The development of wireless communications cannot be separated from the key technology of clock synchronization. Compared to the traditional wireless communication methods, stricter requirements for clock synchronization of systems are put forward in 5G communication technology. The Synchronous Ethernet (SyncE) technology and IEEE 1588V2 Precision Clock Synchronization Protocol (PTP) are introduced, and their necessity for the development of 5G technology is clarified. Based on the above technologies, a clock synchronization system for integrated 5G base stations is designed. The technical methods, hardware design, software design, and system implementation are described in detail. Finally, an experimental environment is established, in which the feasibility is verified in terms of clock synchronization accuracy and stability.
