DESCRIPTION

1Time-slot=0.5ms(i.e1Sub-frame=1ms)1Time-slot=7 Modulation Symbols (when normal CP length is used)1 Modulation Symbol=6 bits; if 64 QAM is used as modulation schemeData rate for a single carrier=Number of symbols per time slot*Bits per symbol/Duration of a time slot=7*6/0.5e-3=84kbpsIf 1200 carriers (100RBs) are used then the aggregated throughput would be=1200*84kbps=100.8Mbps
