MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202647041708 A) filed by Qualcomm Incorporated, San Diego, on April 1, for 'frequency domain (fd)-scrambled frequency modulated continuous wave (fmcw) signaling.'
Inventor(s) include Liu, Kangqi; Duan, Weimin; and Jiang, Jing.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "Methods, systems, and devices for wireless communications are described. The described techniques provide for a device to distinguish between signals transmitted using frequency modulated continuous wave (FMCW) waveforms. A first wireless device may apply a frequency-domain (FD) scrambling sequence to a reference signal for transmission, and a second wireless device may receive at least a portion of the signal and de-scramble the signal using the FD scrambling sequence. In some examples, the first wireless device may transmit configuration signaling indicating the FD scrambling sequence corresponding to the first wireless device. Additionally, or alternatively, the first wireless device may transmit an indication for the second wireless device to determine the FD scrambling sequence based on identifier (ID) information (e.g., an ID associated with the first wireless device). In some examples, the first wireless device, the second wireless device, or both may use analog or digital transceivers."
The patent application was internationally filed on Oct. 14, 2024, under International application No.PCT/US2024/051286.
