RRC Connection Reconfiguration for Measuring the Second Cell
To make it sure that Network triggers adding the second cell only when UE can detect the second cell with a certain signal condition, Network usually perform measurement for the second cell. One of the example of this measurement process is as follows.
According to 36.331,
ThresholdEUTRA For RSRP: RSRP based threshold for event evaluation. The actual value is IE value . 140 dBm. For RSRQ: RSRQ based threshold for event evaluation. The actual value is (IE value . 40)/2 dB. EUTRAN configures the same threshold quantity for all the thresholds of an event.
