Rel.6 Rel.7 HSPA+ LTE

Klaus Maler: TD-SCDMA Evolution

p 8.4 Mbps in downlink, 5 Mbps in uplink over 1.6MHz (single carrier), equivalent to 105 Mbps over 20MHz

p MIMO and 64QAM modulation as enabling technologies for high spectral efficiency

p CPC (Continuous Packet Connectivity) will optimize the networks to support VoIP, streaming and other real time services

p Cell FACH enhancement: Enable "always online" type services for UEs, which allow for an excellent user experience in web surfing, chatting, gaming etc.

One Step Forward - HSPA+

Market Requirement: Higher peak data rate and increased spectral efficiency in deployed TD-SCDMA networks.

TD Tech’s Solution: HSPA+ (Enhanced High Speed Packet Access)

Rel.6 Rel.7 HSPA+ LTE

Klaus Maler: TD-SCDMA Evolution

p 2X2 MIMO system doubles spectrum efficiency.p Integration possible with existing TD-SCDMA smart antenna system, no change

in deployed antenna hardware

p HSPA+ is a fully TD-SCDMA Rel.4/5/6 backward compatible technologyp Protection of investment for the operators: HSPA+ is mainly software

upgrade, no change in infrastructure.p Short time-to-market: quick response to the market requirement.

Operators can swiftly upgrade the existing network to HSPA+ in order to promote new services.

p Lower technical risk: HSPA+ is the gradual evolution from release 4/5/6/7 so the technology itself is very mature and the network is evolved from the mature commercial TD-SCDMA network.

p HSPA+ is perfect solution for transitional period before LTE is commercially available.

HSPA+ : Operator Benefits

Klaus Maler: TD-SCDMA Evolution

New access technology and new system architecture for mobile radio network competitiveness in 2011 and 10 years beyond.

Conclusions

• Standardized and smooth upgrade path from existing TD-SCDMA networks towards future TDD based technologies

• HSPA+ is the key technology to fill the gap between TD-SCDMA and LTE

• HSPA+ will protect the operator investment and provides future proof services and performance

• LTE TDD will co-exist and supplement TD-SCDMA for future deployments
