A method for allocating pilot subcarriers in a resource block for a wideband wireless mobile communication system using an orthogonal frequency division multiplexing (OFDMA) modulation is discussed. In this method, pilot subcarriers are allocated in the resource block so that a group of consecutive data subcarriers separated from adjacent other group of consecutive data subcarriers by the pilot subcarriers has even number of subcarriers within an OFDMA symbol.

A method and device for wirelessly communicating between a mobile communication terminal and a base station, including exchanging one or more resource units between the base station and the mobile communication terminal, each resource unit having 18 subcarriers by a plurality of Orthogonal Frequency Division Multiple Access (OFDMA) symbols. The one or more resource units are permutated using X contiguous subcarriers as a permutation unit in each OFDMA symbol, wherein X is a positive integer that is a multiple of 2 as well as a divisor of 18.
