Method and apparatus for transmitting feedback information

An apparatus for transmitting feedback information to a base station, comprising:

• a receiver that receives feedback channel allocation information having a plurality of transmission cycles corresponding to each of a plurality of payloads regarding the feedback information and classification information regarding a plurality of classes to which the plurality of payloads belong;
• a payload generator that generates the plurality of payloads for the plurality of transmission cycles;
• a bit multiplexer that multiplexes one or more payloads belonging to each of the plurality of classes for the each of the plurality of classes according to the classification information so as to generate a plurality of multiplexed payloads corresponding to each of the plurality of classes for every transmission cycle of each of the plurality of classes;
• a code multiplexer that applies a plurality of codes corresponding to each of the plurality of classes to the plurality of multiplexed payloads so as to generate a code division multiplexing symbol for every feedback cycle according to the transmission cycle of each of the plurality of classes;
• a channel code application unit that applies a scrambling code corresponding to a channel code to the code division multiplexing symbol so as to generate a channel code applied symbol;
• and
• a transmitter that transmits the channel code applied symbol to the base station through a wireless resource,
• wherein the channel allocation information further includes a plurality of transmission power information sets corresponding to each of the plurality of classes, and the code multiplexer includes a power controller that controls such that each of the plurality of classes are transmitted according, to the plurality of transmission power information sets.
