Outline of Final Research Achievements

This project has proposed a system architecture for basestation cooperated heterogeneous networks as a baseline for 5G cellular systems. This project has developed several Radio Resource Management (RRM) algorithm needed to operate the basestation cooperated heterogeneous networks efficiently such as user association, dynamic ON/OFF control, and dynamic clustering. Performance improvement has been proven via system level simulations to achieve 1000 times better system rate than the conventional 4G cellular networks. This project has also developed prototype hardware of basestation cooperated C-RAN with new interface between LTE and small-cell basestation and control / data-plane splitting. Finally, this project has contributed to 3GPP standardization about the proposed interface and control protocols.
