Being the precision test equipment which tests the precision of report value of the circuit

摘要

A channel quality report accuracy measurement apparatus and accuracy measurement method are provided that correctly measure the accuracy of channel quality reported from a communication apparatus. A scheme control section (140) stores coding rates and modulation schemes corresponding to CQIs, and specifies the transmission scheme corresponding to a fixed CQI reported from a CQI statistical processing section (230). A CQI decoding section (220) decodes a reported CQI contained in a received signal. The CQI statistical processing section (230) performs statistical processing of reported CQIs corresponding to test data transmitted prior to an accuracy measurement test, and reports the most frequently reported CQI to the scheme control section (140) as a fixed CQI. A PER calculation section (260) calculates the PER in the communication apparatus from the reported CQI and Ack/Nack corresponding to test data transmitted in accordance with the fixed CQI. A determination section (270) performs threshold value determination for the PER for each reported CQI value, and outputs the reported CQI scheme determination result. IMAGE
