Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/185526
Kind Code:
A1
Abstract:
Provided is a communication method (500). The communication method (500) comprises: a first device sending at least three reference signals (S501); a terminal device receiving the reference signals, and determining first information on the basis of a phase measurement result of each reference signal; and the terminal device sending the first information (S502), wherein the first information is used for indicating a direction angle, and the first device receives the first information. Since at least two of the at least three reference signals are sent or received by means of the same antenna, the terminal device or other devices may compensate, on the basis of the first information, for a phase error which is introduced due to frequency shift, such that angle measurement accuracy can be improved. Further provided are a communication apparatus, a chip and a computer-readable storage medium.
