A method and apparatus to allocate a wireless resource in a distributed antenna system of orthogonal frequency division multiplexing is provided to make full use of a restricted wireless resource by allocating subcarrier and power within a subcell with maximum. A first allocation unit(310) divides a total frequency band into a plurality of subcarrier bands so that it is not overlapped with a neighboring base station. A second allocation unit(312) divides the allocated subcarrier band and allocates it to a plurality of repeater stations connected to the base station through an optical fiber selectively. A collection unit(314) obtains channel state information through the repeater station from a mobile terminal of a corresponding domain. A third allocation unit(316) additionally allocates subcarrier to the repeater station base on the obtained channel state. |
