CHANNEL QUALITY INDICATION AND MODULATION AND CODING SCHEME NOTIFICATION METHOD AND DEVICE.

摘要

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