Abstract

Embodiments of the present disclosure provide a method and apparatus for configuring channel quality indicator (CQI) and a method and apparatus for configuring modulation and coding scheme. The method for configuring CQI includes: configuring UE with a CQI index table by an eNB via CQI index table indication information, so that the UE determines the configured CQI index table according to the indication information, and calculates a CQI index according to calculated precoding matrix indicator (PMI) and rank indication (RI) by using the configured CQI index table. With the embodiments of the present disclosure, the eNB may configure different UEs with different '4-bit CQI tables' and/or 'modulation and TBS index tables' while keeping the CQI index and the Ibit number unchanged. Therefore, not only the CQI index and the Ibit number need not to be increased, but also normal configuration of the LTE system may be ensured.
