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)
2007 2008 2009 2011
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
MIMO for HSPA+: Multiple In – Multiple Out
N transmitting antennae and M receiving antennae system

Klaus Maler: TD-SCDMA Evolution
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.
TDD Long Term Evolution
p Radio Side (LTE – Long Term Evolution)n Improvements in spectral efficiency, user throughput, latencyn Simplification of the radio networkn Efficient support of packet based services: MBMS, IMS, etc.
p Network Side (SAE – System Architecture Evolution)n Improvement in latency, capacity, throughputn Simplification of the core networkn Optimization for IP traffic and servicesn Simplified support and handover to non-3GPP access technologies
