摘要： When the diversity reception is cut, communications with the base station are continued. When it is judged by the judgment section of the mobile communication terminal that a predetermined disconnection requirement for disconnecting diversity reception is satisfied, the gain control section of the digital baseband circuitry 20 reduces the gain of the AGC14B contained in the RF receiver circuitry 10B constituting the disconnection target by a fixed value at fixed times. Diversity reception is cut after the level of the signal output by the AGC14B has reached zero.

摘要： 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.
