Abstract:
1. A method for configuring a subchannel in a broadband wireless access communication system, which includes a plurality of cells distinguished by cell identifications and has an entire frequency band divided into a plurality of sub-carrier bands, said system further includes a subchannel/subcarrier allocator, which performs said method, the method comprising the steps of: generating a plurality of subchannels based on a predetermined subchannel configuration scheme in each of the cells included in the communication system; determining a predetermined number of subchannels from among the generated subchannels as soft handover subchannels; renumbering indexes of sub-carrier bands included in remaining subchannels except for the subchannels determined as the soft handover subchannels; and generating a plurality of non-soft handover subchannels including different sub-carrier bands depending on the cells, by using a specific cell identification of each cell and the renumbered indexes of sub-carrier bands, wherein the subchannel configuration scheme is determined by: and wherein ‘subcarrier (k,s)’ represents an index of a k
