Mobile Data Services Leading the Future

Global mobile data has nearly tripled in the last year, growing more than 10 times faster than voice.

Total data traffic volume in 2015 will be more than 30 times that of 2010. Operators will need to

make capital investments to increase capacity in order to meet this demand

Operator’s choice and progress on HSPA+ Road

100% WCDMA operators have launched HSPA.

Almost 50% of HSPA operators have launched HSPA+.

Operators are primarily interested in 64QAM, followed by DC-HSPA and then MIMO-related enhancements.

Operators also paid lots of interests in PS service enhancement， such as CPC features.

Operators generally cautious about using HSPA+ for voice services.

2x2 MIMO Principle

MIMO(Multi Input Multi Output) uses multiple antennas respectively at the transmitting end and receiving end to speed up downlink date bit rate, decrease BER and improve QoS.

Two streams (two transmission block) are transmitted simultaneously in 2ms through two antennas, getting spatial diversity gain, improve the peak rate and data throughput.

amplitude modulated signal will form the waveform just like

64QAM.

HSPA+ will be deployed firstly in areas where there are heavy data service requirement including capacity and

user experience enhancement, including indoor areas such as office building, public stadium, airport, government

office and high level residential area, and outdoor hotspots such as CBD, public marketplace, scenic spots and schools.

Secondly urban and some import transport line such as highway and high-railway.

Finally whole network coverage will be reached.

DL 64QAM Deployment Proposals

Deploy Strategy Based on Areas

Deploy Strategy Based on Frequency

Scenario 1: Single carrier, all cells or partial cells may support R99/HSPA/HSPA+ (64QAM) services It is always first step for HSPA+ deployment

Scenario 2 Another new carrier is introduced to support HSPA/HSPA+ (64QAM) It is always adopted in CBD, indoor stadium where exist heavy data traffic.

Scenario 3 Both the existing and another new carrier are upgraded to support HSPA/HSPA+(64QAM) It is always adopted when operators planned network expansion and HSPA+ capability upgrade together

scheduler for each new transmission interval

according to UE capability and radio condition.

For sites need to provide DL peak rate

experience, suggest to extend the

Scenario 1: Upgrade the existing part of cells (or all cells) to support R99/HSPA/HSPA+ (MIMO) while the others still support R99/HSPA. This scenario always happens in MIMO pre-commercial period or MIMO initial stage

Scenario 2 : One dedicated MIMO carrier is introduced to support HSPA/HSPA+ (MIMO). This scenario always happens in hotspots such as CBD, in-building Stadium with high data traffic requirement.

Scenario 3 : One dedicated MIMO carrier is introduced to support HSPA+(MIMO) only. This scenario always happens when MIMO is mature and there are a lot of MIMO terminals in industry.

DC-HSUPA could enhance the whole cell capacity .

With the increase of user number, the station spacing, DC-HSUPA

gain against HSUPA would decreases.

When the station spacing is large, the transfer power of users at

the cell edge users will be insufficient so to affect the throughput

of DC-HSUPA, even get negative gain.
