The document discusses the technology behind HSDPA (High Speed Downlink Packet Access), which enhances the downlink speed of WCDMA networks. It describes the drivers for adopting HSDPA, including increasing competition from other technologies, and explains the key technologies that enable HSDPA's higher speeds, such as adaptive modulation and coding, hybrid ARQ, and fast scheduling. Finally, it discusses the commercial deployment of HSDPA terminals and networks beginning in 2005.

The driver to HSDPA
High Speed Downlink Packet Access
 HSDPA is a new technology to enhance WCDMA PS data service
 HSDPA gives subscribers new experience of more higher speed data
service with shorter time delay
 HSDPA brings more bandwidth and more online subscribers
 It is necessary and feasible to introduce HSDPA to WCDMA network
 With consideration of network planning and deployment cost, HSDPA
should be applied at the beginning, or at least the Node B should
hardware ready for HSDPA
 HSDPA brings new requirement of transmission and network planning.

 Adaptive Modulation and
Coding (AMC), Node B can
adjust modulation (QPSK,
16QAM) and coding rate (1/3,
3/4, etc) in time according to the
feedback channel state from UE.
So data transferring can follow
the step of channel state
changing in time, it is a good

 HSDPA makes the balance between the coverage and the throughput, increase the coverage
decrease the throughput.
 HSDPA provides about 200kbps in the edge of cell, Less than the R99/R4 DCH.
 Recommend to combine the HSDPA and R99/R4 DCH together, at the edge of cell UE can
“handover” into DCH. With this combination, you can take the most advantage from R99/R4 and

Network analysis for HSDPA and R99/R4
 After the 3G network construction, the basic demand of WCDMA network
should adopt HSDPA function, with soft smooth upgrade ability
 HSDPA is not constructed as a individual network, HSDPA is a enhanced
technology of WCDMA (throughput, users)
 Network construction and plan for R99 and HSDPA based on the “one-shot
planning, multi-stage deployment”
 HSDPA and R99 share the same network, Node B supports HSDPA
function
 At dense traffic area (capacity is restricted), HSDPA can share the
same site of R99 and achieve the same coverage of it.
 Capacity and coverage is a balance relationship, increase the network
performance to the maximum by making a balance between them.

42. HSDPA Solution
HSDPA transmission solution
HSDPA requires more transmission resource, because of the changing
of capacity of Node B and traffic mode
For capacity For traffic mode
 R99 cell peak data rate:  The PS traffic mode will change greatly,
7×384Kbps=2.688Mbps more PS traffic will rush into HSDPA
system
 HSDPA cell peak data rate:
15×960Kbps×3/4 = 10.8 Mbps
 Peak throughput of HSDPA cell is
4 times as that of R99 cell
 Peak traffic of 3CS HSDPA Node B:
10.8×3×1.3×80% ＝ 32M
 Peak throughput of HSDPA cell is 4 times as that of R99 cell, and
mean throughput of HSDPA cell is 2 times as that of R99 cell
 Consider both capacity and traffic mode, transmission resource of Iub
at beginning should be reserved 4 times as before or at least 2 times

ZTE Node B hardware support HSDPA
 HSDPA functions have already been embedded into ZTE serialized Node B
hardware. The base-band processing chip supports 16QAM modulation. Only
software update is needed for Node B to support HSDPA.
 Powerful base-band processing ability. For the case of updating the R99 cell into
R99/HSDPA, no more base-band processing board is needed for Node B.
 As for RNC and CN, the introduction of HSDPA will only increase the data traffic
which means only additional interface hardware resource are needed.
ZTE Node B is designed based on the most advanced
HSDPA technology in the world. It is absolutely ensured
that to upgrade from R99 to HSDPA, no board is
required to be changed! The base-band processing
board also possesses a unique feature that is it
supports the networking of HSDPA and R99 with either
the same carrier or not! The most advanced base band
processing in the world!

49. HSDPA Solution
ZTE HSDPA solution conclusion
 ZTE serialized Node B is already hardware ready
for downlink 14.4M, only software upgrade is All the Node Bs support HSDPA
needed
 ZTE RNC and CN, unified platform, 80G switching
capability, high integration, high capacity, smooth
evolution, to ensure the deployment of HSDPA
 HSDPA can share carrier with R99/R4, or use a
exclusive carrier
 Support handover between HSDPA, R99/R4 and
2G
 Support simultaneous service of HSDPA and voice
(or video telephony)
 Support at least 64 users per cell
 HSDPA can share base band board with R99/R4
