摘      要：Novel centralized base station architectures integrating computation and communication functionalities have become important for the development of future mobile communication ***,the development of dynamic high-speed interconnections between baseband units(BBUs)and remote radio heads(RRHs)is vital in centralized base station ***,dynamic high-speed switches(HSSs)connecting BBUs and RRHs were designed for a centralized base station *** analyzed the characteristics of actual traffic and introduced a switch traffic model suitable for the super base station ***,we proposed a data-priority-aware(DPA)scheduling algorithm based on the traffic ***,we developed the dynamic HSS model based on the OPNET platform and the prototype based on *** 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.
