質問 # 42
An NR CQI value represents a coding scheme and coding efficiency. How many bits does a CQI value reported by a UE have?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
An NR CQI value represents a coding scheme and coding efficiency, and they are reported in the form of 8 bits by a UE. According to the official Huawei documentation, "The 8-bit long CQI value maps to a coding scheme and coding efficiency that can be used for Transport Block (TB) size selection." CQI (channel quality indicator) is a value that represents the channel quality of the wireless link between a UE (user equipment) and an eNodeB (base station) in an NR (New Radio) network. The UE reports the CQI value to the eNodeB, which uses it to determine the optimal coding scheme and modulation for the downlink transmissions to that UE.
The CQI value is reported by UE to the eNodeB, it's a value that indicates the channel quality of the link between the UE and the eNodeB. The CQI value is encoded in 8 bits, which allows for a total of 256 different CQI values.

What is the maximum number of PCIs supported by a 5G network?
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
https://www.5gworldpro.com/blog/2020/11/11/what-is-difference-between-pci-in-4g-lte-and-pci-in-5g-nr/
The maximum number of PCIs (Physical Cell Identifiers) supported by a 5G network is 1008.
This is specified in 3GPP 5G standard TS 38.211, which states that the maximum number of PCIs that a 5G network can support is 1008.
In 5G, each cell is assigned a unique identifier called the PCI (Physical Cell Identity).
The PCI is used to identify the cell and its system information, and it is used for various purposes such as cell selection, handover, and interference management.
According to 3GPP specifications, the maximum number of PCIs that can be supported by a 5G network is 1008, which allows for a large number of cells to be deployed in a network. However, the actual number of PCIs used in a network will depend on the specific deployment scenario, the network architecture, and the capacity requirements of the network.

F-OFDM over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. Which of the following types of subcarrier spacing is not supported by Sub6G?
- A. 30KHz
- B. 120KHz
- C. 15KHz
- D. 60KHZ
正解：B
解説：
F-OFDM (Filtered Orthogonal Frequency Division Multiplexing) over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. F-OFDM is a 5G physical layer waveform that is designed to provide high spectral efficiency, low complexity and low latency. It uses a flexible subcarrier spacing, which can be adjusted to meet the requirements of different 5G services. The subcarrier spacing can be 15KHz, 30KHz, 60KHz, or 120KHz.
Sub-6GHz 5G networks are designed to provide wide-area coverage and support high data rate services such as mobile broadband, IoT, and critical communications. Sub-6GHz band is mainly used for 5G deployment in rural areas, and in-building coverage.
Therefore, the subcarrier spacing that is not supported by Sub-6GHz is 120KHz. So the correct answer is A. 120KHz. It's worth noting that each subcarrier spacing has its own advantages and disadvantages. 120KHz spacing is mainly used for low mobility services such as fixed wireless access, while 15KHz spacing is mainly used for high mobility services such as mobile broadband.
質問 # 51
Which of the following channels (signals) can be used for cell measurement in NR?
- A. CSI-RS
- B. DM-RS
- C. PT-RS
- D. SSB
正解：A、B
解説：
1. DM-RS (Demodulation Reference Signals) are transmitted in the frequency domain, they are used to demodulate the downlink data and control channels, and they can be used for cell measurement such as cell identification, cell reselection, and handover. B. CSI-RS (Channel State Information Reference Signals) are also transmitted in the frequency domain, they are used to provide channel state information for downlink data and control channels, and they can be used for cell measurement such as link adaptation, beamforming and interference management.
DM-RS stands for Demodulation Reference Signal and is used for channel estimation in the frequency domain. CSI-RS stands for Channel State Information Reference Signal and is used for channel estimation in the time-frequency domain. PT-RS and SSB are not channels (signals) that can be used for cell measurement in NR.
質問 # 52
Which of the following methods can be used by a gNodeB to obtain downlink channel characteristics? (Choose All that Apply)
- A. Uplink SRS signal
- B. DMRS of the uplink PUSCH of the UE
- C. Downlink DMRS signal
- D. UE-reported uplink PMI
正解：B、C
解説：
The correct answers are A. DMRS of the uplink PUSCH of the UE and B. Downlink DMRS signal. According to the official Huawei documentation, gNodeBs can use downlink DMRS signals or the DMRS of the uplink PUSCH of the UE to obtain downlink channel characteristics. The downlink DMRS signals contain information about the downlink channel characteristics, and the DMRS of the uplink PUSCH of the UE can be used to measure the uplink channel characteristics. The uplink SRS and PMI signals reported by the UE are used to determine the uplink channel characteristics.
