| Abstract: | TD-SCDMA introduces the high-speed uplink packet access (HSUPA) in Release 7 to satisfy the demand of service for high-speed data service in the mobile network. This paper briefly introduces the principle of TD-HSUPA, elaborates the essential technology of TD-HSUPA and its implementation, compares the difference of the HSUPA technology application in TD-SCDMA system with that in WCDMA system. It is significant to the next step of TD-SCDMA evaluation technology (HSPA+,LET). |
