Meeting with the evolution requirements from 3G to 4G system, FuTURE project and FuTURE 4G TDD system are introduced in detail, including the features, the key technologies related with the cellular architecture, physical layer and the implementation of trial system. It has been proved by the field tests that the FuTURE TDD system that can achieve the peak data rate of 122Mbps, where many enhanced technologies comparing with TD-SCDMA are adopted, including the Generalized Distributed Network Architecture, Soft Fractional Frequency Reuse and Fast Cell Group Selection. Moreover, some technologies proposed in the research and development of FuTURE TDD system have been accepted by 3GPP and become the candidate standards of the Enhanced 3G systems. At last, Gbps TDD system is now under researching and developing in China aiming with ITU IMT-Advanced (4G) system.
