordance with a configuration, which may indicate a quantity of IRBs, a distribution of the IRBs, a pattern of the IRBs, or any combination thereof. Additionally, or alternatively, the UE may determine to transmit feedback via multiple IRBs of an interlace that is different from a common interlace.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may support superimposed NR and LTE transmissions using an antenna port, in conjunction with an LTE-aware, NR slot structure (e.g., an NR V2X slot structure). In some aspects, the slot structure may protect portions of the LTE signal from interference, increasing LTE decoder robustness to interference which may provide opportunities for increasing the NR signal power. The UE may transmit a superimposed transmission of an LTE signal and an NR signal from a same antenna port in a same radio frequency resource. In some aspects, the slot structure may be modified so that the UE does not transmit when LTE reference signals are transmitted, so as to avoid interference with the LTE reference signals. A receiving UE may use the LTE reference signals to demodulate the LTE signal and the NR signal from the common time and frequency resources.
