Apparatus and method for allocating subchannels adaptively according to frequency reuse rates in an orthogonal frequency division multiple access system

Abstract

An apparatus and method for adaptively allocating subchannels according to frequency reuse rates in an OFDMA system are provided. To allocate one or more subchannels to one or more mobile stations (MS), information related to an optimum frequency reuse factor (FRF) and a modulation scheme is received from the plurality of MSs, the number of subchannels required for each FRF is calculated according to the received information, subchannels are allocated to the base station (BS) for each FRF, based on the calculated subchannel numbers from the BS and neighboring BSs, and the allocated subchannels are allocated to the MSs.
