Publication number: 20240088963Abstract: Embodiments of this application provide a method and an apparatus for determining radio channel multipath information and a related device. A server obtains reference signal received powers of a plurality of downlink beams, and determines a path angle and path strength of a propagation path from an antenna in a power angular spectrum cell indicated by each power angular spectrum cell identity to a grid indicated by each grid identity, based on an association relationship between the reference signal received powers of the plurality of downlink beams and the following: a grid identity, a serving cell identity, and a power angular spectrum cell. The server can determine the radio channel multipath information based on the reference signal received powers of the plurality of downlink beams, instead of depending on map and engineering parameter information. This helps improve accuracy of the radio channel multipath information.Type: ApplicationFiled: November 19, 2023Publication date: March 14, 2024Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Xi Zheng, Yibin Kang, Qi Yan, Xin Chen

Publication number: 20230017001Abstract: This disclosure provide a vehicle control method. A first terminal device obtains first biometric information of a first user, generates a first key based on the first biometric information and identifier information of the first terminal device, and generates first verification information based on the first key. Further, the first terminal device sends the first verification information to an in-vehicle device. When successfully verifying the first verification information, the in-vehicle device controls a vehicle to start. If the first user loses the first terminal device, an unauthorized user that obtains the first terminal device cannot control the vehicle based on only the identifier information of the first terminal device. Because different users have different biometric information, a key generated by the first terminal device is different from the first key, and the in-vehicle device cannot control the vehicle to start. This improves vehicle security.Type: ApplicationFiled: September 16, 2022Publication date: January 19, 2023Inventors: Xin KANG, Haiguang WANG, Zhuo WEI, Zhongding LEI
