Ericsson Certified Associate - Radio Network Optimization Sample Questions:
1. A customer has Identified problems In an Indoor, medium loaded, urban area of a GSM/WCDMA collocated network. The problem seems to be in the uplink. The signal level received by the problematic site is high, and the downlink signal in the problematic area is acceptable.
Which two actions would you use to troubleshoot the issue? (Choose two.)
A) Run a passive inter-modulation (PIM) analysis.
B) Decrease base station transmission power.
C) Investigate external interference.
D) Add a pico cell In the same RAT and frequency.
2. 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) Reduce the hsPowerMargin parameter to make more power available for HSDPA.
D) Request or perform a build audit of the newly upgraded collocated WCDMA site.
3. Which statement describes uplink Discontinuous Transmission (DTX)?
A) DTX is a method of saving battery power for the BTS by turning off the transmitter while "voice" is not present.
B) DTX is a method of saving battery power for the MSC by turning off the transcoder while "voice" is not present.
C) DTX is a method of saving battery power for the MS by turning off the transmitter while "voice" is not present.
D) DTX is a method of saving battery power for the BSC by turning off the transcoder while "voice" is not present.
4. 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 provides a non defined link between subcarriers used in LTE and NR.
C) It maintains a more consistent overhead over a very large range of carrier frequencies.
D) It allows an alphanumeric mapping between physical data channels on coslted LTE and NR in non-standalone scenarios.
5. Which statement is correct about power control on an HS-PDSCH channel?
A) Inner closed loop power control is used.
B) Outer loop power control is used.
C) Available power for the EUL channel impacts the HS-PDSCH data capacity.
D) Available power and radio conditions impact the HS-PDSCH data rate.
