CQI variance Calculate the rate of CQI within Median CQI +/-2
It is calculated by the following equation.
(at the interim reporting)
• TTI
CQI variance = [CQI that is within +/-2 of the Median CQI from the beginning to the interim
reporting]/[CQI + DTX from the beginning to the interim reporting]
• CQI
CQI variance = [CQI that is within +/-2 of the Median CQI from the beginning to the interim
reporting]/[CQI from the beginning to the interim reporting]
(at the end of measurement)
• TTI
CQI variance = [CQI that is within +/-2 of the Median CQI during TTI period]/[CQI +DTX during
TTI period]
• CQI
CQI variance = [Median CQI within the reported number of CQI+/-2]/[reported number of CQI]
dian CQI within the reported number of CQI+/-2]/[reported number of CQI]
BLER Measures BLER.
It is calculated by the following equation.
BLER = ([NACK number] + [DTX number])/([ACK number] + [NACK number] + [DTX number])
The "number" implies the number from the beginning to the interim reporting at the interim
reporting, and the number of the entire measurement period at the end of the measurement.
