The statement A is incorrect. The larger the subcarrier spacing [1], the shorter the symbol duration
on each subcarrier, not the larger number of symbols. Statement B is also incorrect. The larger the
subcarrier spacing [1], the larger the CP length and the more suitable it becomes for wide coverage.
Statement C is correct. The smaller the subcarrier spacing, the lower the power spectral density.
Statement D is incorrect. The larger the subcarrier spacing [1], the shorter the slot length.
