Disclosed are a method and device for notifying a channel quality indicator and a modulation and coding scheme, which relate to the field of communications, and can select a modulation mode which is higher than 64 QAM, thereby improving the performance of a communication system. The method comprises: a terminal learning a first CQI serial number according to a first CQI table, and sending the first CQI serial number to a base station; the base station receiving the first CQI serial number sent by a terminal UE, determining a first MCS serial number according to the first CQI table, a first MCS table and the received first CQI serial number, and sending the determined first MCS serial number to the UE; the terminal receiving the first MCS serial number sent by the base station, and determining a modulation order and the size of a coding block according to the first MCS table and the received first MCS serial number, wherein an item of which the modulation mode is higher than 64 QAM is included in the first CQI table, and an item of which the modulation mode is higher than 64 QAM is included in the first MCS table. |
