COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/017098
Kind Code:
A1
Abstract:
Provided in the present application are a communication method, a communication apparatus, and a computer-readable storage medium and a computer program product in the field of communications. The method comprises: a first communication device acquiring the difference between the moment at which a second communication device sends a reference signal and the moment at which the second communication device receives a reference signal from a third communication device; acquiring the difference between the moment at which the third communication device sends the reference signal and the moment at which the second communication device receives the reference signal from the second communication device; acquiring the difference between the moment at which a fourth communication device receives the reference signal from the second communication device and the moment at which the fourth communication device receives the reference signal from the third communication device; and determining, on the basis of the time differences, a time difference of flight between a signal time of flight of the second communication device and the fourth communication device and a signal time of flight of the third communication device and the fourth communication device. Since a time difference of flight is determined on the basis of time differences and is not affected by the clock synchronization between communication devices, the precision of the time difference of flight can be improved.
