This page on LTE bandwidth vs sampling frequency vs resource block covers relation between LTE bandwidth,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 on LTE Terminology for description of these terms.
