A method for acquiring FFR power pattern of Frequency Partitions (FPs) at a mobile station (MS) in a wireless communication system using Fractional Frequency Reuse (FFR) is disclosed. The method includes receiving a preamble from a base station (BS); and acquiring a FFR power pattern for a reuse-1 partition and reuse-N partitions using the received preamble, wherein the FFR power pattern is determined based on a segment identifier (ID), the reuse-N partitions include N frequency partitions, each frequency partition has a power level with a range of FP1_power level to FPN_power level, a power-boosted FP in the reuse-N partitions is a partition whose power level is the FP1_power level.
