CQI is utilized by the versatile to demonstrate the channel quality to the eNB. The CQI range is between 0 and 15. This demonstrates the degree of modulation and coding the UE could work. CQI is an indicator conveying the data on communication channel quality. CQI is the data that UE transmit to the network and essentially it infers the two
i) Show the status of Current Communication Channel Quality.
ii) show the value transport block size of UE needs to get the information, which in turn can be directly changed over into throughput.
