Patent ID: 7633900

Claim:
A method for assigning subchannels to each of a plurality of base stations included in a wireless communication system that divides an entire frequency band into a plurality of subcarrier bands and includes a plurality of subchannels, each of which is a set of a predetermined number of the subcarrier bands, the method comprising the steps of: classifying the subcarrier bands in a predetermined period; generating a number of subcarrier groups by dividing the predetermined period into a predetermined number of time periods; detecting corresponding subcarrier bands, for a particular base station, from each of the subcarrier groups according to a predetermined sequence; and assigning the subcarrier bands detected from each of the groups as a subchannel for the particular base station, wherein the predetermined sequence is expressed as S 0 =α, α 2 , α 3 , . . . , α Q−2 , α Q−1 , where S 0 denotes the predetermined sequence, Q denotes a size of a Galois Field, and α denotes a primitive element of a Galois Field (Q).
