Method and apparatus for configuring a channel using diversity

A method for configuring a channel by using diversity, the method comprising:

• converting k bits of information to be transmitted through a channel to n bits corresponding to code bits;
• selecting m bits from the n bits, and generating a first modulation symbol to transmit the m bits by selecting one of a first resource and a second resource which are different from each other;
• generating a second modulation symbol by using a resource which has not been selected in generating of the first modulation symbol;
• and
• transmitting the first modulation symbol through a first transmission antenna, and transmitting the second modulation symbol through a second transmission antenna,
• wherein the m bit can be indicated by the modulation symbols generated by two transmission antennas and mapping information on the resources used for generating the modulation symbols by the two antennas.
