Specifically, the sizes of the frequency resources of the first OFDM system, which corresponds to an existing OFDM, and the second OFDM system, which corresponds to a UF-OFDM, are determined. Adjacent subcarriers are instructed to allocate any one of a guard carrier and a subcarrier to which null data is allocated, while performing frequency resource allocation between the first and second OFDM systems in accordance with the determined sizes of the frequency resources.
