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.
Therefore, the correct answer is D.

PLMN configurations are incorrect: If the PLMN configurations on the base station and the core network do not match, the SCTP link cannot be established or may be disconnected.
Physical ports are faulty: If the physical ports on the base station or the core network are faulty, such as damaged cables, loose connectors, or port errors, the SCTP link cannot be established or may be disconnected.
The SCTP port configuration is incorrect: If the SCTP port configuration on the base station or the core network is incorrect, such as using a reserved port number or a conflicting port number, the SCTP link cannot be established or may be disconnected.

NEW QUESTION # 25
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.

NEW QUESTION # 26
How many RBs are included when a bandwidth of 100 MHz and a subcarrier spacing of 60 kHz are used in a
5G cell?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: A

Explanation:
Explanation
To find the number of RBs in a 5G cell, we need to know the bandwidth and the subcarrier spacing of the cell.
The bandwidth is the total frequency range allocated for the cell, while the subcarrier spacing is the frequency separation between adjacent subcarriers in the cell. A RB is a group of 12 consecutive subcarriers in the frequency domain 12. Therefore, the number of RBs in a 5G cell can be calculated by dividing the bandwidth by the product of the subcarrier spacing and 12.
Given that the bandwidth is 100 MHz and the subcarrier spacing is 60 kHz, we can use the following formula to find the number of RBs:
Number of RBs = Bandwidth / (Subcarrier spacing * 12) Number of RBs = 100 MHz / (60 kHz * 12) Number of RBs = 100000 kHz / 720 kHz Number of RBs = 138.888...
However, since the number of RBs must be an integer, we need to round it down to the nearest multiple of
3 3. This is because the NR standard defines different frequency ranges for different subcarrier spacings, and each frequency range has a minimum and maximum number of RBs that are multiples of 3 4. For example, for subcarrier spacing of 60 kHz, the frequency range is from 24250.08 MHz to 52600.08 MHz, and the minimum and maximum number of RBs are 66 and 273, respectively.
Therefore, the closest multiple of 3 to 138.888... is 135. However, this number is not valid because it is lower than the minimum number of RBs for subcarrier spacing of 60 kHz. The next valid multiple of 3 is 273, which is also the maximum number of RBs for subcarrier spacing of 60 kHz. Therefore, the correct answer is C. 273.

NEW QUESTION # 28
In the MR-DC architecture, which of the following factors affect the data split on a base station?(Select All that Apply)

• A. Air interface latency
• B. RLC layer buffer
• C. X2 latency
• D. PDCP layer buffer

Answer: A,C,D

Explanation:
Explanation
According to the 5G-NR (EN-DC) Bearer Concept, in MR-DC (Multi-Radio Dual Connectivity) architecture, data split on a base station can be affected by the following factors:
PDCP layer buffer: The PDCP layer buffer stores user plane data before sending it to lower layers. The buffer size and occupancy can affect how data is split between LTE and NR bearers.
X2 latency: The X2 latency is the delay between LTE and NR base stations over the X2 interface. The X2 latency can affect how data is split between LTE and NR bearers by causing reordering or duplication of packets.
Air interface latency: The air interface latency is the delay between base stations and user equipment over the air interface. The air interface latency can affect how data is split between LTE and NR bearers by causing reordering or duplication of packets.
The RLC layer buffer does not affect data split on a base station because it is located below the PDCP layer where data split occurs.
