TD-SCDMA Milestones In China
8 Year Development Path (19982006)
Market Application Phase
Products network tests were completed in H1 05,
and all will be ready for market in 2006. The
research of technology migration path has already
started.
Kicked off with the establishment of DTmobile on
Feb. 2002. The process lasted until the end of
2004.
Product Development Phase
Technology Testification Phase
Two phases of MTNet tests, including indoor and
field tests, were completed from 1999 to 2002.
Standard Development Phase
TD-SCDMA standard was proposed in July 1998 and
accepted by ITU and 3GPP respectively by the end
of 2001.
China Academy of Telecommunications and
Technology (CATT) submitted TD-SCDMA proposal to
the ITU on behalf of the Chinese government in
June 1998. DTmobile, as the sub company of CATT,
is involved in TD-SCDMA RD, industrialization
and commercialization in China and throughout the
world.

Why to Choose TD-HSDPA?

• Optimally enhance the performance of TD-SCDMA
  system
• Maximally guarantee backward compatibility and
  the scalability of system
• Provide flexibility to guarantee the most
  efficient use of resources
• ONLY need software upgrade to smoothly migrate
  from TD-SCDMA R4 to TD-HSDPA

• The peak rate of TD-HSDPA may reach N 2.8Mbps
  (Nnumber of carriers) when UL/DL timeslot ratio
  is 15. The peak rate 16.8Mbps, already higher
  than the 14.4Mbps of WCDMA-based 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 TD-HSDPA may take use of 6
  separated carriers (1.28MHz each). Considering
  the limited frequency resource, this is an
  obvious advantage of TD-SCDMA over WCDMA.
• Regarding the deployment of both R4 and HSDPA
  networks, the narrow bandwidth based TD-HSDPA has
  many advantages on the efficiency of resource
  allocation and the simplicity and flexibility of
  configuration over WCDMA HSDPA.

What is HSUPA?

• The targets are,
• to greatly enhance UL transmission bit rate
• to better support interactive, background and
  streaming services
• to reduce time latency on interaction

• Key technologies adopted for enhanced UL
  performance include
• Adaptive modulation and coding (AMC),
• Hybrid ARQ,
• NB control and scheduling,
• Fast allocation of dedicated/shared resource, and
• The relevant support mechanism of physical-layer
  and high-layer signaling

TD-SCDMA HSDPA
DTmobile Support Boosts TD-HSDPA
TD-SCDMA HSDPA
- Theoretical peak rate of 2.8 Mbps on 1.6MHz
bandwidth (DL 5 timeslots)
Singe carrier HSDPA
- TD-SCDMA multi-carrier technology is featured
by the flexible configuration of resources, the
backward compatibility with the current TD-SCDMA
network, and the solution to effectively meet the
requirement on large-capacity and high-speed data
transmission.
Muti-carrier HSDPA

Two proposals submitted by DTmobile to 3GPP for
evaluation

• TD-SCDMA multi-carrier solution, as a short-term
  goal, emphasizes smooth migration and provides
  enhanced TD-SCDMA system performance.
• TDD-OFDM solution is a long term TD-SCDMA
  evolution plan which aims at a total performance
  enhancement.
