The HSPA+ Evolution Getting Even Stronger

Notes: R8 reaches 42 Mbps by combining 2x2 MIMO and 64QAM), or by utilizing 64QAM and multicarrier in 10 MHz. R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps. Uplink multicarrier doubles the

uplink to 23 Mbps in R9. R10 expands multicarrier to 20 MHz to reach 168 Mbps. R11 expands multicarrier to 40 MHz to reach 336 Mbps. 69 Mbps in the uplink is reached by combining uplink 2x2 MIMO and 64 QAM

1Additional spectrum bands and band combinations continuously defined in 3GPP. 2Non-contiguous aggregation within a band are planned for R11. The core support is already part of

R10 (signaling ,device capability), but additional non-contiguous band combinations need to be defined for R11.3For typical bursty applications and typical partial carrier load.

Aggregate Unpaired Spectrum for More Downlink Capacity—Supplemental Downlink

1HSPA+ aggregation across bands already supported in 3GPP R9 with 2 bands, but each additional band combination has to be defined in 3GPP. 2The expansion of dual-carrier in

R10 (4x) and R11 (8x) beyond allow additional unpaired spectrum aggregation . 3L-Band in Europe:1452 MHZ to 1492 MHz.

L-Band (1.4GHz) Key Opportunity2

Harmonization ongoing in Europe and beyond, up to 40 MHz unpaired spectrum available3

Other opportunities, such as 700MHz in the US, depend upon country-specific spectrum situations

discontinuous transmission when there is no data to transmit). HSPA+ R8 introduced HS-FACH with DRX and uplink HS-RACH. 3For Social networking, gain depends on application
