A modulation coding scheme (MCS) is selected from i) a first set of MCSs when the selected channel bandwidth is a first channel bandwidth, or ii) a second set of MCSs when the selected channel bandwidth is a second channel bandwidth, wherein the first set of MCSs is different than the second set of MCSs, and the second set of MCSs excludes MCSs from the first set of MCSs that will result in a padding-related constraint not being met when the second channel bandwidth is to be used. Information bits are interleaved, which includes applying a frequency rotation. The information bits are modulated according to the selected MCS. A plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols are generated using the modulated information bits.
