A communication terminal device and a reception environment reporting method produce a more excellent throughput, by making a report of a reception environment with higher accuracy. An SIR measuring section measures an SIR from a reception signal that has been received from a base transceiver station. A CQI converter converts the SIR that has been measured by the SIR measuring section into a CQI value. A BLER calculating section calculates a block error rate of the reception signal. A CQI correcting section corrects the CQI value that has been calculated by the CQI converter, in accordance with the block error rate. A CQI transmitter transmits the CQI value that has been corrected by the CQI correcting section, to the base transceiver station.
