SENSING METHOD, DEVICE, AND SYSTEM

WIPO Patent Application WO/2024/000525

A1

The present application provides a sensing method, device, and system, applied to the technical field of communications. The sensing method provided by the present application comprises: a second communication device receives waveform information of a first signal and an echo signal of the first signal; the second communication device determines a first cross-correlation function according to the first signal and the echo signal of the first signal; the second communication device determines, according to the first cross-correlation function, that a first ambiguity function needs to be suppressed; the second communication device sends first indication information to a first communication device, wherein the first indication information is used for determining a second ambiguity function, and the second ambiguity function has local amplitude suppression relative to the first ambiguity function; and the second communication device receives an echo signal of a second signal. On the basis of the method, if a receiver determines that an ambiguity function of a sensing signal needs to be suppressed, the receiver sends indication information to a transmitter, so that the transmitter can determine a suppressed ambiguity function according to the indication information and correspondingly adjust the sensing signal, thereby improving the sensing performance of the sensing signal.
