In this split architecture, one CU is able to control several DUs, which enables the function of base-band central control and remote service for users. In this paper, the general aspects of CU-DU split architecture are introduced, including the split method, interface functions （control plane functions and user plane functions）, mobility scenarios and other CU-DU related issues. The simulations show the performance of Options 2 and 3 for CU-DU split.展开更多
