For example, control data may be transmitted using OFDM symbols of a first size, user data may be transmitted using OFDM symbols of the first size and a second size, and pilot data may be transmitted using OFDM symbols of a third size or the first size. In one exemplary design, a ...

The Resource Type may have values as high as 1023 per symbol depending on the FFT size. For certain advanced configurations (described later in this note), the Resource Type is treated as a 10-bit number, with the higher-level bits used to indicate items such as user number,MIMOantenna nu...

2048 time samples from IFFT module fit into symbol period of 1/(15KHz). The sampling frequency hence is (15KHz * 2048) for 20 MHz. Similarly by changing the number of sub-carriers you will get the sampling freq for other band-widths ...
