質問 # 19
If multiple IP addresses with different next hop addresses are planned for the gNodeB, which of the following route configuration modes is not applicable?
- A. Destination address route configuration
- B. Source address route configuration
- C. Direct route configuration
正解：A
解説：
The destination address route configuration is not applicable when multiple IP addresses with different next hop addresses are planned for the gNodeB. Destination address route configuration is used when a single IP address is used by the gNodeB and the next hop address and outgoing interface do not need to be configured. In the case of multiple IP addresses with different next hop addresses, direct route configuration should be used. Direct route configuration requires that the IP address, next hop address, and outgoing interface all be specified for each IP address.

As defined in 3GPP, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR, reducing Interference under light loads and control channel overhead.
- A. True
- B. False
正解：A
解説：
the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR to reduce interference under light loads and control channel overhead. Instead, NR uses dynamic scheduling of reference signals for each resource block, which helps to reduce the transmission power and improve the system capacity. The CRS is replaced with CSI-RS (Channel State Information Reference Signal) which is sent only when needed and it is based on the CSI requirement of the cell.
The official site for 3GPP specifications is https://www.3gpp.org/specifications. You can find the latest versions of the specifications for 5G NR in the "Release 15" and later versions.
You can refer to the specification 38.211 (Physical channels and modulation) specifically section 7.4 "Cell-specific reference signal (CRS)" and section 7.5 "Channel state information-reference signal (CSI-RS)".
Here is an excerpt from the specification 38.211 (Release 16 version) that explains the use of CRS and CSI-RS in 5G NR: "In NR, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used. Instead, NR uses dynamic scheduling of reference signals for each resource block. This is done to improve system capacity and reduce transmission power. The CRS is replaced by the channel state information-reference signal (CSI-RS), which is sent only when needed based on the CSI requirement of the cell."
質問 # 21

質問 # 22
In NSA networking, which of the following factors affect the downlink peak rate of a CPE?
- A. Downlink BLER of 3% or above
- B. CPE location
- C. Downlink transmit power of the NR base station
- D. Uplink transmit power of the CPE
正解：A、B、C
解説：
In Non-standalone (NSA) networking, the downlink peak rate of a CPE is affected by various factors, such as the downlink transmit power of the NR base station, the CPE location, the quality of the radio channel, and the configuration of the network. -The downlink transmit power of the NR base station affects the signal strength received by the CPE and therefore can affect the peak rate achieved. -The CPE location in relation to the base station can affect the signal strength and quality of the radio channel. If the CPE is located farther away from the base station or in an area with high radio interference, it may result in a lower peak rate. -Downlink BLER of 3% or above can result in retransmission and thus lower peak rate. -Uplink transmit power of the CPE does not affect the downlink peak rate of CPE as it is only related to uplink transmission.

Which of the following parameters in core network subscription information restricts the non-GBR rate for a UE?
- A. MBR
- B. SINR
- C. GBR
- D. UE-AMBR

解説：
In 5G Core network, the core network subscription information contains parameters that are used to manage the resources of a UE.
1. UE-AMBR (UE Aggregate Maximum Bit Rate) : It's the maximum bit rate that is allocated to a UE for non-guaranteed bit rate (non-GBR) services. It controls the non-GBR rate for a UE.
質問 # 28
Which of the following statements about PDSCH DMR5 is incorrect?
- A. The front-loaded DMRS is mandatory, and the additional DMRS is optional.
- B. The overhead of type 1 DMRS is less than that of type 2 DMRS.
- C. The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH.
- D. The start symbol of a front-loaded DMRS of a type A PDSCH can be symbol 2.
正解：C
解説：
The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.
You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.

- A. RF fault
- B. BBP fault
- C. Clock exception
- D. Insufficient CPRI bandwidth
正解：A、B、C、D
解説：
According to Huawei official documentation, the following are possible causes of NRDUCELL unavailability: A. RF fault B. BBP fault C. Insufficient CPRI bandwidth D. Clock exception. The RF, BBP, and CPRI bandwidth are all important factors that contribute to the availability of the NRDUCELL. If there is a problem with any of these components, it can cause the NRDUCELL to become unavailable. Additionally, a clock exception, such as an issue with the timing or synchronization of the cell, can also cause the NRDUCELL to become unavailable.
NRDUCELL unavailability can be caused by an RF fault, a BBP fault, insufficient CPRI bandwidth, or a clock exception. According to this page, these are all possible causes of NRDUCELL unavailability.
