Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for beam training a reconfigurable intelligent surface (RIS) for sidelink communications between UEs. A base station may transmit an indication of a resource pool to a receiving UE and a transmitting UE for beam training a RIS.

The transmitting UE may transmit a sidelink reference signal using the identified resource. The receiving UE may receive the reference signal via the RIS according the pattern of beams and transmit a beam report to the transmitting UE. Beam training may be based on a capability of the RIS to use either a different beamformer or a different RIS configuration on different subchannels of the same resource pool.

Abstract: This document describes techniques for enabling de-aliased imaging for a synthetic aperture radar. Radar signals processed by a synthetic aperture radar (SAR) system may include false detections in the form of aliasing induced by grating lobes. The techniques described herein can reduce the adverse effects of grating lobes by obtaining an initial SAR image using a back-projection algorithm. Aliasing effects (e.g., false detections) in this initial image may be common due to the limitations of an SAR system moving at non-uniform speeds. A refined image is produced from the initial image by applying a de-aliasing filter to the initial image. The refined image may have reduced or eliminated false detections that attribute to aliasing effects, resulting in a better representation of the environment of the vehicle.

Abstract: Provided is a method of reconstructing multi-source long-time-series night light data and a system thereof, relating to the field of reconstructing ecological remote sensing data. Based on night light images of a first-generation satellite DMSP/OLS (Defense Meteorological Satellite Program/Operational Line-scan System) and a second-generation satellite NPP/VIIRS (National Polar-orbiting Partnership/Visible Infrared Imaging Radiometer Suite), a method of reconstructing a set of long-time-series night light data products is developed. Since satellite images that two generations of satellites have at the same time in a certain year use an inverse hyperbolic sine transform to fit NPP/VIIRS in 2013 into a data form of DMSP/OLS, and obtain an optimal fitting equation, thus producing a set of long-time-series data products from 1992 to 2021. The method can solve a fault problem between two generations of light data of DMSP/OLS and NPP/VIRS, and improve the accuracy of data reconstruction.

Abstract: There are proposed methods, devices, and computer program products for feature management. In the method, a first event associated with a first and a second object, and a second event associated with the first and second events are obtained, and a type of the first event is different from a type of the second event. A first feature of the first object is determined based on a first encoder, and a second feature of the second object is determined based on a second encoder. The first encoder is updated based on the first and second features and the first and second events. With these implementations, multiple events are used in determining the encoder for extracting the feature, and thus the encoder may have better performance in accuracy and increase performance of downstream tasks.
