Abstract: PURPOSE: A power controlled frequency reuse method in OFDMA(Orthogonal Frequency Division Multiple Access) system is provided to allocate a segment of subcarrier set to each cell following a predetermined order, thereby reducing co-channel interference between cells. CONSTITUTION: Subcarriers in a system bandwidth is divided into M sub-channel set(S210). The sub-channel set is divided into M segments(S220). The segments are classified into a plurality of classes(S230). A transmission power is differentially allocated following the classes(S240). A segment allocation sequence is determined by the class which is determined by a cell type and a channel state of a user terminal A subcarrier is allocated to the user terminal according to a determined segment allocation sequence(S250).

Abstract translation: 目的：提供OFDMA（Orthogonal Frequency Division Multiple Access，正交频分多址）系统中的功率控制频率复用方法，以按照预定的顺序向每个小区分配子载波集，从而减少小区之间的同信道干扰。 构成：将系统带宽中的子载波分为M个子信道集（S210）。 子通道组分为M段（S220）。 这些段被分类为多个类（S230）。 在类别之后差分地分配发送功率（S240）。 段分配序列由由用户终端A的小区类型和信道状态确定的类确定，根据所确定的段分配序列将副载波分配给用户终端（S250）。
