The driver to HSDPA
 HSDPA is a new technology to enhance WCDMA PS data service
 HSDPA gives subscribers new experience of more higher speed data
service with more 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
technology for link self-adaptive
 For long time delay packet data,
AMC can improve system
capacity without add
interference to neighbor cells

HSDPA terminal mode
HSDPA network both supports UE with HSDPA function
or without HSDPA function.
To make full use of the network, we recommend to use
dual mode (GPRS/HSDPA) or multi mode
(GSM/GPRS/HSDPA) terminals.
If you want to access into HSDPA network, at least
you should prepare a normal WCDMA UE as in R99.
In the future, WCDMA terminal will use HSUPA to
improve the uplink speed.

Max path loss
HSDPA can achieve the same coverage as R99/R4 under same data rate

Combination of HSDPA and R99/R4
 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
HSDPA.
 Refer to: radius of CDMA 2000 1x EV-DO cell is 907.5m.

Handover between HSDPA and R99/R4
 Support various handover method of HSDPA
 DCH to HS-DSCH channel handover
 HS-DSCH to DCH channel handover
 HS-DSCH to FACH channel handover
 FACH to HS-DSCH channel handover
 HS-DSCH to 2G “handover”
 With handover among HSDPA, R99/R4 and 2G network, achieve the HSDPA seamless coverage
handover policy motivation description
Handover based
on traffic
The traffic load for HSDPA
and R99/R4 has large
difference. Then we trigger
the handover
trigger handover while the traffic load of HSDPA cell is
too heavy and the load of R99/R4 cell is lower, or the
traffic load of different HSDPA cells are not in balance
Handover based
on service
According to the service type
and data rate to choose
HSDPA or R99/R4 network
Low speed data service can be handled with FACH,
Streaming service can be handled with DCH; the rest
high speed PS data service or non-real time data
service should be assigned to HSDPA
Handover between HSDPA, R99/R4 and DCH/FACH channels，can
guarantee the service stability of HSDPA

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.
 Have to take into consideration
 How to solve various radio environment coverage and capacity？
 How to ease the transmission resource after deployment of HSDPA？
 How to adjust the network plan?
 How to adjust the network construction investment?
 After deployment of HSDPA, any influence towards RNC, CN (capacity, networking)?
 Service type? And subscriber behavior changing caused by HSDPA will generate
new demand of network capacity?

HSDPA network planning case study

ZTE HSDPA Network Planning and Implement
Agenda

 Without considering HSDPA, the 2G transmission resource can be
used by the WCDMA network on Iub interface.
 With HSDPA on the initial phase of WCDMA network construction,
higher requirements are needed for the transmission resource on the
Iub interface!
 “3G(network) makes use of 2G(transmission resource) during the
initial phase while the 2G makes use of 3G during the later phase”
is not true any more!
 The transmission capacity expansion or even the new
transmission resource is necessary on Iub interface.
Transmission resource on Iub and 2G

 The ATM service process modules of MSTP devices endow the 3G
transmission network with the same functions as those of the ATM switching
but lower cost.
 Basing on the MSTP platform, ATM VP-Ring can be established to improve
the transmission efficiency of the dynamic services and protect the ring
network at the same time.
MSTP--the networking technology of WCDMA
transmission network

For capacity
 R99 cell peak data rate:
7×384Kbps=2.688Mbps
 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
For traffic mode
 The PS traffic mode will change greatly,
more PS traffic will rush into HSDPA
system
 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
HSDPA requires more transmission resource, because of the changing
of capacity of Node B and traffic mode
HSDPA transmission solution

Conclusions of HSDPA network
planning and establishment
 A complementary relationship is existed between HSDPA and R99/R4
on the throughput efficiency and coverage.
 Great attention should be attached to the carrier planning and handover
scheme when designing the HSDPA network with R99/R4.
 The network potential values can be improved a lot, while HSDPA is
realized according to the sites of R99/R4.
 HSDPA is mainly implemented in the urban area. Indoor coverage and
outdoor hotspot coverage are of especial importance.
 More attention should be paid on the transmission resource of Iub
interface when introducing HSDPA into the network construction.

 The introduction of HSDPA increases 3 HSDPA-related physical
channels. Thus, R99 RMM algorithm should be upgraded!
HSDPA influence on the RMM
algorithm of R99/R4
 Add special processing method on code resource management for HS-
PDSCH and HS-SCCH
 Add admission control on HS-DSCH
 Add HSDPA power control method
 Add DRBC (Dynamic Radio Bearer Control) after the introduction of HS-
DSCH
 Handover policy should be upgraded
 Load balance policy should be upgraded, e.g. the status transferring
between HS-DSCH and DCH
 Update congestion control
 Update load control

 After the introduction of HSDPA, more deep research and
discussion on how to optimize and allocate the radio
resource of HS-DSCH and DCH should be carried out in
order to make full use of the advantages of HSDPA.
 The radio resource balance between DCH and HS-DSCH
 The balance between power resource and code resource

such as power, channel code, etc.
 Dynamic Configuration: System will adjust the allocation of the resources (power,
channel code, etc.) between the R99 services and HSDPA services according to the
load status.
 It is simple, stable and reliable for the static configuration. As for the dynamic
method, more complexity will result in the improvement of the efficiency of resource
usage.
 Use the same carrier for HSDPA and R99:
 With static configuration, the allocation of radio resources for HSDPA and R99 is
made according to the forecast of the traffic model.
 With dynamic configuration, there is no need for the precise forecast of the traffic
model.
 Under the co-carrier environment, the dynamic method is recommended.
 HSDPA use independent carrier (There are enough carrier available):
 CS services are not supported. Only support data card for PS service.
 Either static or dynamic configuration is suitable.

The powerful RMM algorithms
make the efficiency of resource
usage higher and the control of
resource more flexible. The
algorithms can be modified or
customized according to the
requirements of operators.
Conclusion of HSDPA RRM

ZTE serialized Node B support
HSDPA flexible update

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!
