Some questions from ETCP:
not too difficult...
How many resource blocks are available in an LTE with 10Mhz
What is the objective of the downlink power control in WCDMA nw
when is softer HO executed
A TMA is deployed on a rural LTE RBS and improves Ul sensitivity by 2dB. No interference. What is the SINR improvement?
What are two primary goals for GSM traffic load balancing
New residental area is buildt showing a lack of coverage, 20m buildings, flat terrain. What should be applied to cells A_1 and B_1, SHO=1.9
how would you assign the maximum power per radio link
Performance Man Stat has shown sharp raise in inerference on LTE site during BH. A clocated 3G site has new carrier and upgraded power amplifier. Actions(2)
regarding LTE what does the term "inter-frequency load sharing" mean?
Optimization using OSS counters vs drive test provides which 2 benefits
during a GSM dt call drops occur in areas with good coverage. What do you review in test results to determine the reason?
what are two inputs for monitoring and troubleshooting tools?
What is the purpose of Radio Resource Managment parameter optimization tools?
what is the benefit of Self Org Network solution?
Why is a traffic balancing done in WCDMA
Soft congestion in WCDMA means
RRM Cell Level Parameter Optimiztion enables
What does ANR in WCDMA use as an input?
Indoor problem, GSM and WCDMA are co-located. Good signal level, poor quality. What should you investigate
Good signal, poor 2x2 MIMO usage in LTE. How could that happen
What is the benefit of Direct Packet Transfer feature in LTE
For non HS (DCH) traffic balancing, what condition should be satisfie
What is done by BSC?
LTE Uplink uses SC-FDMA. What is true
Dense urban, 2 location areas on the highway, there is high signaling congestion. In addition to changing LA plan, what to do?
There is a chart with RWTP during 24 hours. It is higher during the busy hours. In drive test several IRAT Handovers were spotted due to interference, although the coverage is good. What happened?
UL sensitivity is improved through Rx Diversity. Why (choose two
There are thee combinations RTT (Round Trip Time) and RSRP. Conclusion is that RTT time is higher when radio conditions are worse. Why is that so
How is HS-PDSCH power controlled
