Abstract

Abstract

In view of the challenges of 5G communication technology with high speed and multiple service scenarios, this paper proposes a new component-based Software Defined wireless access Network (SDN) architecture. Based on the architecture of Centralized Unit (CU), Distributed Unit (DU) and Active Antenna Unit(AAU) in 5G access network, further component-based evolution is carried out to form a new architecture composed the communication units of Centralized Control Unit (CCU), CU, DU, Radio Unit(RU), and AAU. This new architecture is not only conducive to the realization of wireless access network with slicing and virtualization, but also conducive to the adoption of distributed computing technology and hardware accelerating technology to break through the processing bottleneck of general-purpose processor, and reduce the forward transmission pressure between DU and AAU. In this paper, a prototype of component-based soft base station is developed and tested. The results show that the component-based scheme can not only provide high flexibility, but also improve the processing capacity of the general processor soft base station and reduce effectively the traffic of remote stations.
