1R8 will reach 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5 MHz, or by utilizing HOM (64QAM) and multicarrier in 10 MHz. 2R9 combines multicarrier and MIMO in 10 MHz to reach 84 Mbps peak rates. Uplink multicarrier double the uplink peak data rate to 23 Mbps.

3Releases beyond R9 may expand multicarrier to 20 MHz and utilize combinations of multicarrier and MIMO to reach data rates exceeding 100 Mbps.

Notes: 1) PA3 and macro cell modes are supposed. 2) Users are uniformly distributed. 2) As can be observed, the DC gain is more pronounced at low load (25% at 2 users/sector) compared to high load (7% at 16 users/sector).

3) DC improvement comes from frequency diversity and better statistical multiplexing

The throughput gain of DC will fast decrease with the cell users increasing

1 R8 will reach 42 Mbps by combining 2x2 MIMO and HOM (64QAM) in 5MHz, or by utilizing HOM (64QAM) and multi carrier in 10 MHz.

2 R9 and beyond may utilize combinations of multi carrier and MIMO to reach 84 Mbps peak rates. Similarly, uplink multi carrier can double the uplink data rates.

3 Peak rates for 10 and 20 MHz FDD using 2x2 MIMO, standard supports 4x4 MIMO enabling peak rates of 300 Mbps. TDD rates are a function of up/downlink asymmetry

4Peak rates can reach or exceed 300 Mbps by aggregating multiple 20 MHz carriers as considered for LTE Advanced (LTE Rel-10).
