Abstract
A method, an apparatus and an LTE terminal for determining a CQI value are provided and belongs to the field of mobile communications. The method for determining a CQI value includes that a terminal establishes a correspondence between an effective SNR threshold and a CQI value, the terminal acquires a mean effective SNR in a downlink subframe specified bandwidth, and the terminal determines, according to the acquired mean effective SNR and the correspondence, a CQI value to be sent to a base station. The technical scheme of the disclosure is applicable to various different frequency selective fading channels and different signal transmission modes and can be implemented in a low-complexity way.
