6. Evolution of TD-SCDMA Technology
Data rate
LTE TDD DL/UL: 129/50 Mbps
over 20MHz, R’8
DL/UL: 8.4/5 Mbps
HSPA+ over 1.6MHz. R’8
MC-HSDPA/HSUPA
(CCSA only!)
DL/UL: 2.8/2.2 Mbps
HSDPA/HSUPA over 1.6 MHz, R’5/R’7
LCR 384kbps over 1.6MHz, R’4
higher coverage/spectrum efficiency/peak data rate, lower delay/cost.

CS and PS Data
p
HSDPA: DL peak data rate per 1.6MHz is 2.8Mbps
p
MBMS: optimization of broadcasting capability
p
HSUPA: UL peak data rate per 1.6MHz is 2.2 Mbps
p
MBMS improvement: dedicated carrier MBMS, improved efficiency, wider
p
coverage
N-frequency HSDPA: HSDPA over N-frequency system, improved peak data
p
rate.

8. 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)
8.4 Mbps in downlink, 5 Mbps in uplink over 1.6MHz (single carrier), equivalent
p
to 105 Mbps over 20MHz
MIMO and 64QAM modulation as enabling technologies for high spectral
p
efficiency
CPC (Continuous Packet Connectivity) will optimize the networks to support
p
VoIP, streaming and other real time services
Cell FACH enhancement: Enable quot;always onlinequot; type services for UEs, which
p
allow for an excellent user experience in web surfing, chatting, gaming etc.

10. HSPA+ : Operator Benefits
HSPA+ is a fully TD-SCDMA Rel.4/5/6 backward compatible technology
p
Protection of investment for the operators: HSPA+ is mainly software
p
upgrade, no change in infrastructure.
Short time-to-market: quick response to the market requirement.
p
Operators can swiftly upgrade the existing network to HSPA+ in order to
promote new services.
Lower technical risk: HSPA+ is the gradual evolution from release
p
4/5/6/7 so the technology itself is very mature and the network is
evolved from the mature commercial TD-SCDMA network.
HSPA+ is perfect solution for transitional period before LTE is
p
commercially available.

18. 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
