Performance Management Statistics have recently shown a sharp rise in received interference power on an LTE site during the busiest hours. A collocated WCDMA base station has recently acquired a new carrier and upgraded power amplifier. The upgrade correlates with the sharp rise in received interference power.
What are two appropriate actions to solve this problem? (Choose two.)

• A.Increase the power amplifier on the impacted collocated LTE sectors.
• B.Review the site design in consultation with the Ericsson collocation and coexistence guidelines.
• C.Request or perform a build audit of the newly upgraded collocated WCDMA site.
• D.Reduce the hsPowerMargin parameter to make more power available for HSDPA.

Which two statements are true about the Antenna Integrated Radio (AIR)? (Choose two.)

• A.The AIR can replace the standard RU/RRU and antenna.
• B.The AIR is a hardware unit that integrates the radio and the antenna.
• C.The AIR replaces the digital/baseband unit.
• D.The AIR in an LTE system is directly connected with the MME using the SI interface.

Which two statements correctly describe Single Carrier Frequency Division Multiple Access (SC-FDMA) as used in LTE systems using uplink SIMO? (Choose two.)

• A.SC-FDMA separates uplink transmissions in the time and/or frequency domain.
• B.SC-FDMA allows simultaneous uplink transmissions on the same physical resource blocks.
• C.SC-FDMA is beneficial because it avoids (nter-cell interference.
• D.SC-FDMA is beneficial because it avoids intra-cell interference.

What is an advantage of using flexible numerology in New Radio (NR) 5G?

• A.It ensures that the same subcarrier bandwidth is used in NR in both high and low frequencies.
• B.It maintains a more consistent overhead over a very large range of carrier frequencies.
• C.It provides a non defined link between subcarriers used in LTE and NR.
• D.It allows an alphanumeric mapping between physical data channels on coslted LTE and NR in non-standalone scenarios.

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