The clock synchronization is considered as a key technology in the time-sensitive networking (TSN) of 5G fronthaul. This paper proposes a clock synchronization enhancement method to optimize the link delays, in order to improve synchronization accuracy. First, all the synchronization dates are filtered twice to get the good calculation results in the processor, and then FPGA adjust the timer on the slave side to complete clock synchronization. This method is implemented by Xilinx Zynq UltraScale+ MPSoC (multiprocessor system-on-chip), using FPGA+ARM software and hardware co-design platform. The master and slave output Pulse Per-Second signals (PPS). The synchronization accuracy was evaluated by measuring the time offset between PPS signals. Contraposing the TSN, this paper compares the performance of the proposed scheme with some previous methods to show the efficacy of the proposed work. The results show that the slave clock of proposed method is synchronized with the master clock, leading to better robustness and significant improvement in accuracy, with time offset within the range of 40 nanoseconds. This method can be applied to the time synchronization of the 5G open fronthaul network and meets some special service needs in 5G communication.

W pracy zestawiono architekturę systemu 5G oraz przemysłowego IoT opartego na TSN. W celu eliminacji okablowania zaproponowano koncepcję zespolenia prywatnej sieci 5G/6G oraz systemu przemysłowego IoT. W prywatnej części sieci zaproponowano wprowadzenie bezprzewodowego interfejsu Li-Fi oraz sieci światłowodowej zbudowanej na bazie światłowodów wielordzeniowych. W celu uniwersalizacji systemu, w domenie sygnałów radiowych wprowadzono architekturę C-RAN/SDR.

In the paper the architecture of the 5G system and the industrial IoT based on TSN were presented. In order to eliminate cabling, the concept of convergence a private 5G/6G network and the industrial IoT was proposed. In the private part of the network, it was proposed to introduce a wireless Li-Fi interface and a fiber-optic network built on the basis of multi-core optical fibers. In order to universalize the system, the C-RAN/SDR architecture was introduced in the domain of radio signals.
