Abstract  Abstract

The present invention divides an entire frequency band into a plurality of subcarrier bands, and includes a subchannel that is a set number of the subcarrier bands. A method of allocating subchannels, the method comprising: classifying the subcarrier bands in a preset period to generate the same number of subcarrier groups as the number of the base stations, and for a specific base station at a first time point, Detecting corresponding subcarrier bands in each of the groups according to a sequence, allocating the subcarrier bands detected in each of the groups as a subchannel for the specific base station, and immediately after the first time point Configures a subchannel allocated for the specific base station in Groups to which each of the subcarrier bands belonging are set differently from groups to which each of the subcarrier bands constituting the subchannel allocated for the specific base station belongs to the subchannel for the specific base station. It is characterized by including the process.

Subchannel, time-frequency domain, two-dimensional subchannel allocation, galoa field, subchannel allocator, group index interleaving, diversity gain
