Abstract: An apparatus and a method are provided in which a processor of a receiving apparatus regenerates time domain samples of an interfering data numerology from frequency domain received signals. The processor performs pre-fast Fourier transform (FFT) processing of a desired data numerology on the regenerated time domain samples of the interfering data numerology. The processor performs FFT, with a size corresponding to the desired data numerology, on the regenerated time domain samples after performing pre-FFT processing to generate an interfering numerology cancelation signal. The processor subtracts the interfering numerology cancelation signal from a frequency domain received signal of the desired data numerology to reduce an effect of interference of the interfering data numerology on the desired data numerology.
