This paper focuses on the clock synchronization in the integration of IEEE 802.1 Time Sensitive Networking (TSN) and fifth-generation (5G) mobile technology in industrial communication networks. Clock synchronization is key function for deterministic communication by providing precise and unified time between different systems. Current researches only considers the a simplified case of a single 5G bridge. However, multiple bridges increase cumulative synchronization error that degrade the accuracy of clock synchronization. To address this issue, the article proposes a clock synchronization scheme with timestamp compensation and carrier spacing optimization for synchronization accuracy. The proposed network architecture suggests a heterogeneous network convergence scheme for 5G+TSN in this particular scenario. This scheme incorporates carrier spacing optimization, which integrates synchronization accuracy and bandwidth utilization, and timestamp compensation to effectively reduce cumulative error in scenarios involving multiple bridges. The simulations demonstrated that our scheme provides accurate clock synchronization for multi-field manufacturing systems scenarios to achieve the cooperative work through the 5G network.
