質問 # 30
Consider that the UE is performing handover from LTE to NR with the help of features CB007742 / CB008731 . Referring to the picture below, at what stage can the handover be triggered from LTE to NR?
正解：A
解説：
The correct answer is C: From Stage 3 .
In LTE-to-NR mobility, the handover or redirection decision is normally based on a combination of:
LTE serving-cell signal level becoming weak enough, and
NR neighbor-cell signal level becoming strong enough.
From the diagram:
In Stage 1 , LTE is still good and NR is still weak, so LTE-to-NR HO should not be triggered.
In Stage 2 , the NR neighbor signal is improving, but the required combined LTE/NR mobility condition is not yet fully satisfied.
In Stage 3 , the NR neighbor signal has crossed the required NR threshold, while the LTE serving-cell signal has degraded enough to justify moving the UE from LTE to NR. This is the first valid stage where LTE-to- NR HO can be triggered.
In Stage 4 , NR is already clearly strong, but the handover could already have been triggered earlier in Stage 3.
質問 # 31
In a high-mobility network, the maximum cell size must be restricted to 33 km . Which PRACH format and restricted-set type should be used?
正解：D
質問 # 32
In NR SA Option 2, the UE is camped on an SA serving cell. An IRAT handover is triggered for a multi-QCI call, QCI 1 and QCI 6, due to weak coverage of the serving cell. What will happen to both QCIs during the IRAT handover toward LTE?
正解：B
解説：
The correct answer is D.
In 5G SA Option 2, NR works independently with the 5G Core, but interworking with LTE/EPC can be supported for mobility continuity. When IRAT handover toward LTE is triggered due to weak NR coverage, the goal is to preserve the active services during mobility.
For a multi-QCI service:
QCI 1 normally represents the voice bearer, such as VoLTE/IMS voice continuity after movement to LTE.
QCI 6 normally represents a non-GBR data bearer.
During a supported IRAT handover from NR SA to LTE, both the voice bearer and data bearer can be transferred to LTE, assuming proper interworking, bearer mapping, and LTE coverage availability.
Option C is incorrect because IRAT mobility from NR SA to LTE is supported in properly configured networks. Option A is incorrect because the voice bearer is the most critical bearer to preserve. Option B is also not the best answer because the data bearer does not necessarily need to be released during IRAT handover.
Therefore, the expected result is:
Both QCI 1 voice and QCI 6 data continue on LTE.
質問 # 33
In a 5G NSA Option 3x deployment, why should we not define 5G neighbors in LTE sectors where there is no 5G coverage ?
正解：C
解説：
The correct answer is A .
In 5G NSA Option 3x , LTE acts as the Master Cell Group , and NR acts as the Secondary Cell Group , usually added through EN-DC . If 5G NR neighbors are configured in an LTE sector where there is actually no 5G coverage , the LTE eNB may still configure the UE to perform NR measurements.
To perform NR inter-RAT or inter-frequency measurements, the UE may require measurement gaps .
During these gaps, the UE stops normal LTE reception/transmission activities to measure NR frequencies. If there is no real 5G coverage, those gaps become wasted measurement time and can reduce LTE user throughput.
Option B is not the best answer because if there is no 5G coverage, the main issue is not successful SCG addition or handover degradation, but unnecessary measurement activity. Option C is also not correct because redirection from 5G to 4G normally occurs when the UE is already on or connected to 5G coverage, which is not the case here.
Therefore, the main reason is:
LTE throughput degradation due to unnecessary measurement gap configuration.
質問 # 34
A slice supporting sensors and smart meters would be categorized as:
正解：C
解説：
The correct answer is A .
Sensors and smart meters are typical massive IoT use cases. They usually involve a very large number of devices sending small amounts of data, often with low mobility and low power requirements.
This type of traffic fits mMTC , or massive Machine Type Communications .
Why the other options are not correct:
URLLC is used for very low-latency and highly reliable services, such as industrial automation, remote control, or mission-critical applications.
eMBB is used for high-throughput broadband services, such as video, fixed wireless access, or enhanced mobile internet.
DNN is not a slice category. It means Data Network Name and identifies the data network the UE connects to, similar to APN in LTE.
Therefore, a slice supporting sensors and smart meters is categorized as:
mMTC.
