1. A method of transmitting symbols by a user equipment in a wireless communication system, the method comprising:

  • receiving a timing adjustment command from a base station, the timing adjustment command advancing a transmission timing of uplink transmission;

    generating a first symbol by adding a first cyclic prefix (CP) to a first inverse fourier transformed samples, the first CP being copied from the first inverse fourier transformed samples;

    generating a second symbol by adding a second CP to a second inverse fourier transformed samples, the second CP being copied from the second inverse fourier transformed samples,wherein the timing adjustment command is applied starting from the second symbol;

    forming a modified second symbol by removing samples overlapped with the first symbol from the second symbol when the first symbol and the second symbol are overlapped due to the timing adjustment; and

    transmitting the first symbol and the modified second symbol to the base station,wherein the transmitted first symbol has a complete size and the transmitted modified second symbol has a partial size.
