I'm a novice to LTEⁱ. During my studies, I had this doubt and I thought of putting it here for some clarifications in the LTE Resource mapping side. I want to know how is the data( in bits) getting mapped onto the RE's. Is it like first all the 12 sub-carriers of the zeroth symbol in the RBⁱ is filled up and then the 12 sub-carriers of the first symbol?? or is it like first all the 7(Normal CP Case) symbols of first subcarrier gets filled up then second, third, fourth subcarrier etc., To summarise my question Whether the data gets mapped row wise or column wise? Any help will be appreciated. Thank you
