The present invention discloses a notification method and apparatus for a channel quality indicator and a modulation and coding scheme and relates to the field of communications, which can select a modulation scheme higher than 64QAM, so as to improve performance of a communications system. The method includes: learning, by a terminal, a first CQI index according to a first CQI table; sending the first CQI index to a base station; receiving, by the base station, the first CQI index sent by the terminal UE; determining a first MCS index according to the first CQI table, a first MCS table, and the received first CQI index; sending the determined first MCS index to the UE; receiving, by the terminal, the first MCS index sent by the base station; and determining a modulation order and a code block size according to the first MCS table and the received first MCS index; where the first CQI table includes entries in which modulation schemes are higher than 64QAM, and the first MCS table includes entries in which modulation schemes are higher than 64QAM. |
