ABSTRACT:
Provided is a method for hopping frequencies of an OFDM (orthogonal-frequency-division-multiplexing) symbol, including: receiving an OFDM symbol comprising mapping information as to a type of disposing sub-carriers of the OFDM symbol, a frequency hopping pattern, and positions of pilots; and mapping the type, the frequency hopping pattern, and the positions of the pilots based on the mapping information.
