The method for performing the random access scheme for the multi-channel in the wireless communication system includes randomly generating a backoff counter value to transmit data; adjusting the backoff counter value by taking into account status of a plurality of idle subcarrier sets per backoff slot; when the backoff counter value becomes zero, selecting one or more subcarrier sets to carry the data from the idle subcarrier sets; and transmitting the data through the selected one or more subcarrier sets. The data collision probability between the terminals can be lowered, the channel utility can be enhanced, the transfer rate in the single-channel random access scheme can be raised, and the consumption of the radio resource can be reduced without using signals for the band request and allocation.
