This page on LTE bandwidth vs sampling frequency vs resource block covers relation betweenLTEbandwidth,sampling frequency and resource block. Please check table below for values. For example 512 point FFT case,bandwidth is 5MHz, sampling frequency is 7.68MHz and number of resource blocks are 25. Please check our page onLTETerminologyfor description of these terms.
| Channel Bandwidth(MHz) | 1.4 | 3 | 5 | 10 | 15 | 20 |
|---|---|---|---|---|---|---|
| No. of Resource Block(NRB) | 6 | 15 | 25 | 50 | 75 | 100 |
| No. of occupied subcarriers | 72 | 180 | 300 | 600 | 900 | 1200 |
| IFFT(Tx) /FFT size(Rx) | 128 | 256 | 512 | 1024 | 1536 | 2048 |
