質問 # 13
In order to achieve ideal coverage, what is the clearance requirement around an antenna?
- A. 5-10m
- B. 50-100m
- C. 1-5m
- D. 5000-10000m
正解：A
解説：
Explanation
In order to achieve ideal coverage, there should be a clearance zone around an antenna of at least d, where d is the Fraunhofer or Rayleigh distance at which the near/far-field transition zone exists 17. This distance depends on the largest dimension of the antenna, D, and the operating wavelength, \uF06C. Ideally, D should be at least a half of a wavelength, which gives a minimum clearance zone of a half-wavelength. For example, at 2.4 GHz, the wavelength is about 0.125 m, so the minimum clearance zone is about 0.0625 m. However, in practical situations, this clearance zone is often compromised and the effects must be determined through simulation or empirical measurement 18. A general guideline is to have a clearance zone of 5-10 m around an antenna to avoid significant degradation of performance 19. Therefore, the best answer is C.
質問 # 14
In NSA networking, which of the following methods can be used to support X2 interconnection between an eNodeB and a gNodeB?(Select All that Apply)
- A. Interconnection through HEI interfaces on the UBBP boards in different subracks
- B. Interconnection through CI interfaces on the UMPT boards in different subracks
- C. Interconnection via backplane in a subrack
- D. IPRAN interconnection between subracks
正解：B、D
解説：
Explanation
According to the 5G EN-DC Architecture and Interfaces, there are two methods that can be used to support X2 interconnection between an eNodeB and a gNodeB in NSA networking:
Interconnection through CI interfaces on the UMPT boards in different subracks: The UMPT is a universal main processing and transmission unit that provides main processing and transmission functions for a subrack. The UMPT has two CI interfaces that can be used for X2 interconnection with other base stations. The CI interfaces support CPRI, OBSAI, and eCPRI protocols and can use optical fibers or electrical cables for transmission. The CI interfaces can be configured as master or slave interfaces depending on the network topology.
IPRAN interconnection between subracks: IPRAN is an IP-based radio access network that uses IP transport technologies to carry base station traffic over Ethernet or MPLS networks. IPRAN can support X2 interconnection betweendifferent base stations by using IP routers or switches. IPRAN can provide flexible networking, high bandwidth, low latency, and high reliability for X2 interconnection.
The other two methods are not valid for X2 interconnection between an eNodeB and a gNodeB:
Interconnection via backplane in a subrack: This method is only applicable for X2 interconnection between two eNodeBs or two gNodeBs that are installed in the same subrack. The backplane is the internal bus that connects different boards within a subrack. The backplane supports CPRI, OBSAI, and eCPRI protocols and can provide high-speed data transmission between boards.
Interconnection through HEI interfaces on the UBBP boards in different subracks: This method is not supported by Huawei base stations. The HEI interface is a high-speed Ethernet interface that is used for data transmission between base stations and core networks or transport networks. The HEI interface supports S1, Xn, F1, E1, and N2 protocols and can use optical fibers or electrical cables for transmission. The HEI interface cannot be used for X2 interconnection between base stations.
Therefore, the correct answer is A and D.

質問 # 30
Which of the following statements about link budget parameters is incorrect?
- A. The interference margin is relatively small on high frequency bands.
- B. The shadow fading margin is related to the edge coverage rate.
- C. The higher the edge service rate, the lower the required SINR demodulation threshold.
- D. The antenna gain of the 64T64R A All is approximately 24 dBi.
正解：C
解説：
Explanation
A link budget is an accounting of all the power gains and losses that a communication signal experiences in a telecommunication system 8. A link budget can be used to determine the received signal-to-interference-plus-noise ratio (SINR), which is a measure of the quality of the signal at the receiver.
The SINR demodulation threshold is the minimum SINR required to demodulate the signal successfully. The SINR demodulation threshold depends on the modulation and coding scheme (MCS) used by the transmitter, which in turn depends on the service rate or data rate required by the application 9. Generally, the higher the service rate, the higher the MCS level, and therefore the higher the SINR demodulation threshold. Thus, statement A is incorrect. The other statements are correct. The interference margin is relatively small on high frequency bands because there are fewer co-channel interferers due to smaller cell sizes 10. The shadow fading margin is related to the edge coverage rate because it accounts for the variation of signal strength due to obstacles in the propagation path 11. The antenna gain of the 64T64R AAU is approximately 24 dBi according to Huawei's product specifications 12.
