An LTE operator explains that the traffic in cell A is very high compared to the traffic In cell B, which are close to each other. Cells A and B are using the same frequency.
In this scenario, which two actions would balance the traffic between cell A and cell B? (Choose two.)

• A.Activate the inter-frequency load balancing feature.
• B.Activate the TTI Bundling feature.
• C.Optimize the idle mode related parameters.
• D.Optimize the connected mode mobility parameters.

What is a cause of degradation in the RSRQ of a serving cell?

• A.average power transmitted by the UE
• B.thermal noise
• C.SIB transmissions sent by the UE
• D.periodic measurement report transmissions in the serving cell

After an optimization meeting, an operator decides to double the transmitted power of an LTE cell. To test the effect of this change, a static test is performed before and after the change.
Which statement is correct in this scenario?

• A.The RSRP received by the UE remains stable.
• B.The variation of the RSRP will depend on the bandwidth of the cell.
• C.The RSRP received by the UE is increased by three dB.
• D.The RSRP received by the UE is increased by six dB.

In LTE, what is the definition of an A2 event?

• A.The neighbor cell becomes better than the threshold.
• B.The serving ceil becomes better than the threshold.
• C.The neighbor cell becomes worse than the threshold.
• D.The serving cell becomes worse than the threshold.

Which two statements about the Radio Connection Supervision (RCS) algorithm in LTE are correct? (Choose two.)

• A.It collects radio problems and inactivity information with the purpose to release resources.
• B.It controls the modulation and coding scheme used in DL transmissions.
• C.It supervises the radio connection between E-UTRAN and a UE in connected mode.
• D.It selects the number of PRBs assigned to users for downlink and uplink.
