英文摘要	Novel centralized base station architectures integrating computation and communication functionalities have become important for the development of future mobile communication networks. Therefore, the development of dynamic high-speed interconnections between baseband units (BBUs) and remote radio heads (RRHs) is vital in centralized base station design. Herein, dynamic high-speed switches (HSSs) connecting BBUs and RRHs were designed for a centralized base station architecture. We analyzed the characteristics of actual traffic and introduced a switch traffic model suitable for the super base station architecture. Then, we proposed a data-priority-aware (DPA) scheduling algorithm based on the traffic model. Lastly, we developed the dynamic HSS model based on the OPNET platform and the prototype based on FPGA. Our results show that the DPA achieves close to 100% throughput with lower latency and provides better run-time complexity than iOCF and HE-iSLIP, thereby demonstrating that the proposed switch system can be adopted in centralized base station architectures.
