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.

11. 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
