Abstract
The present invention relates to a method for assigning frequency spectrum bandwidth of an OFDM and OFDMA coexistence system, and the base station system combines uplink and downlink data containing OFDM sub-frames and OFDMA sub-frames in a time division fashion, assigns the frequency spectrum reasonably according to the different bandwidth requirements of the OFDM and the OFDMA and the use condition of the frequency band, and constitutes a frame structure realizing the coexistence of the OFDM and the OFDMA, so as to send the OFDMA uplink/downlink data and the OFDM uplink/downlink data. The method for assigning frequency spectrum bandwidth according to the present invention can achieve a higher frequency spectrum utilization efficiency of an OFDM and OFDMA coexistence system, avoid the waste of the frequency spectrum resource of a service provider; and can also realize more flexible networking.
