NEW QUESTION # 41
Which of the following 5G network technologies can reduce IoV latency?
- A. NFV
- B. Massive MIMO
- C. SDN
- D. MEC
Answer: D
Explanation:
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.

- A. Faster downlink hybrid automatic repeat request (HARQ) feedback and UL data scheduling to reduce the RTT.
- B. Prolonged sounding reference signal (SRS) transmission period to track fast channel changes and Improve MIMO performance.
- C. High requirements on latency of terminal hardware processing.
- D. Increased GP overhead due to frequent uplink-downlink switching.
Answer: D
Explanation:
Increased GP overhead due to frequent uplink-downlink switching. Self-contained slots are designed to reduce the round-trip time (RTT) by providing faster downlink hybrid automatic repeat request (HARQ) feedback and UL data scheduling, as well as prolonged sounding reference signal (SRS) transmission periods to track fast channel changes and improve MIMO performance. However, they do not involve increased GP overhead due to frequent uplink-downlink switching. High requirements on latency of terminal hardware processing may be involved, depending on the implementation.

The ESN of a gNodeB changes after the main control board Is replaced.
- A. False
- B. True
Answer: B
Explanation:
When the main control board of a gNodeB is replaced, the Equipment Serial Number (ESN) of the gNodeB also changes. The ESN is a unique identifier of the gNodeB that is programmed into the main control board and is used to identify the specific gNodeB in the network. So when the main control board is replaced, the ESN also changes.
NEW QUESTION # 45
In NSA networking, which of the following factors affect the downlink peak rate of a CPE?
- A. CPE location
- B. Downlink transmit power of the NR base station
- C. Uplink transmit power of the CPE
- D. Downlink BLER of 3% or above
Answer: A,B,D
Explanation:
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.

NEW QUESTION # 48
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
Answer: A
Explanation:
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.

NEW QUESTION # 51
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. False
- B. True
Answer: B
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."

If the dock of a base station is locked and the base station fails to obtain clock source signals, which of the following clock states is the base station in?
- A. Fast tracking
- B. Free running
- C. Holdover
- D. Locked
Answer: C
Explanation:
The base station is in a Holdover state when the dock of a base station is locked and the base station fails to obtain clock source signals. Holdover is a state during which the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. According to the Huawei official documentation, "when the clock source is lost, the base station enters the holdover state. In the holdover state, the base station uses the last known frequency and time information to maintain synchronization and clock accuracy. Holdover time is the duration for which the base station can maintain synchronization after the clock source is lost."
