Pi=Probability of occurrence of a specific SINR value at cell edge obtained using simulations
\nRi=Average throughput corresponding to SINR range<\/p>\n

Let us consider the following distribution for the SINR at the cell edge:<\/p>\n

P1=0.5 (SINR=1.50-3.50 dB)
\nP2=0.25 (SINR=3.50-7.00 dB)
\nP3=0.15 (SINR=7.00-9.50 dB)
\nP4=0.10 (SINR=9.50-11.50 dB)<\/p>\n

Cell Throughput=(0.50*4)+(0.25*6)+(0.15*8)+(0.10*12)=5.9 Mbps<\/p>\n

Note: This throughput is much less than the theoretical maximum which assumes that the full 20 MHz bandwidth is being utilized in a 4×4 MIMO configuration.<\/p>\n
