Abstract  Abstract

The present invention divides an entire frequency band into a plurality of subcarrier bands, and includes a subchannel that is a set of a predetermined set number of subcarrier bands in each of the base stations constituting the wireless communication system. The method of allocating the subchannels may include: generating the subcarrier groups having the same number as the number of the base stations by classifying the subcarrier bands in a preset setting interval, and presetting for a specific base station at a specific time point. Detecting corresponding subcarrier bands in each of the groups according to a setting sequence, assigning the subcarrier bands detected in each of the groups as a subchannel for the specific base station, and immediately after the specific time point. Assign for that particular base station at that time Groups to which each of the subcarrier bands constituting the allocated subchannel belong are different from groups to which each of the subcarrier bands constituting the subchannel allocated to the specific base station belong to the specific base station. And assigning the subchannels.
