In NSA networking, which of the following objects are unnecessary to configrued for a gNodeB in SI self-setup scenarios?
- A. SCTPHOST
- B. USERPLANEPEER
- C. SCTPPEER
- D. USERPLANEHOST
Answer: A,D
Explanation:
In NSA networking, In self-setup scenarios, the USERPLANEHOST and SCTPHOST objects are unnecessary to configure for a gNodeB. The USERPLANEHOST object is used to configure the IP address of the user plane host, and the SCTPHOST object is used to configure the IP address of the SCTP host. In self-setup scenarios, the gNodeB automatically obtains the IP addresses of the user plane host and SCTP host from the S1-MME or S1-U peer. The USERPLANEPEER and SCTPPEER objects are necessary to configure for a gNodeB in SI self-setup scenarios. They are used to configure the IP address of the user plane peer and SCTP peer, respectively.
NEW QUESTION # 32
What Is the maximum number of pRRUs on a CPRI link for RF combination?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
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.

NEW QUESTION # 34
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
Answer: A
Explanation:
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."
NEW QUESTION # 35
Which of the following may cause exceptions In the GPS clock source?
- A. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected.
- B. The GPS is not installed in the correct position, and the number of locked satellites is less than 4.
- C. The GPS satellite card Is faulty.
- D. High signal attenuation is caused due to improper GPS remote distance.
Answer: A,B,C,D
Explanation:
1. High signal attenuation is caused due to improper GPS remote distance. B. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected. C. The GPS is not installed in the correct position, and the number of locked satellites is less than 4. D. The GPS satellite card Is faulty.
Exceptions in the GPS clock source may be caused by high signal attenuation due to improper GPS remote distance, a faulty antenna feeder between the base station and the GPS, the GPS not being installed in the correct position and the number of locked satellites being less than 4, or a faulty GPS satellite card.
NEW QUESTION # 36
Which of the following statements about NR subcarriers are incorrect?
- A. The smaller the subcarrier spacing, the lower the power spectral density.
- B. The larger the subcarrier spacing, the larger the number of symbols.
- C. The smaller the subcarrier spacing, the larger the CP length and the more suitable it becomes for wide coverage.
- D. The larger the subcarrier spacing, the larger the slot length.
Answer: C
NEW QUESTION # 37
Which of the following parameters In the NR MIB message indicates the time-domain position of CORESET 0?
- A. SSB-subcarrier offset
- B. System frame number
- C. Least significant four bits of PDCCH-configSIBl
- D. Most significant four bits of PDCCH-configSIBl
Answer: C
Explanation:
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.
NEW QUESTION # 38
