Communication method and communication apparatus

A communication method, wherein the method comprises:

• receiving, by a third communication apparatus, first phase information from a first communication apparatus, wherein the first phase information comprises at least one first phase, or the first phase information is determined based on the at least one first phase, and the at least one first phase is obtained by the first communication apparatus by measuring at least one first positioning reference signal sent by at least one second communication apparatus;
• receiving, by the third communication apparatus, second phase information from the first communication apparatus, wherein the second phase information comprises at least one second phase, or the second phase information is determined based on the at least one second phase, and the at least one second phase is obtained by the first communication apparatus by measuring at least one second positioning reference signal sent by the at least one second communication apparatus;
• receiving, by the third communication apparatus, first information from the first communication apparatus, wherein the first information is information about phase correlation between the first phase information and the second phase information;
• and
• positioning, by the third communication apparatus, the first communication apparatus or the at least one second communication apparatus based on the first phase information, the second phase information, and the first information.

A first communication apparatus, comprising:

• at least one processor coupled to at least one memory storing instructions and configured to execute the instructions to cause the apparatus to perform:
• measuring at least one first positioning reference signal from at least one second communication apparatus, to obtain at least one first phase;
• sending first phase information to a third communication apparatus, wherein the first phase information comprises the at least one first phase, or the first phase information is determined based on the at least one first phase;
• measuring at least one second positioning reference signal from the at least one second communication apparatus, to obtain at least one second phase;
• sending second phase information to the third communication apparatus, wherein the second phase information comprises the at least one second phase, or the second phase information is determined based on the at least one second phase;
• and
• sending first information to the third communication apparatus, wherein the first information is information about phase correlation between the first phase information and the second phase information.
