Optimal Function Split via Joint Optimization of Power Consumption and Bandwidth in V-RAN

This paper studies Dual site processing in Virtualized Radio Access Network (V-RAN) and it recommends the amount of processing in the dual sites for the functional splits which are proposed by ETSI. This leads to ease of management and flexibility of the operation and increases processing and power efficiencies. To recommend the amount of processing in both sites, the power consumption at several percentages of functional splits is identified to compromise the tradeoff between the midhaul capacity and power consumption. Furthermore, Joint optimization of power consumption and midhaul capacity is performed to validate and recommend the optimal split function.
