Explanation:
Explanation
According to the HCIA-5G - Huawei Enterprise Support Community, overlapping coverage is likely to occur in areas such as inside a tunnel, crossroads in dense urban areas, and high-rise buildings, which correspond to options A, B, and C. These areas have complex propagation environments and multiple paths for signals to reach the UE. Around areas with water, overlapping coverage is unlikely to occur because water can reflect signals and reduce interference from other cells, which corresponds to option D.
NEW QUESTION # 19
Which of the following SI messages must be read on a 5G network?
- A. SIB2
- B. SIB1
- C. SIB4
- D. SIB3
Answer: B
Explanation:
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.
NEW QUESTION # 20
What are characteristics of eCPRI links? (Select All that Apply)
- A. They are based on the IP mechanism.
- B. They are based on the TDM mechanism.
- C. They require dock synchronization.
- D. They require AAU support.
Answer: A,C,D
Explanation:
They require clock synchronization: eCPRI links use Ethernet as the transport layer, which does not provide inherent synchronization. Therefore, eCPRI links require external clock synchronization methods, such as IEEE 1588v2 Precision Time Protocol (PTP) or Synchronous Ethernet (SyncE).
They are based on the IP mechanism: eCPRI links use IP as the network layer, which provides routing and addressing functions for eCPRI messages. eCPRI links can use either IPv4 or IPv6 protocols.
They require AAU support: eCPRI links connect between Radio Equipment Control (REC) and Radio Equipment (RE) in a base station. AAU (Active Antenna Unit) is a type of RE that integrates RF and antenna functions in one unit. Therefore, eCPRI links require AAU support to enable flexible functional split options and reduce fronthaul bandwidth requirements.
eCPRI links are not based on the TDM mechanism because they do not use fixed time slots to transmit data. Instead, they use variable-length packets to transmit data according to different service requirements.

NEW QUESTION # 26
Which of the following statistics are provided by the Probe's BLER statistics menu?(Select All that Apply)
- A. DIBLER
- B. DRBLER
- C. Modulation scheme
- D. Retransmission ratio
Answer: A,B,D
Explanation:
Explanation
According to the Probe User Guide (V100R019C10_01) (PDF)-EN, the Probe's BLER statistics menu provides the following statistics:
DIBLER: Downlink Initial Block Error Rate, which is the ratio of the number of erroneous downlink transport blocks to the total number of downlink transport blocks received by the UE in the first transmission.
DRBLER: Downlink Residual Block Error Rate, which is the ratio of the number of erroneous downlink transport blocks to the total number of downlink transport blocks received by the UE after all retransmissions.
Retransmission ratio: The ratio of the number of retransmitted downlink transport blocks to the total number of downlink transport blocks received by the UE.
The Probe's BLER statistics menu does not provide the modulation scheme as a statistic. The modulation scheme is a parameter that determines the modulation and coding scheme (MCS) used for data transmission on the physical downlink shared channel (PDSCH). The modulation scheme can be QPSK, 16QAM, 64QAM, or
256QAM. The modulation scheme can be displayed on the Probe's PDSCH configuration menu or PDSCH demodulation menu.
Therefore, the correct answer is A, B, and D.

NEW QUESTION # 30
In order to achieve ideal coverage, what is the clearance requirement around an antenna?
- A. 50-100m
- B. 5000-10000m
- C. 1-5m
- D. 5-10m
Answer: D
Explanation:
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.
NEW QUESTION # 31
Which of the following items can be used for measurement evaluation in idle mode during coverage problem analysis?
- A. SS-RSRP
- B. SRS
- C. CSI-RSRP

Explanation:
According to the HCIA-5G V2.0 Exam Outline , SS-RSRP is the reference signal received power of the synchronization signal block (SSB) in NR systems. It can be used for measurement evaluation in idle mode during coverage problem analysis, which corresponds to option D. OPMI is an indicator of uplink interference power measurement, CSI-RSRP is the reference signal received power of the channel state information reference signal (CSI-RS), and SRS is the sounding reference signal. These indicators are used for measurement evaluation in connected mode, not idle mode, which correspond to options A, B, and C.

NEW QUESTION # 34
Which of the following is not a typical application scenario of massive MIMO?
- A. Densely populated urban areas
- B. High-rise buildings
- C. Large venues
- D. Suburban areas with light traffic
Answer: D
Explanation:
Explanation
Massive MIMO is a technology that uses a large number of antennas at the base station to serve multiple users simultaneously, thereby increasing the spectral efficiency and capacity of the wireless system 1. Massive MIMO is especially suitable for application scenarios where there is high user density and high traffic demand, such as large venues, high-rise buildings, and densely populated urban areas 2. Suburban areas with light traffic do not have such high requirements for spectral efficiency and capacity, and therefore are not a typical application scenario of massive MIMO.

Which of the following AAUs support vertical beamforming?(Select All that Apply)
- A. 64T64R
- B. 32T32R
- C. 4T4R
- D. 8T8R
Answer: A,B
Explanation:
Explanation

- B. Engineering file
- C. Site survey table
- D. Local map
Answer: B
Explanation:
According to the 5G Site Survey Guide (V1.0) (PDF)-EN , the engineering file is not a material that needs to be prepared before site survey. The engineering file is a document that records the site survey results and the design plan for the site. The engineering file is generated after the site survey is completed and approved by the customer. The materials that need to be prepared before site survey are:
Local map: A map of the area where the site is located, showing the roads, buildings, landmarks, and other features. The local map helps the site survey team to plan the route, identify the site location, and evaluate the surrounding environment.
Site survey table: A table that lists the items and parameters that need to be checked and measured during the site survey, such as antenna installation space, equipment room space and load bearing capacity, power supply, grounding, lightning protection, cable routing, etc. The site survey table helps the site survey team to conduct a comprehensive and systematic inspection of the site conditions and record the data.
5G antenna height table: A table that shows the recommended antenna height for different scenarios and frequency bands based on empirical data and theoretical calculations. The 5G antenna height table helps the site survey team to determine the optimal antenna installation height for achieving the best coverage and performance.
