Method for processing round trip delay, related apparatus, and readable storage medium

A second communications apparatus, comprising a processor and a memory which is coupled to the processor;

• wherein the memory is configured to store a computer program;
• and
• the processor is configured to execute the computer program stored in the memory, the computer program when executed by the processor, cause the apparatus to:
• receive a delay quantization parameter of a common round trip delay (RTD) rather than the RTD itself, from a first communication apparatus, wherein the delay quantization parameter comprises a first quantization parameter, and the first quantization parameter is a delay index, and the delay index indicates a height-related delay at a height of the first communication apparatus corresponding to the delay index;
• and
• obtain the common RTD based on a correspondence between the delay index and a height-related delay stored in the second communication apparatus.
