質問 # 23
Which of the following parameters In the NR MIB message indicates the time-domain position of CORESET 0?
- A. SSB-subcarrier offset
- B. Most significant four bits of PDCCH-configSIBl
- C. System frame number
- D. Least significant four bits of PDCCH-configSIBl
正解:D
解説:
In 5G NR, the Master Information Block (MIB) message is transmitted on the Physical Broadcast Channel (PBCH) and contains information that is used by the UEs to synchronize to the cell and obtain basic system information. The parameters in the NR MIB message that indicate the time-domain position of CORESET 0 are the least significant four bits of PDCCH-configSIBl.

質問 # 25
Which of the following 5G network technologies can reduce IoV latency?
- A. Massive MIMO
- B. SDN
- C. NFV
- D. MEC
正解:D
解説:
MEC (Mobile Edge Computing) is a network technology that enables the deployment of computing and storage resources at the edge of the network, closer to the end-users. This can significantly reduce the latency for various applications, such as IoT, AR/VR and IoV. By moving the computing and storage resources closer to the end-users, the data can be processed and stored closer to the source, reducing the time and distance that the data needs to travel. This can reduce the overall latency and improve the user experience.
According to the official GSMA white paper on 5G and IoV, MEC can reduce latency by bringing computing resources closer to the edges of the network. This can be particularly beneficial for IoV applications, which require low latency and high reliability. Additionally, NFV (Network Function Virtualization), Massive MIMO (Multiple Input Multiple Output) and SDN (Software Defined Networking) can also be used to improve performance and reduce latency in 5G networks.

質問 # 37
When a GPS divider is used, the maximum distance between the GPS antenna and the BBU is shortened.
- A. False
- B. True
正解:B
解説:
When a GPS divider is used, the maximum distance between the GPS antenna and the BBU is shortened. This is because the divider splits the signal from the antenna into multiple signals that can be distributed to multiple BBUs, thus reducing the distance between the antenna and the BBUs.

質問 # 41
Generally, the gNodeB synchronizes time information from the OSS. Which of the following commands is used to configure the IP address of the time server?
- A. ADD GPS
- B. ADD IPCLKUNK
- C. ADD OMCH
- D. ADD NTPC
正解:D
解説:
In a gNodeB, the time information is synchronized from the OSS using the Network Time Protocol (NTP). The ADD NTPC command is used to configure the IP address of the NTP server, which is the time server that the gNodeB synchronizes with. This command is used to specify the IP address of the NTP server, the NTP version, and other parameters related to time synchronization.
質問 # 42
If the subcarrier spacing (SCS) of a low-frequency cell Is 30 kHz and the bandwidth of each RB Is 360 kHz, theoretically, what value should the noise (dBm) over the air interface be?
- A. 0
- B. 1
- C. 2
- D. 3
正解:A
解説:
The theoretically noise (dBm) over the air interface should be -116 dBm. The noise is calculated by subtracting the noise figure of the receiver from the thermal noise floor, which is determined by the subcarrier spacing and the bandwidth of each Resource Block (RB). In this case, the subcarrier spacing is 30 kHz and the bandwidth of each RB is 360 kHz, so the thermal noise floor is -116 dBm.
質問 # 43

- A. MOD DSCPMAP
- B. SET PHBMAP
- C. SET DSCPMAP

質問 # 44
What Is the maximum number of pRRUs on a CPRI link for RF combination?
- A. 0
- B. 1
- C. 2
- D. 3
正解:A
解説:
The maximum number of pRRUs on a CPRI link for RF combination is 16. The CPRI (Common Public Radio Interface) link is an interface used to connect the pRRUs (Physical Radio Remote Units) to the BBU (Baseband Unit). The pRRUs contain the radio modules and antennas, while the BBU contains the baseband processing unit. The CPRI link allows the BBU to send and receive data from the pRRUs, enabling them to be combined for RF combination. Sources: [1] Chen, F., and Zhang, Y.
