1. A transmitting method for transmitting an orthogonal frequency-division multiplexing (OFDM) signal, the transmitting method comprising:
generating a second preamble and data symbols, the data symbols including time-frequency resources provided for data transmission, first modulated signals of a first Physical Layer Pipe (PLP) being mapped onto the time-frequency resources corresponding to a first frequency range within an entirety of the data symbols, and second modulated signals of a second PLP being mapped onto the time-frequency resources corresponding to a second frequency range within the entirety of the data symbols;
performing an Inverse Fast Fourier Transform (IFFT) processing on the second preamble and the data symbols;
generating a first preamble followed by the second preamble and the data symbols; and
transmitting the first preamble, the second preamble, and the data symbols, wherein
the second preamble includes first information, for each of the first PLP and the second PLP, and second information,
the first information indicates a head position in time, a head position in frequency, and the number of time resources of corresponding PLP, and
the second information indicates FFT size of the data symbols.
