Claim Text:
1. A method for transmitting a signal at a base station in a mobile communication system, the method comprising: performing repetition coding on an information bit to generate a plurality of information bits; obtaining a plurality of modulation symbols from the plurality of information bits; mapping the plurality of modulation symbols to one or more orthogonal frequency division multiplexing (OFDM) symbols; and transmitting the plurality of mapped modulation symbols, wherein the plurality of modulation symbols are mapped separately from each other in a frequency domain when the plurality of modulation symbols are mapped to one OFDM symbol, and wherein at least two of the plurality of modulation symbols are mapped separately from each other in the frequency domain to a same OFDM symbol when the plurality of modulation symbols are mapped to two OFDM symbols.
