Line quality report accuracy measurement device and accuracy measurement method

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.
