1. A method within an apparatus, comprising:

  • determining a first set of subcarriers corresponding to at least one carrier in a spectral allocation;

    determining a second set of subcarriers corresponding to remaining usable subcarriers in the spectral allocation; and

    generating an output waveform for simultaneous transmission comprising mixed code division multiplexing (CDM) data and orthogonal frequency division multiplexing (OFDM) data on the first set of subcarriers, OFDM data on the second set of subcarriers and OFDM data on a third set of subcarriers in an overhead interval, wherein a half-slot in a carrier of the at least one carrier comprises at least two traffic segments, and wherein a first segment of the at least two traffic segments comprises CDM data and a second segment of the at least two traffic segments comprises OFDM data, wherein generating the output waveform further comprises generating overhead data for the third set of subcarriers in the overhead interval.
