Abstract:
1. A method for assigning frequency spectrum bandwidth of an OFDM and OFDMA coexistence system, and the coexistence system comprises a base station system, characterized in that the base station system combines uplink and downlink data containing an OFDM sub-frame and an OFDMA sub-frame in a time division fashion, constitutes a frame structure realizing the coexistence of the OFDM and the OFDMA, and assigns the frequency spectrum according to the different bandwidth requirements of the OFDM and the OFDMA and the use situation of the frequency band; when the total frequency bands of the OFDM and the OFDMA are the same and the bandwidths of the OFDM and the OFDMA are different, the method for assigning the frequency spectrum bandwidth of the system comprises the following steps:
