| Abstract: | This paper introduces the network clock synchronization scheme. For 5g network, the clock synchronization mismatch between 4G and 5g base stations will lead to the decline of 5g users" download rate and the failure of 4 / 5G interoperability. Based on the in-depth analysis of the phenomenon and causes, the paper proposes solutions such as providing 5g with base station synchronization signal through signal shunting, introducing new satellite receiving antenna and selecting 1588v2 clock scheme The plan and Prospect of the future promotion of the dual-mode transformation of the mobile base station Beidou / GPS time service system. This paper provides suggestions for the construction of 5g network clock synchronization. |
