Communication method and communication apparatus

A communication method, comprising:

• sending a first downlink frame to a first communication apparatus;
• receiving a first uplink frame from the first communication apparatus;
• receiving first information from the first communication apparatus, wherein the first information indicates a first time difference between a receiving time for receiving an ith first downlink subframe in the first downlink frame and a sending time for sending a kth first uplink subframe in the first uplink frame;
• and
• sending the first information to a positioning server, wherein the first information is used by the positioning server to verify a location of a terminal device.

An apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing program instructions for execution by the at least one processor to cause the apparatus to:
• receive a first downlink frame from a second communication apparatus;
• send a first uplink frame to the second communication apparatus;
• and
• send first information to a positioning server, wherein the first information indicates a first time difference between a receiving time for receiving an ith first downlink subframe in the first downlink frame and a sending time for sending a kth first uplink subframe in the first uplink frame.
