PROBLEM TO BE SOLVED: To provide a method and apparatus for generating a ranging preamble code in a wireless communication system. SOLUTION: A terminal generates a ZC (Zadoff-Chu) sequence, in which a cyclic shift is applied to each of a plurality of OFDMA (Orthogonal Frequency Division Multiple Access) symbols, as a ranging preamble code. The cyclic shift is applied for each OFDMA symbol. COPYRIGHT: (C)2011,JPO&INPIT |
