Detailed Description

Testing UE measurements in LTE with simulation of 1 eNodeB and 1 UE in piecewise configuration and 120 ms report interval.

During the simulation the placement of UE is being changed several times. Four different cases are considered: UE is very near to eNodeB, UE is near to eNodeB, UE is far from eNodeB and UE is very far from eNodeB. Test checks if the measurements correspond to the real conditions of the UE, i.e. when the signal from serving cell becomes weak, the measurements should also start to correspond to the new channel conditions. Additionally, it is checked if UE detects some neighboring signal, if it does the test fails because there is no neighbor in this configuration. Also, test checks if the reporting occurs at intervals that it should according to the measurements configuration. If it occurs in some different time stamp the test will fail.
