質問 # 13
Which of the following statements about link budget parameters is incorrect?
- A. The shadow fading margin is related to the edge coverage rate.
- B. The higher the edge service rate, the lower the required SINR demodulation threshold.
- C. The interference margin is relatively small on high frequency bands.
- D. The antenna gain of the 64T64R A All is approximately 24 dBi.
正解：B
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.

Which of the following protocol layers has been added to the 5G air interface protocol stack compared with
4G?
- A. MAC
- B. SDAP
- C. POCP
- D. RRC
正解：B
解説：
Explanation
According to the HCIA-5G V2.0 Exam Outline, SDAP is a new protocol layer added to the 5G air interface protocol stack compared with 4G. SDAP stands for Service Data Adaptation Protocol, and it is used to map QoS flows to data radio bearers and perform header compression and decompression.
質問 # 17
For a 60 kHz SCS configuration, how many time slots are included in a radio frame?
- A. 0
- B. 1
- C. 2
- D. 3
正解：A
解説：
For NR:
15 kHz → 10 slots/frame
30 kHz → 20 slots/frame
60 kHz → 40 slots/frame
120 kHz → 80 slots/frame
Thus, a 60 kHz SCS configuration contains 40 slots per radio frame.
質問 # 18
On a 5G network, the NAS layer uses 5G-GUTI to replace IMSI as the temporary ID of a UE for security reasons.
- A. True
- B. False
正解：A
解説：
Explanation
According to the 5G-GUTI - 5G Globally Unique Temporary Identity, the NAS layer uses 5G-GUTI to replace IMSI as the temporary ID of a UE for security reasons. The 5G-GUTI is allocated by the AMF (Core Access and Mobility Management Function) at the time of network registration, and it is composed of the GUAMI (Globally Unique AMF ID) and the 5G-TMSI (5G Temporary Mobile Subscriber Identity).
質問 # 19
In the window size, the larger the window, the stronger the resistance to delay.
- A. True
- B. False
正解：A
解説：
A larger transmission window can tolerate longer delays and larger round-trip times before throughput degradation occurs.
質問 # 20
In downlink peak rate testing, the modulation and coding scheme (MCS) index must reach 32.
- A. True
- B. False
正解：A
解説：
Explanation
According to the HCIA-5G V2.0 Exam Outline, in downlink peak rate testing, the modulation and coding scheme (MCS) index must reach 32, which corresponds to option A.
質問 # 21
For SA networking, voice solutions include VoNR and CSFB.
- A. True
- B. False
正解：B
解説：
CSFB (Circuit Switched Fallback) relies on LTE/3G legacy networks and is not an SA voice solution. SA voice is primarily supported through VoNR.
質問 # 22
In SA networking, the mobility between adjacent cells on the same frequency can use the redirection process.
- A. True
- B. False
正解：B
解説：
For intra-frequency mobility in SA networks, handover is the preferred mechanism. Redirection is typically used for fallback or idle-mode mobility rather than connected-mode same-frequency mobility.
質問 # 23

正解：B
解説：
When only the NR secondary cell group fails:
The UE reports SCG Failure Information.
The network may subsequently issue RRC Release depending on recovery procedures.
(This is a multiple-answer question.)

- A. PUSCH SINR
- B. PUSCH power spectral density
- C. PUSCH RSRP
- D. PUSCH BLER
正解：A

The gNB adjusts uplink transmit power primarily based on the received PUSCH SINR to maintain target uplink quality.
質問 # 25
In order to achieve ideal coverage, what is the clearance requirement around an antenna?
- A. 1-5m
- B. 5-10m
- C. 5000-10000m
- D. 50-100m
正解：B
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 # 26
Which of the following are common causes of overshoot coverage?(Select All that Apply)
- A. The height of the antenna or AAU is too low.
- B. Signals travel far along a street due to the waveguide effect.
- C. Reflection in a large amount of water.
- D. The transmit power of a base station is too high.
正解：B、C
解説：
Explanation
According to the HCIA-5G - Huawei Enterprise Support Community, reflection in a large amount of water and signals traveling far along a street due to the waveguide effect are common causes of overshoot coverage, which correspond to options A and C.
質問 # 27
During downlink scheduling, which of the following services has the highest scheduling priority?
- A. RRC signaling
- B. MIB
- C. SIB

MIB carries essential system information required for cell access. Therefore, its transmission has the highest scheduling priority.
質問 # 28
Which of the following SI messages must be read on a 5G network?
- A. SIB2
- B. SIB1
- C. SIB3
- D. SIB4
正解：B
解説：
Explanation
According to the 5G SIB Messages, SIB1 is the only mandatory SI message that must be read on a 5G network. SIB1 contains essential information for accessing the network, such as cell identity, cell barring, and scheduling information for other SI messages. SIB2, SIB3, and SIB4 are optional SI messages that provide additional information such as radio resource configuration, intra-frequency cell reselection, and neighboring cell information.
