Method and apparatus for generating control information in wireless communication system

A method for generating control information by a base station in a wireless communication system, the method comprising:

• determining a first modulation and coding scheme (MCS) table based on a channel status,
• wherein the first MCS table is generated by removing a plurality of MCS entries related to a low-order modulation scheme from a second MCS table, and setting a last MCS table index as a retransmission mode for a high-order modulation scheme.

An apparatus for generating control information in a terminal for a wireless communication system, the apparatus comprising:

• a controller configured to determine whether the terminal supports a high-order modulation scheme, and to, if the terminal supports the high-order modulation scheme, feed back control information for supporting the high-order modulation scheme to a base station,
• wherein the control information includes a first channel quality indicator (CQI) table for supporting the high-order modulation scheme, and
• wherein the first CQI table is generated by removing a plurality of CQI entries from a second CQI table including a low-order modulation scheme and replacing a last CQI table index as the high-order modulation scheme.
