問題6

Review the exhibit.

An operator's LTE single layer network has a cell not carrying enough traffic. To increase the traffic carried by the cell, the operator decides to modify the Idle mode behavior of the cell. Values for the qRxLevMin and qQuaimin parameters are currently set to -120 dBm and -12 dB.
Referring to the exhibit, which two configurations would be used to potentially increase the traffic carried by this cell? (Choose two.)

A. Set the qQuaiMin parameter to -9 dB.

B. Set the qRxLevMin parameter to -123 dBm.

C. Set the qQualMin parameter to -15 dB.

D. Set the qRxLevMin parameter to -117 dBm.

正確答案: B,C
