NEW QUESTION # 13
The UPEU in the BBU5900 needs to be connected to two circuit breakers.
- A. True
- B. False
Answer: B
Explanation:
Explanation
According to the BBU Quick Installation Guide (V100R005C10_04) (PDF)-EN, the UPEU in the BBU5900 needs to be connected to only one circuit breaker, not two. The UPEU is a universal power and environment interface unit that provides power supply and environment monitoring functions for other boards in a subrack.
The UPEU converts -48 V DC to +12 V DC and distributes the power to other boards. The UPEU also collects alarms from the subrack and reports them to the main processing board. The UPEU can be installed in slot 0 or slot 10 of the BBU5900 subrack. The UPEU needs to be connected to a -48 V DC power cable that is connected to a circuit breaker in the cabinet. The circuit breaker must have a rated current of 16 A or higher.
Therefore, the correct answer is B.

NEW QUESTION # 20
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

Answer: B,D
Explanation:
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.

NEW QUESTION # 27
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
Answer: A
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.

They reflect the utilization of physical resources in a cell.
NEW QUESTION # 30
In the cell search process in 5G SA, a UE completes frame synchronization after reading the SS.
- A. True
- B. False
Answer: B
Explanation:
Explanation
According to the 5G SA Cell Search & Network Entry Matrix, a UE completes frame synchronization after reading the MIB, not the SS. The SS (Synchronization Signal) is used for initial detection and coarse timing synchronization, but it does not provide enough information for frame synchronization. The MIB (Master Information Block) is part of the SSB (Synchronization Signal Block) and contains essential system information, such as system frame number and subcarrier spacing, which are needed for frame synchronization.
NEW QUESTION # 31
In SA networking, which of the following is the first step for a UE to perform a cell search?
- A. Synchronize frames and obtain PCI group number.
- B. Synchronize half-frames and obtain the ID within a PCI group.
- C. Obtain other cell information.
- D. Obtain the cell signal quality.
Answer: A
Explanation:
Explanation
According to the 5G SA Cell Search & Network Entry Matrix, the first step for a UE to perform a cell search in SA networking is to synchronize frames and obtain PCI group number. This step involves the following sub-steps:
The UE scans the available frequency range to detect the presence of Synchronization Signal Blocks (SSBs) from different base stations. SSBs are periodic signals that contain essential synchronization and system information for cell search and initial access.
The UE selects an SSB with the strongest signal strength and decodes its Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS). The PSS and SSS are part of the SSB and provide coarse timing synchronization and cell identity information.
The UE uses the PSS and SSS information to synchronize its internal clock with that of the base station and obtain the Physical Cell Identity (PCI) group number. The PCI group number is a 9-bit value that identifies a group of 8 cells that share the same PSS and SSS sequences. The PCI group number ranges from 0 to 1007.
The other steps for a UE to perform a cell search in SA networking are:
Synchronize half-frames and obtain the ID within a PCI group: The UE further synchronizes its timing with the base station by decoding its Narrowband Synchronization Signal (NSSS), which is also part of the SSB. The NSSS provides more precise timing information and the ID within a PCI group, which is a
3-bit value that identifies a specific cell within a PCI group. The ID within a PCI group ranges from 0 to
7. By combining the PCI group number and the ID within a PCI group, the UE can obtain the full PCI, which is a 10-bit value that uniquely identifies a cell.
Obtain other cell information: The UE decodes other signals and channels in the SSB to acquire other cell information, such as system bandwidth, subcarrier spacing, frame structure, etc. These signals and channels include Demodulation Reference Signals (DMRS), Master Information Block (MIB), System Information Block (SIB), etc.
Obtain the cell signal quality: The UE measures the cell signal quality based on various indicators, such as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal-to-Interference-plus-Noise Ratio (SINR), etc. These indicators reflect the strength, quality, and interference level of the received signal.
