A method of multiplexing scaled numerology OFDM waveforms in an orthogonal frequency division multiplexing is presented. A first data can be encoded into a first numerology at a first set of tones and a second data can be encoded into a second numerology at second set of tones. A third data can be encoded into a guard band in such a way that the third data can be interpreted under either the first numerology or the second numerology.
