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

Multicarrier to Leverage All Spectrum Assets
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

MultiFlow Utilizes Unused Capacity
1Different Data From Multiple Cells in the downlink- an evolution of multicarrier. Receive diversity with interference suppression (Type 3i receiver) required.
Heavy Load Medium Load Light Load
Typically uneven load that changes with time and location

Today’s devices can only be served by one downlink cell—that could be heavily loaded.

MultiFlow Benefits All Deployments
1Benefits also HetNets (mix of macro networks with added small cells like picocells) due to more overlapping coverage with small cells and ability to select best link.

It’s not just about adding small cells!— Optimizations Further Improve HetNets
Today: Dual-Carrier and Reduced Macro Power Even Better with MultiFlow—Balances Uneven Load Advanced Device Receivers Provide Additional Gain
HetNet Range Expansion Can Be Done Today:
Note: Self-Organizing Networks (SON) techniques can also improve Heterogeneous networks (HetNets) and are standardized already in R10, such as Minimization of Drive Tests (MDT) and Automatic Neighbor Relation (ANR)

ACCOMMODATING THE SMARTPHONE AND M2M GROWTH
R7/R8 R11
Significantly reduced signaling load
(for small bursts, background)
Extended battery life for all applications (for all non full-buffer)2
1R7/R8 allows small amounts of data to be efficiently transported in CELL-FACH state : up to 90% reduction in network signaling load due for social media example. 2Cell-DCH w/ R7 CPC allows non full buffer apps to use connected mode, DCH, more efficiently (DTX/DRX). 3A main enhancements is downlink triggered feedback (CQI) and acknowledgements on the FACH reverse link, which makes FACH efficient like a regular HSPA link., see simulation assumptions in R1-112679
