Abstract
An apparatus and method for call setup in a wireless communication system are provided. A first Mobile Station (MS) determines a DownLink (DL) duration, performs synchronization, selects one preamble code among a preamble code set reserved for the call setup of the MS out of the cell area, and transmits the selected preamble code during the determined DL duration. A second MS scans a preamble code during the DL duration, determines if the scanned preamble code is a preamble code for the call setup of the MS out of the cell area, and transmits a response message to the preamble code to the first MS.
