In the newly-built two-channel indoor sub-system, because LTE uses the MIMO feature, the uplink and downlink rate of the two-channel indoor sub-system is twice that of the single-channel indoor sub-system.

• A.False
• B.True

If the UE fails to switch, it is mostly characterized by dropped calls, RRC reestablishment, and so on.

• A.False
• B.True

Which of the following channel or signal is used to cell PCI identification and cell search process?

• A.PDCCH
• B.PCRCH
• C.PDSCH
• D.PSS/SSS

What are the principles that need to be followed when planning LTE neighboring cells? (Multiple choice)

• A.Turn on ANR to completely replace the neighborhood planning of the initial network
• B.For dense urban areas and ordinary urban areas, due to the relatively close distance between stations (0.3-1.0 km), neighbouring areas should do more
• C.Because there are no sequential I and possible questions in LTE neighboring cells, and the detection period is very short, it is only necessary to consider not missing neighboring cells, and it is not necessary to sort neighboring cells strictly according to signal strength.
• D.Neighborhoods that are directly adjacent to the geographic location are generally regarded as neighboring cells

Assuming other conditions are unchanged, if the power parameter PB is changed from 0 to 1, then which of the following statements is correct?

• A.Cell reference signal power is reduced by 3dB
• B.Cell reference signal power is increased by 3dcorrect
• C.Cell reference signal power is increased by 1dB
• D.Cell reference signal power is reduced by 1dB
