Powering saving is one of the key technologies in mobile terminal design.This paper summarizes the overall structure of TD-SCDMA terminal
and then the power consumption characteristics of TD-SCDMA terminal are analyzed and finally using dynamic management technology experiment on the power saving techniques based on the DBB and RF.It effectively extends the working time of TD-SCDMA terminal.This has both significant technical and practical bearing on the development of the TD-SCDMA industry.
