1. A transmitting apparatus comprising:
a frequency allocator configured to map signaling data to first subcarriers of a preamble symbol, and map a reference signal to second subcarriers of the preamble symbol; and
a transmitter configured to transmit a frame comprising the preamble symbol and a data symbol to a receiving apparatus,
wherein the reference signal is used for at least one of channel estimation and frequency offset compensation in the receiving apparatus,
wherein the signalling data is used for decoding the data symbol in the receiving apparatus, and
wherein the first subcarriers are positioned at a non-fixed interval in the preamble symbol, and the second subcarriers are positioned at a fixed interval in the preamble symbol.
