1. A method for transmitting a code sequence from a transmitting party to a receiving party in a wireless communication system, the method comprising:

  • acquiring a code sequence having a second length by a cyclic extension of a code sequence having a first length;

    performing a circular shift to the code sequence having the second length; and

    transmitting the circular shifted code sequence having the second length to the receiving party,wherein the first length is a largest prime number smaller than the second length, andwherein the cyclic extension of the code sequence having the first length is performed such that a part of the code sequence having the first length, having a length corresponding to a difference between the first length and the second length, is added to either a start or an end of the code sequence having the first length, andwherein the circular shift is performed to the code sequence having the second length such that either a rear portion of the code sequence having the second length moves to a start of the code sequence having the second length, or a front portion of the code sequence having the second length moves to an end of the code sequence having the second length.
