Modulation method and apparatus with consideration of adaptive hybrid automatic repeat request in wireless communication system

A method of a reception end supporting a hybrid modulation technique in which different types of modulation schemes are mixed, the method comprising:

• collecting information of a channel state with a transmission end;
• determining at least one of an entire modulation order of the hybrid modulation technique, a modulation order of a first type of a modulation scheme and a modulation order of a second type of a modulation scheme;
• and
• operating a demodulation scheme corresponding to the hybrid modulation technique based on the determined modulation order,
• wherein the first type of the modulation scheme and the second type of the modulation scheme form the hybrid modulation technique.
