1. A method for transmitting a preamble over a Random Access CHannel (RACH) in a wireless communication system, the method comprising:

  • generating one preamble having a length greater than a length of a sub-frame, and dividing the one preamble into preambles, each of the preambles having a length less than the length of the sub-frame;

    setting different guard times, during which no preamble is transmitted, between the divided preambles; and

    sequentially transmitting the divided preambles over the RACH using different antennas,wherein each guard time is longer than a round-trip delay time of the sub-frame.
