NEW QUESTION # 23
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
Answer: B
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 # 24
In an intra-frequency reselection procedure, which message contains the rangeToBestCell parameter?

Explanation:
Explanation
According to the 38.331 RRC, SIB2 is the message that contains the rangeToBestCell parameter, which is used for intra-frequency cell reselection. The rangeToBestCell parameter defines a threshold for cell ranking based on RSRP (Reference Signal Received Power). A UE may only reselect to a cell if its RSRP exceeds that of the serving cell by at least rangeToBestCell dB.
NEW QUESTION # 25
In the MR-DC architecture, which of the following factors affect the data split on a base station?(Select All that Apply)
- A. X2 latency
- B. Air interface latency
- C. PDCP layer buffer
- D. RLC layer buffer
Answer: A,B,C
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.

NEW QUESTION # 27
Under the same gNodeB, an NR TDD cell supports the same maximum number of RRC_CONNECTED UEs as an NR FDD cell.
- A. True
- B. False
Answer: B
Explanation:
Explanation
According to the Radio Resource Control, the maximum number of RRC_CONNECTED UEs depends on the number of available C-RNTIs (Cell Radio Network Temporary Identifiers) in a cell. The number of C-RNTIs is limited by the size of the RNTI field in the DCI (Downlink Control Information) format. For NR TDD cells, the RNTI field size is 16 bits, which allows up to 65,536 C-RNTIs. For NR FDD cells, the RNTI field size is
14 bits, which allows up to 16,384 C-RNTIs. Therefore, an NR TDD cell can support more RRC_CONNECTED UEs than an NR FDD cell under the same gNodeB.
NEW QUESTION # 28
Which of the following factors does not need to be considered during PUSCH power calculation?
- A. Number of PUSCH RBs
- B. SCS configuration for the PUSCH
- C. Number of PUSCH symbols in the time domain
- D. MCS index of the PUSCH
Answer: D
Explanation:
Explanation
According to the 5G NR Uplink Power Control Procedure, MCS index of the PUSCH is not a factor that needs to be considered during PUSCH power calculation. The MCS index determines the modulation and coding scheme of the PUSCH, but it does not affect the transmit power. The other factors, such as number of PUSCH RBs, SCS configuration for the PUSCH, and number of PUSCH symbols in the time domain, are all involved in the PUSCH power calculation formula.

Which of the following is not a typical application scenario of massive MIMO?
- A. Large venues
- B. Suburban areas with light traffic
- C. Densely populated urban areas
- D. High-rise buildings
Answer: B
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.
NEW QUESTION # 39
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: C
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 # 40
In cases where the same devices are used, which of the following link budget parameters may differ depending on use in either densely populated urban areas or rural areas?(Select All that Apply)
- A. Penetration loss
- B. Shadow fading margin
- C. Area coverage rate
- D. Antenna gain
Answer: A,B,C
Explanation:
Explanation
The link budget parameters that may differ depending on use in either densely populated urban areas or rural areas are area coverage rate, shadow fading margin, and penetration loss. The area coverage rate is the percentage of area within a cell that can receive a signal above a certain threshold. In densely populated urban areas, the area coverage rate may be lower than in rural areas due to more interference and obstacles 13. The shadow fading margin is an additional margin added to the link budget to account for the variation of signal strength due to obstacles in the propagation path. In densely populated urban areas, there may be more buildings and structures that cause shadow fading than in rural areas, so a larger shadow fading margin may be needed 14. The penetration loss is the loss of signal strength when it passes through walls or windows into buildings. In densely populated urban areas, there may be more indoor users than in rural areas, so a larger penetration loss may be considered 15. The antenna gain is not a parameter that depends on use in either densely populated urban areas or rural areas. It is a parameter that depends on the antenna design and configuration, which are usually fixed for a given system 16.
