問題1

Which of the following carrier bandwidths does LTE support? (multiple choice)

A. 15M

B. 20M

C. 40M

D. 5M

正確答案: A,B,D

問題2

In mobile communication systems, there are usually two ways to define/obtain KPL: eNodeB performance statistics and drive test tools for drive test.

A. False

B. True

正確答案: B

問題3

The LTE system can only switch based on frequency priority.

A. False

B. True

正確答案: A

問題4

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 1dB

B. Cell reference signal power is reduced by 3dB

C. Cell reference signal power is increased by 3dcorrect

D. Cell reference signal power is increased by 1dB

正確答案: C

問題5

For the following LTE neighborhood planning, which description is correct? (Multiple choice)

A. The directly adjacent cell geographically is generally used as a neighboring area.
For dense urban areas and ordinary urban areas, due to the relatively short distance between stations (0.3~1.0 km), neighboring areas should do more

B. ANR function can completely replace the neighboring area planning of the initial network

C. Because there is no sequence problem in the neighboring area of LTE, and the detection period is very short, it is only necessary to consider not missing the neighboring cells without needing to sort the neighboring cells strictly according to the signal strength.

正確答案: A,B,C

問題6

The single-site verification test only needs to verify whether the cell status is normal in the idle mode.

A. False

B. True

正確答案: A

問題7

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

A. False

B. True

正確答案: B

問題8

Which of the following causes the interference in the system? (Multiple choice)

A. TDD ultra-long-distance interference (interference from DwFTS to UpPTS)

B. LTE TDD frame out of sync

C. Illegal use of LTE frequency bands

D. Interference caused by data configuration (time slot ratio, PCI, frequency)

正確答案: A,B,D

問題9

High-end commercial buildings, airports, large venues, large shopping malls, high-end residential communities and other large traffic and VIP scenarios are suitable for co-deployment of MIMO solutions. What are the advantages of this solution? (Multiple choice)

A. High capacity

B. Can fully reflect the MIMO uplink and downlink capacity gain

C. low cost

D. project Low difficulty

正確答案: A,B
