FIELD: communication equipment.
SUBSTANCE: invention relates to communication. Method includes: examining by the terminal the first CQI index according to the first CQI table; sending the first CQI index to the base station; receiving of the first CQI index by the base station sent by the terminal UE; determining the first MCS index according to the first CQI table, the first MCS table, and the received first CQI index; sending a specific first MCS index to the UE; reception of the first MCS index by the terminal sent by the base station; and determining the modulation order and the code block size according to the first MCS table and the received first MCS index; the first CQI table includes records in which the modulation schemes are higher than 64QAM and the first MCS table includes records in which the modulation schemes are higher than 64QAM.
EFFECT: invention discloses a method and apparatus for notifying a channel quality indicator and a modulation and coding scheme, which allows to select a modulation scheme that is higher than 64QAM to improve the performance of the communication system.
