1. A transmission method according to Frequency-Division Multiplexing (FDM), the transmission method comprising:
selecting a pattern from among resource allocation patterns, the resource allocation patterns defining respective allocations of Orthogonal Frequency-Division Multiplexing (OFDM) subcarriers to subcarrier groups;
mapping data groups onto the subcarrier groups according to the selected pattern to perform Frequency-Division Multiplexing (FDM); and
transmitting allocation information and the mapped data groups according to OFDM, the allocation information indicating the selected pattern, wherein
the subcarrier groups include a fixed subcarrier group having fixed OFDM subcarriers regardless of the selected pattern, the fixed OFDM subcarriers are fixed in a frequency direction, and a data group among the data groups is mapped onto the fixed subcarrier group,
the number of the fixed OFDM subcarriers is fixed regardless of the selected pattern, and
the allocations of the OFDM subcarriers defined by the respective resource allocation patterns are mutually different in a frequency direction.
