NEW QUESTION # 36
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."

Which of the following logs is used to analyze the relationship between gNodeB device faults and operations?
- A. Debug log
- B. Security log
- C. Run log
- D. Operation log
Answer: A
Explanation:
The debug log is used to analyze the relationship between gNodeB device faults and operations. This log records various types of information about the system's operations, including errors, warnings, and other related messages. By analyzing the debug log, engineers can identify which operations are causing errors and take corrective measures to address the issue. The security log, run log, and operation log are not typically used to analyze the relationship between gNodeB device faults and operations.

NEW QUESTION # 46
Which of the following channels is not involved in NR random access of a UE?
- A. PUCCH
- B. PRACH
- C. PUSCH
- D. PDCCH
Answer: C
Explanation:
In 5G NR, the random access procedure is used by a UE to establish a connection with the base station. The channels involved in the NR random access of a UE are:
1. PDCCH (Physical Downlink Control Channel): The PDCCH is used by the base station to transmit control information to the UE, such as scheduling assignments and uplink grants.
2. PRACH (Physical Random Access Channel): The PRACH is used by the UE to transmit the random access preamble to the base station.
3. PUCCH (Physical Uplink Control Channel): The PUCCH is used by the UE to transmit control information to the base station, such as uplink scheduling requests and HARQ feedback.
4. PUSCH (Physical Uplink Shared Channel) is not involved in NR random access of a UE, it is a shared channel used to transmit the uplink data and control information.
