Which two statements about physical resource blocks (PRB)s are correct? (Choose two.)

A. The maximum number of assigned PRBs for a TTI can exceed the number of available PRBs in the cell for that TTI.

B. The DL PRB distribution is not affected by the number of active cell users in the cell.

C. A higher throughput is expected when more DL PRBs are assigned to a user for a TTI.

D. The number of PRBs assigned for a user is dependent on the number of active users in the 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 six dB.

D. The RSRP received by the UE is increased by three dB.

A. bearer drop rate

B. handover success rate

C. additional status total time for social media

D. initial buffering time for video

E. interactive time for Web browsing

Which two statements are valid for Call Re-establishment in WCDMA? (Choose two.)

A. Call Re-establishment in WCDMA targets RL failures or RLC errors in the DL.

B. When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE selects a new cell using the soft handover procedure.

C. Call Re-establishment in WCDMA improves the voice drop rate.

D. When Call Re-establishment in WCDMA is activated and after RL failure or an RLC unrecoverable error, the UE goes to idle mode.

You have collocated sectors In your 2G network on the GSM 900 and the DCS 1800 bands. Reviewing the network level traffic distribution, you noticed that the GSM 900 sectors have five times more traffic than the DCS 1800 sectors.

Which two actions would improve load balancing between these bands? (Choose two.)

A. adding additional GSM 900 sectors

B. changing the handover margin

C. expanding the site's transmission link

D. changing the idle mode cell reselection parameter

A customer is deploying VoLTE and complains about high voice drop rates and voice quality degradation at the cell edge in most LTE cells in the area. The network has a dense WCDMA coverage on the 700 MHz band and patchy LTE coverage on the 2100 MHz band.

Which two features would you activate to solve this problem? (Choose two.)

A. DRX

B. 256 QAM DL

C. TTI Bundling

D. SRVCC Handover to UTRAN
