<p>PURPOSE: A method for a down link bandwidth in an orthogonal frequency division multiplexing access system are provided to increase the throughput of down link data of a wireless resource by minimizing the waste of radio resources. CONSTITUTION: A base station schedule distinguishes MPDU with a DIUC(Downlink Interval Usage Code) and stores divided MPDU(S310). At least one data bus is formed by connecting the stored MPDU(S320). A sub-channel mode of data bus is instituted(S330). The allocation number of a slot is calculated(S340). The number of the sub-channel data bus is calculated by assigning the data bus to the sub-channel(S350). The sub-channel offset of data bus is instituted(S360). The sub-channel number and sub-channel offset information are stored in down link map information(S370).</p> |
