Publication number: 20240129759Abstract: Methods, systems, and devices for wireless communications are described. In some systems, devices use machine learning (ML) models to support wireless communications. For example, a user equipment (UE) may download ML model information from a network to determine an ML model. The network may additionally configure a status reporting procedure, a fallback procedure, or both for the ML model. In some examples, based on a configuration, the UE may transmit a status report to a base station according to a reporting periodicity, a UE-based trigger, a network-based trigger, or some combination thereof. Additionally or alternatively, the UE may determine to fallback from operating using the ML model to operating in a second mode based on a fallback trigger. In some examples, to restore operating using a downloaded ML model, the UE may download an updated ML model or receive iterative updates to a previously downloaded ML model.Type: ApplicationFiled: April 22, 2021Publication date: April 18, 2024Inventors: Yuwei Ren, Ruiming Zheng, Xipeng Zhu, Chenxi Hao, Shankar Krishnan, Yu Zhang, Huilin Xu, Hao Xu, Yin Huang, Taesang Yoo

Publication number: 20230231377Abstract: The present disclosure relates to a method for protecting DC line impedance phase based on protection and control coordination, and an application scenario of the method for protecting is a three-terminal flexible DC transmission network. The method uses high controllability of a converter after a fault, injects a characteristic signal at a characteristic frequency, and calculates a phase angle of input impedance to determine a fault interval, which effectively improves protection performance, turns passive to active, and is not affected by nonlinearity of the converter. At the same time, compared with a full-bridge MMC, using a half-bridge MMC does not need to perform fault ride-through first when identifying a fault, and does not need to add additional equipment, it creates fault features and can reliably identify an fault interval; improves protection quickness and at the same time also has better economic benefits.Type: ApplicationFiled: July 1, 2022Publication date: July 20, 2023Applicant: Beijing Jiaotong UniversityInventors: Meng LI, Jinghan HE, Keao CHEN, Dahai ZHANG, Pinghao NI, Yin XU, Xiaojun WANG, Guomin LUO, Xiangyu WU, Fang ZHANG

Patent number: 11380594Abstract: Machine learning techniques are used to predict values of fixed parameters when given reference values of critical parameters. For example, a neural network can be trained based on one or more critical parameters and a low-dimensional real-valued vector associated with a spectrum, such as a spectroscopic ellipsometry spectrum or a specular reflectance spectrum. Another neural network can map the low-dimensional real-valued vector. When using two neural networks, one neural network can be trained to map the spectra to the low-dimensional real-valued vector. Another neural network can be trained to predict the fixed parameter based on the critical parameters and the low-dimensional real-valued vector from the other neural network.Type: GrantFiled: February 23, 2018Date of Patent: July 5, 2022Assignee: KLA-TENCOR CORPORATIONInventors: Tianrong Zhan, Yin Xu, Liequan Lee
