A downlink power control method and apparatus for improving downlink power efficiency gain in an Orthogonal Frequency Division Multiplexing (OFDM) system is provided. The downlink power control method includes transmitting a downlink data channel at a normal subframe according to first downlink power information for the normal subframe, and transmitting the downlink data channel at an Almost Blank Subframe (ABS) according to second downlink power information for the ABS, wherein the first downlink power information for the normal subframe and the second downlink power information for the ABS differ from each other. The downlink power control method and apparatus is capable of regulating inter-cell interference variation between contiguous symbols at a predetermined level in a subframe at a terminal of a neighbor cell and making it possible to schedule the UE receiving the low power data channel using the power ratio of the feedbacks from the UE.
