NEW QUESTION # 38
Which of the following statements about the advantages of the Rayce ray tracing model are correct?(Select All that Apply)
- A. It is applicable only to C-band, and not mmWave.
- B. It offers higher level prediction accuracy.
- C. It offers more accurate modeling for massive MIMO.
- D. It offers more accurate path searching, reflection, and diffraction energy calculation for electromagnetic wave propagation.
Answer: B,D
Explanation:
Explanation
The Rayce ray tracing model is a propagation model that computes propagation paths using 3-D environment geometry 3. It is based on the shooting and bouncing rays (SBR) method, which launches rays from the transmitter and traces their reflections and diffractions until they reach the receiver or are attenuated below a threshold 4. The Rayce ray tracing model offers more accurate path searching, reflection, and diffraction energy calculation for electromagnetic wave propagation than other models, such as empirical models or deterministic models 5. It also offers higher level prediction accuracy, especially for massive MIMO systems that use beamforming techniques 6. The Rayce ray tracing model is not applicable only to C-band, but also to mmWave and other frequency bands 7.
NEW QUESTION # 39
In the existing network, we recommend that all cells use the configuration parameters under the peak rate scenario to improve user experience.

NEW QUESTION # 40
Which of the following factors does not need to be considered during PUSCH power calculation?
- A. Number of PUSCH RBs
- B. Number of PUSCH symbols in the time domain
- C. MCS index of the PUSCH
- D. SCS configuration for the PUSCH
Answer: C
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.
NEW QUESTION # 41

Link adaptation aims to maintain a target BLER. Therefore, MCS adjustments are primarily based on the observed PDSCH BLER performance.
NEW QUESTION # 42
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. Antenna gain
- B. Area coverage rate
- C. Shadow fading margin
- D. Penetration loss
Answer: B,C,D
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.

NEW QUESTION # 56
In the SIB1 message, if the expected preamble power is -100 dBm, the SSB transmit power is 18 dBm, and the current RSRP is -90 dBm, what is the preamble transmit power of the first PRACH of the terminal?
- A. -108 dBm
- B. 10 dBm
- C. -118 dBm
- D. 8 dBm
Answer: D
Explanation:
The initial PRACH preamble power is calculated as:
Preamble Power = PreambleReceivedTargetPower + Path Loss
Path Loss = SSB Tx Power - RSRP
= 18 - (-90) = 108 dB
Preamble Power = -100 + 108 = 8 dBm
