Provided in the embodiments of the present invention are a Channel Quality Indicator (CQI) configuration method and Modulation and Coding Scheme configuration method and apparatus. The CQI configuration method comprises: a base station (eNB) uses CQI index table instruction information to configure a CQI index table for a UE; the UE determines the configured CQI index table on the basis of the instruction information, and, using the configured CQI index table, calculates the CQI index on the basis of the calculated Precoding Matrix Indicator (PMI) and Rank Indication (RI). The present embodiments allow a base station, under the precondition that the CQI index and IMCS bit numbers remain unchanged, to configure a different '4-bit CQI table' and/or 'modulation and TBS number table' for different UEs. Therefore, CQI index and IMCS bit numbers need not be increased and normal configuration of the LTE system may be ensured. |
