CQI has no unit.

A value of 15 indicates excellent quality, while 1 represents very poor quality.

Yes, CQI is an index.

Hi, I understand, but I’m specifically referring to the Huawei trace file.

I’m talking about the last item in this picture, which appears in the internal 5G NSA message.

It appears to be CQI reported with a value of 12.
