7. HSPA+: A Strong Evolution Path For Peak
Throughputs
168 Mbps HSPA+ R10: 20 MHz Multicarrier
• Expands HSPA+ to 20 MHz deployments
• Evolution to femtocell networks
HSPA+ R9 & R10: Expands Multicarrier
HSPA+ R9: Expands 10 MHz Multicarrier
84 Mbps
• Enhanced performance in 10 MHz
• Uplink multicarrier
• MIMO support with multicarrier
• Multi band multicarrier—aggregation across bands
HSPA+ R8: 10 MHz Multicarrier (dual carrier)
42 Mbps
• Enhances broadband experience
•Doubles data rates to all users
28 Mbps • Doubles bursty application capacity
• Standardized femtocell support
14.4 Mbps
HSPA+ R7: Next Gen. Performance Today
• Doubles data capacity
23 Mbps • More than doubles voice capacity
• Similar HSPA+ and LTE performance
5.7 Mbps 11 Mbps • The natural evolution at a lower cost
384 Kbps
Rel - 5 Rel - 6 Rel - 7 Rel - 8 Rel - 9 Rel – 10
HSPA HSPA +
Notes: R8 will reach 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach
7 84 Mbps peak rates. Uplink multicarrier double the uplink peak data rate to 23 Mbps in 10 MHz in R9. R10 expands multicarrier to 20 MHz to potentially reach 168 Mbps when using MIMO.
