Summary

• What is new: The paper introduces significant enhancements to the TAP network timing method, achieving sub-microsecond synchronization which is far superior to current methods like NTP and PTP.
• Why this is important: The growing demand for precise time synchronization in mobile communication and industrial internet settings, where existing methods are inadequate.
• What the research proposes: Improving TAP with a detailed design for both base stations and terminals, incorporating hardware compensation and protocol software design to minimize errors and costs while ensuring 3GPP compatibility.
• Results: Developed a TAP 5G prototype system demonstrating 200ns level timing accuracy in field tests, with long-term observations showing an average accuracy of 1 nanosecond, vastly outperforming existing timing methods.

Technical Details

Technological frameworks used: Software Defined Radio for the base station, COTS baseband modules for the terminal
