Publication number: 20240329230Abstract: A terminal device first authenticates whether the terminal device has permission to sense a to-be-measured object. If the terminal device has sensing permission, the terminal device senses the to-be-measured object. If the terminal device has no sensing permission, the terminal device does not sense the to-be-measured object. In this way, privacy leakage of the to-be-measured object is prevented.Type: ApplicationFiled: June 13, 2024Publication date: October 3, 2024Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jia He, Xianfeng Du, Huang Huang

Publication number: 20230299934Abstract: A method and an apparatus for sensing and communication is provided. The method includes: a first device obtains a sensing parameter including a physical feature of a sensing target; configures a first frame based on the sensing parameter, and performs sensing on the first frame. The first frame includes M first time periods and N second time periods, both M and N are integers greater than or equal to 0, without being equal to 0 at the same time. The first device sends or receives a waveform of a communication signal during the first time period, and sends or receives a waveform of a sensing signal during the second time period. According to this application, spectral efficiency can be improved as sensing is performed without affecting communication thereby minimizing communication overheads, and sensing and communication occupy a same spectrum resource thereby meeting the requirements of sensing and communication.Type: ApplicationFiled: May 26, 2023Publication date: September 21, 2023Inventors: Jia He, Xianfeng Du

Publication number: 20230261781Abstract: Example communication methods and apparatus are described. One example method includes sending a first training signal by a first device to a second device on a reflection path. The first device sends a second training signal to the second device on the reflection path. The reflection path is a transmission path formed after the first training signal and the second training signal are reflected by a surrounding object. An interval between the first training signal and the second training signal is used to indicate to decode data.Type: ApplicationFiled: April 26, 2023Publication date: August 17, 2023Inventors: Jia HE, Xianfeng DU
