method and apparatus for setting up channel quality indicator and method and apparatus for setting up modulation and coding scheme

摘要

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 eu with a cqi index table by an enb via cqi index table indication information, so that the eu 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 imcs bit number unchanged. therefore, not only the cqi index and the imcs bit number need not to be increased, but also normal configuration of the lte system may be ensured. Abstract Method and Apparatus for Configuring Channel Quality Indicator and Method and Apparatus for Configuring Modulation and Encoding Scheme. The embodiments of the present disclosure provide a method and apparatus for configuring the channel quality indicator (cqi) and a method and apparatus for configuring the modulation and coding scheme. The method for configuring cqi includes: configuring the eu with a cqi index table by one enb through cqi index table indication information, so that u determines the cqi index table configured according to the information and calculate a cqi index according to a calculated precoding matrix indicator (pmi) and a rating indication (ri) using the configured cqi index table. With the embodiments of the present description, enb can configure different actions with different '4-bit cqi tables' and / or 'tbs index and modulation tables' while keeping the cqi index and the number of imcs bits unchanged. Therefore, not only the cqi index and the number of imcs bits need not be increased, but also a normal lte system configuration can be ensured.
