Introduce HSDPA to WCDMA

Driver to HSDPA

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. Pay more attention to it



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

Time fairness

Traffic fairness

Every user get equal service time, but the traffic maybe 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 channel state

Max-C/I

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

Proportional 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.

Intra-frequency plan

Resource condition

Advantage and disadvantage

Recommended deployment

Less inter-frequency handover, admission control, load control and power control can be achieved within one same frequency cell.

Advantage: easy to do resource control

After the network construction finished, to achieve the high demand of voice and PS downlink.

Situation I: if HSDPA frequency point support normal handset, all the resource have to be assigned within various different frequency cells.

Advantage: voice user +HSDPA users get good service

F2: HSDPA+R99/R4

F1: R99/R4 Inter-frequency plan F2: HSDPA

Phase I :several hot spot, and the important building to deploy HSDPA

ZTE solution

Situation II: HSDPA frequency point are only used for PC card, resource management can be achieved more easily.

Disadvantage: do not have user detail classification

With the development of 3G, to provide dedicated frequency point for HSDPA PC card (only PS domain)

Disadvantage: resource control will be difficult in situation I, maybe some frequency point resource will be wasted at the beginning

Phase II :all the hot spot and several macro sites to deploy HSDPA

HSDPA Solution

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.

HSDPA Solution

HSDPA transmission solution HSDPA requires more transmission resource, because of the changing of capacity of Node B and traffic mode For capacity 

R99 cell peak data rate: 7×384Kbps=2.688Mbps



HSDPA cell peak data rate:

For traffic mode 

The PS traffic mode will change greatly, more PS traffic will rush into HSDPA system

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

 Advanced design ， HSDPA functions have been embedded into hardware.  Just update software to support HSDPA functions.  No additional hardware is needed!

HSDPA Solution

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!
