Abstract

Disclosed is a method for configuring an uplink frame in an OFDMA based wireless communication system. The total band of the uplink frame is divided into a predetermined number of subcarrier groups. Subcarriers within the respective allocated subcarrier groups are allocated to the subchannel defined for a predetermined number of consecutive symbols defined by slots in the uplink frame. Pilot subcarriers are allocated by the unit of the predetermined number of symbols so as to allow channel estimation from among the allocated subcarriers. Accordingly, data subcarriers are allocated by minimizing collision with specific users of adjacent cells so as to enable channel estimation using preambles in a cellular system, and some positions of the data subcarriers are allocated for pilots, thereby allowing synchronous demodulation and improving frequency reuse rates.
