a) AvgCqiEfficiency_Cell.

b) The KPI describes the average air-interface efficiency for a NRCellDU according to CQI tables. The KPI takes into account both the channel rank(RI) and the channel quality(CQI), and can comprehensively reflect the overall channel quality of the cell. It is a real value. The unit of KPI refer to that of efficiency defined in TS 38.214. The KPI type is MEAN.

c) Below is the equation for average air-interface efficiency for NRCellDU:

Where is the efficiency used in the CQI table defined in TS 38.214 [14].

d) NRCellDU
