LINE QUALITY REPORT ACCURACY MEASUREMENT DEVICE AND ACCURACY MEASUREMENT METHOD

摘要

A line quality report accuracy measurement device and accuracy measurement method capable of accurately measuring the accuracy of line quality reported from a communication device. A method control section (140) contains an encoding ratio corresponding to the CQI and a modulation method and specifies a transmission method corresponding to the fixed CQI reported from a CQI statistic processing section (230). A CQI decoding section (220) decodes a report CQI contained in the reception signal. The CQI statistic processing section (230) statistically processes the report CQI corresponding to the test data transmitted prior to an accuracy measurement test and notifies the CQI which has been reported most frequently as a fixed CQI to the method control section (140). A PER calculation section (260) calculates PER in the communication device according to the report CQI and Ack/Nack corresponding to the test data transmitted in accordance with the fixed CQI. A judgment section (270) performs a threshold value judgment for PER for each report CQI value and outputs the judgment result of the accuracy of the report CQI.
