rollout CONTENTS DTmobile Overview； TDHSDPA Complete Solutions and Products； TDHSDPA in China DTmobile TDHSDPA Milestones。 Why to Choose TDHSDPA? • Optimally enhance the performance of TDSCDMA system • Maximally guarantee backward patibility and the scalability of system • Provide flexibility to guarantee the most efficient use of resources • ONLY need software upgrade to smoothly migrate from TDSCDMA R4 to TDHSDPA • The peak rate of TDHSDPA may reach N* (N=number of carriers) when UL/DL timeslot ratio is 1:5. The peak rate , already higher than the of WCDMAbased HSDPA, can be reached on 10MHz bandwidth. • As to WCDMA based HSDPA, if on 10 MHz, requires continuous 5MHz timeslots on UL and DL respectively, while TDHSDPA may take use of 6 separated carriers ( each). Considering the limited frequency resource, this is an obvious advantage of TDSCDMA over WCDMA. • Regarding the deployment of both R4 and HSDPA works, the narrow bandwidth based TDHSDPA has many advantages on the efficiency of resource allocation and the simplicity and flexibility of configuration over WCDMA HSDPA. What is HSUPA? – Key technologies adopted for enhanced UL performance include: • Adaptiv。
