My question that I didn't understand is what does it mean number of "OFDM symbol per frame is 1 or two or 3 ..whatever"?

to clear more, lets assume I have pattern of data to transmit : [0 1 0] , and at each frame number of OFDM symbols is 2.

so what does it mean? is it mean the following claim on the data:

the data [0 1 0] will be stored in three frames and at each frame there's two OFDM symbols? so for is instance

0 is stored in frame and it has two OFDM symbols

1 is stored in frame and it has two OFDM symbols

0 is stored in frame and it has two OFDM symbols

So if that's true , what does it mean that 0 have two OFDM symbols? I need to understand what does it mean that certain frame has N OFDM symbols.

Appreciated for any help.
