A timing adjustment value is received, and from the received timing adjustment value is determined an integer portion and a fractional portion. In the frequency domain, the determined fractional portion is applied by rotating a signal. Optionally, a phase shift may also be imposed with the rotation. In the time domain, the determined integer portion is applied by one of inserting samples in the rotated signal or removing samples from the rotated signal in an amount corresponding to the determined integer portion. After the signal rotation to apply the fractional portion, the active sub-carriers are mapped, and the transition from frequency domain to time domain occurs by means of an inverse Fourier transform. A cyclic prefix CP may be added after the Fourier transform, separately or functionally combined with the integer portion shift by modifying the size of the CP to impose the determined integer portion. After other conventional processing known in the art, the rotated signal as advanced/delayed by the sample removal/addition is then transmitted.
