Title:
DISTANCE DETERMINATION METHOD AND APPARATUS, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/015556
Kind Code:
A1
Abstract:
A distance determination method and apparatus, a device and a storage medium, which relate to the field of mobile communications. The method comprises: acquiring a first distance, which is between a first communication device and a second communication device, wherein the first distance is determined on the basis of at least one first phase difference, each first phase difference being determined by means of a first carrier signal, which is received by the first communication device, and a local clock signal of the first communication device, and the first carrier signal being sent by the second communication device; determining a channel impulse response on the basis of an amplitude corresponding to at least one first carrier signal, and the first phase difference; and correcting the first distance on the basis of the channel impulse response, so as to obtain a second distance, and eliminating a path loss which is generated due to the refraction of a carrier signal by an obstacle and is included in the first distance, such that the corrected second distance is close to the actual distance between the two communication devices, thereby improving the accuracy of the determined distance between the first communication device and the second communication device.
