NEW QUESTION # 26
If AFGIobal is 15 kHz, FREF-Offs is 3000 MHz, and NREF-Offs is 600000, which of the following is the NR Absolute Radio Frequency Channel Number (NR-ARFCN) corresponding to 3300 MHz?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Explanation
According to the NR-ARFCN (NR absolute radio frequency channel number), the NR-ARFCN value consists of two components: the band indicator and the channel number. The band indicator represents the frequency band on which the carrier frequency lies, while the channel number represents the specific carrier frequency within that band. The NR-ARFCN value is calculated by the following formula:
NR-ARFCN = FREF-Offs + NREF-Offs + FGlobal * (Fcarrier - FREF-Offs) / AFGIobal where FREF-Offs is the reference frequency offset, NREF-Offs is the reference NR-ARFCN offset, FGlobal is the global frequency raster, Fcarrier is the carrier frequency, and AFGIobal is the absolute frequency granularity.
Given that AFGIobal is 15 kHz, FREF-Offs is 3000 MHz, and NREF-Offs is 600000, we can plug in these values and Fcarrier = 3300 MHz into the formula and get:
NR-ARFCN = 3000 + 600000 + 5 * (3300 - 3000) / 0.015 NR-ARFCN = 633000
Therefore, the correct answer is A.

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 # 29
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. Antenna gain
- C. Area coverage rate
- D. Shadow fading margin
Answer: A,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 # 32
In order to achieve ideal coverage, what is the clearance requirement around an antenna?
- A. 5000-10000m
- B. 5-10m
- C. 50-100m
- D. 1-5m
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 # 34
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 # 35
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 via backplane in a subrack
- B. Interconnection through HEI interfaces on the UBBP boards in different subracks
- C. Interconnection through CI interfaces on the UMPT boards in different subracks
- D. IPRAN interconnection between subracks
Answer: C,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.
