The vision on future TD-SCDMA

Abstract

As the increasing demand for mobile data service, 2Mbps peak data rate of TD-SCDMA will not fulfill the user’s need any more in several years. While the new B3G system to provide high data rate service is still not available until 2010, the current TD-SCDMA must be enhanced to fulfill the requirement of the new service. As one 3G standard accepted by ITU and 3GPP, TD-SCDMA should also be enhanced and improved as WCDMA and CDMA2000. In this paper, the future vision on the evolution and enhancement of TD-SCDMA is given out. According to our research, the smooth evolution from TD-SCDMA to B3G TDD can be summarized as five phases: TSM, LCR, HDR, B3G TDD and after 4G; while the research and development on TD-SCDMA enhancement can be done from the aspects of Generalized Distributed Antenna Arrays (GDAA), Dynamical Radio Resource Management, MIMO, AMC, etc. Finally, a High Data Rate proposal for TDSCDMA is presented as a reference for future research on this topic, and the peak data rate is 3.96Mbps.
