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 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.

Pay more attention to it

Key technology: AMC (1)

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, the service bearing ability of one channel is further larger than R99/R4

by using more efficient modulation and coding rate, while SF is twice as R99/R4

Time fairness

Traffic fairness

Max-C/I

Proportional fairness

Every user get equal service time, but the trafficmaybe not equal, the fairest algorithm but has the

lowest traffic

Every user get the same traffic, but the time maybe

not equal, has the lower utility of system resource

because it will schedule the UE with bad channelstate

Only the user in best channel state (biggest C/I) will

get the service priority in each turn, the biggest traffic

but has the worst fairness

Weighted compromise of above algorithms and has

bigger system traffic and better service fairness

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.

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 networkshould adopt HSDPA function, with soft smooth upgrade ability

HSDPA is not constructed as a individual network, HSDPA is an enhanced

technology of WCDMA (throughput, users)

Network construction and plan for R99 and HSDPA based on the one-shotplanning, 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.

the indices of indoor distributedcomponents (like power distributor)

required by HSDPA and R99 are same,

So the existing indoor distributed system

of R99/R4 is suitable for HSDPA

For capacity

R99 cell peak data rate:

7384Kbps=2.688Mbps

HSDPA cell peak data rate:15960Kbps3/4 = 10.8 Mbps

Peak throughput of HSDPA cell is

4 times as that of R99 cell

Peak traffic of 3CS HSDPA Node

B:10.831.380% 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
