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 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.

Qualcomm simulations. Each scenario is based on the same total number of users (eight users) per carrier. Shows the burst data rate for the 10% best users , the median users and the 10% worst (cell edge) users. MIMO with Multicarrier is part of R9 and R10, but MIMO has not been considered in this simulation.

Expands HSPA+ to 20 MHz deployments Evolution to femtocell networks
LTE relative performance decreases with bandwidth due to higher overhead; 40% overhead in 1.4 MHz vs. 25% in 20 MHz results in 25% better relative performance in 20 MHz vs. 1.4 MHz.
