the item 3 is the RXLEV below which there is a HO due to DL/UL signal strength ?
And above this value, it is considered as a interference HO if the RxQual is above 6, is it ?
The item 3 is set quite high, normally you should have -93dBm for DL and -103dBm in UL. So perhaps those thresholds overlap with your Power Control’s parameters ? What are the lower thresholds of UL and DL PC ?
