Abstract:
1. A method for detecting a segment identity by a mobile station in a wireless communication system, comprising: acquiring a cell identity and the segment identity corresponding to the cell identity from a Secondary Advanced (SA)-preamble sequence received from a base station, wherein the segment identity is one of first, second or third identities; determining a frequency reuse factor of the base station as being 2 or 3; and if the frequency reuse factor is 2 and the acquired segment identity is the third segment identity, converting the segment identity corresponding to the cell identity into the first segment identity or the second segment identity, wherein, if the frequency reuse factor of the base station is 3, an SA-preamble sequence of a cell identity x included in one segment identity has a complex conjugate relationship with an SA-preamble sequence of a cell identity x+128 included in the one segment identity, and the one segment identity includes 256 cell identities, and wherein the converting the segment identity is performed according to the following Equation: Equation where values of the first, second, and third segment identities are 0, 1, and 2, respectively, IDCell indicates the cell identity, and the segment ID indicates a converted segment identity.
