FIELD: physics, communications.
SUBSTANCE: invention relates to communication and discloses a method and a device for notification with respect to a channel quality indicator and modulation and encoding schemes, which enable to select a modulation scheme higher than 64QAM for improving communication system efficiency. The method includes: emitting, 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 terminal UE; determining a first MCS index according to the first CQI table, the 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 the modulation order and the size of the code block according to the first MCS table and the received first MCS index; wherein 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.
EFFECT: high efficiency of the communication system.
