1. A method for generating a preamble for a random access, performed by a user equipment (UE) having a plurality of antennas, in a wireless communication system, the method comprising:

  • dividing a preamble sequence into sequence subsetsgenerating preambles by using the sequence subsets, each of the preambles corresponding to each of the plurality of antennas; and

    transmitting the preambles simultaneously through the plurality of antennas,wherein the sequence subsets are generated by puncturing the preamble sequence such that the sequence subsets are disjoint each other and,wherein the preambles are transmitted by using different subcarrier sets each other.
