https://www.gtigroup.org/d/file/Resources/rep/2019-07-05/cbf7810256b4c312c460863fcb77bd58.pdf In 5G NR, the SSB (Secondary Synchronization Signal Block) is used to provide the time and frequency synchronization information to the mobile devices. It is transmitted in the frequency domain and it consists of two parts: the SSB GSCN (Secondary Synchronization Signal Block – Group and Sequence Number) and the SSB MIB (Secondary Synchronization Signal Block – Master Information Block).
The SSB GSCN is a unique identifier that indicates the center frequency number of the cell. It is used to identify the cell and to determine the frequency offset of the cell with respect to the carrier frequency.
So, the statement is true, SSB GSCN is the center frequency number of an NR cell. It’s worth noting that the SSB MIB contains other system information such as the system bandwidth, the transmission bandwidth configuration, and the number of symbols in a slot.

Q33. According to 3GPP specifications, which of the following is not an RRC state in 5G?

RRC_IDLE

RRC_ACTIVE

RRC_CONNECTED

RRC_INACTIVE

According to 3GPP specifications, the RRC states in 5G are RRCIDLE, RRCACTIVE, and RRCCONNECTED. RRCINACTIVE is not an RRC state defined in 3GPP specifications. RRCIDLE is the state when the UE is not attached to an eNB and is not actively monitoring for paging. RRCACTIVE is the state when the UE is attached to an eNB and is actively monitoring for paging. RRCCONNECTED is the state when the UE has an established RRC connection with an eNB.
The RRC is a protocol that controls the radio resources of the mobile device in a cellular network. 3GPP (3rd Generation Partnership Project) has defined several RRC states for 5G NR (New Radio) to manage the radio resources of the mobile device. These states are:
1. RRC_IDLE: The mobile device is not connected to any cell and is not actively searching for a cell to connect to. B. RRC_ACTIVE: The mobile device is connected to a cell and is actively communicating with it. C. RRC_CONNECTED: The mobile device is connected to a cell, but it’s not actively communicating with it. It is in a low power state and is only listening to the paging channel for incoming calls or data.
So, the correct answer is D. RRC_INACTIVE, is not an RRC state in 5G according to 3GPP specifications. It’s worth noting that the RRC state of the mobile device can change dynamically based on the network conditions, service requirements, and the mobile device’s power management.

Q35. Which type of information about NR cells is carried in the neighboring NR cell MRs reported by UEs? (Choose all that Apply)

RSRP

MACCE

PCI

1. RSRP (Reference Signal Received Power) is the power level of the reference signals received from the cell, it is used to measure the strength of the signal from the cell, and it is an important parameter for cell selection and handover decisions. C. PCI (Physical Cell Identity) is a unique identifier assigned to each cell in the network, it is used to identify the cell and its system information.

Q36. E2E network device update is required for the evolution from 5G NSA networking to SA networking.

True

False

End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.
It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

Q37. Which of the following NR channels or signals supports static and dynamic power control?

PDCCH

PUSCH

PBCH

Static power control is used to adjust the transmission power of UEs to meet the requirements of cell-edge UEs, while dynamic power control is used to adjust the transmission power of UEs to meet the requirements of the uplink channel quality. PUSCH is the channel used by the UE to transmit data to the gNodeB and supports both static and dynamic power control.
Reference:
“The PUSCH (Physical Uplink Shared Channel) supports both static and dynamic power control. Static power control is used to adjust the transmission power of UEs to meet the requirements of cell-edge UEs, while dynamic power control is used to adjust the transmission power of UEs to meet the requirements of the uplink channel quality.” in Huawei official website.

1ms

Q40. Which of the following channels (signals) can be used for cell measurement in NR?

DM-RS

CSI-RS

PT-RS

SSB

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.

Q41. If the length of the CPRI optical fiber between a BBU and an RRU exceeds 150 m, you are advised to use a multimode fiber.

True

False

The Common Public Radio Interface (CPRI) is a standard that defines the interface between the BBU (baseband unit) and the RRU (remote radio unit) in a wireless base station. The BBU and the RRU are connected by an optical fiber cable, known as the CPRI optical fiber.
The CPRI optical fiber is used to transport the digital baseband signals between the BBU and the RRU. The distance between the BBU and the RRU can be up to several kilometers, but the standard CPRI specification only supports a maximum distance of 150m between the BBU and RRU using single-mode fiber. If the distance exceeds 150m, multimode fiber should be used to extend the distance between the BBU and the RRU.

Q42. Which of the following actions are involved in NAS procedure management in 5G?

Q45. A larger CQI value indicates a better channel quality.

True

False

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.
A larger CQI value indicates better channel quality, higher link quality and a better signal-to-noise ratio. When the channel quality is good, the UE can report a larger CQI value, and the eNodeB can use a higher modulation and coding scheme to achieve higher data rate and better performance. On the other hand, when the channel quality is poor, the UE will report a smaller CQI value, and the eNodeB will use a lower modulation and coding scheme to reduce the error rate. It’s worth noting that, the exact range of CQI values and the specific mapping between CQI values and modulation/coding schemes may vary depending on the specific network deployment, it’s always recommended to refer to the official guide or document of the product for detailed and accurate information.

Q46. According to 3GPP specifications, which of the following is not an RRC state in 5G?

RRU

On the 5G RAN side, Service Slicing is implemented using a Base Band Unit (BBU). A BBU is a device that performs baseband processing functions, such as modulation, demodulation, and encoding/decoding of signals. It is also responsible for the connection to the core network and the management of the radio resources. In 5G, BBU is a key component to support service slicing, where different services can be assigned different slices of the network resources, such as bandwidth, power, and quality of service. This allows for more efficient use of resources and better management of different types of traffic, such as broadband and low latency services.

Q49. In SA networking, the mobile country code (MCC) and mobile network code (MNC) information added on the gNodeB must be consistent with the PLMN information on the core network.
