With the trend of surging mobile traffic and limited spectrum resource,traditional radio access network is facing lots of challenges,which are system capacity limited by interference,inflexibility of multi-standard and dynamic workload,high CAPEXOPEX.In order to handle these challenges,the future architecture of radio access network will be developed in a cooperative style at air interface.In this architecture,each base station cooperatively optimizes the radio resource allocation and improves the spectral efficiency.In addition,the base-band pool technology can reduce the CAPEXOPEX of RAN and improve the efficiency of resource utilization greatly through utilizing baseband virtualization technology.
