MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647091593 A) filed by Qualcomm Incorporated on July 28, 2026, for Multi-Port Nonlinear Frequency-Modulated (nlfm) Radio Frequency (rf) Sensing.
Inventors include Liu, Kangqi; Duan, Weimin; and Zhang, Danlu.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: In some implementations, configuring node of a wireless network may receive multi-port non-linear frequency-modulated (NLFM) capability information indicative of an ability of a sensing node to generate NLFM signals for performing a radio frequency (RF) sensing function. The configuring node may determine, based on the NLFM capability information, an NLFM configuration for generating a set of NLFM signals comprising two or more NLFM signals. Each of the two or more NLFM signals may correspond to a respective antenna port of the sensing node. The NLFM configuration may include a type of NLFM signal to use for the set of NLFM signals, and one or more parameters for generating the set of NLFM signals. The configuring node may send the NLFM configuration to the sensing node to generate the set of NLFM signals to perform the RF sensing function.
