NEW QUESTION # 29
Which of the following channels (signals) can be used for cell measurement in NR?
- A. SSB
- B. DM-RS
- C. PT-RS
- D. CSI-RS
Answer: B,D
Explanation:
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.

MCGONLY: only split to the MCG and D. SCGANDMCG: dynamic data split. The MCGONLY mode is used when all the UE data must be sent to the same MCG, while the SCGANDMCG: dynamic data split mode is used when the data is split between multiple SCGs and MCGs.
NEW QUESTION # 32
According to 3GPP specifications, which of the following is not an RRC state in 5G?
- A. RRC_CONNECTED
- B. RRC_ACTIVE
- C. RRC_INACTIVE
- D. RRC_IDLE
Answer: C
Explanation:
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.
NEW QUESTION # 33
Which of the following files must be prepared when remotely commissioning a gNodeB using the MAE Deployment?

NEW QUESTION # 34
At which layer is downlink data split implemented over the NR air interface in the NSA Option 3x architecture?
- A. Physical layer
- B. MAC layer
- C. PDCP layer
- D. RLC layer
Answer: B
Explanation:
Downlink data split over the NR air interface in the NSA Option 3x architecture is implemented at the medium access control (MAC) layer. The MAC layer is responsible for the management of data transmission over the air interface, including segmentation and reassembly of data packets, scheduling of transmission resources, and error correction. The other layers (RLC, PDCP, and physical) are not involved in the implementation of downlink data split.

In the Non-Stand-Alone (NSA) Option 3x architecture, the control plane functions are handled by the 4G LTE network (EPC), while the user plane functions are handled by the 5G NR network. Data split is a technique that allows to split the user plane data between the 4G LTE and 5G NR networks.
The MAC (Medium Access Control) layer is responsible for controlling the access to the shared wireless medium, and it is where the downlink data split is implemented. In this architecture, the MAC layer in the 5G NR network receives the downlink data from the 4G LTE network and sends it to the physical layer for transmission.
NEW QUESTION # 35
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
Answer: B,C
Explanation:
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.

NEW QUESTION # 36
Which of the following devices is used to implement service slicing on the 5G RAN side?
- A. Antenna
- B. AAU
- C. RRU
- D. BBU
Answer: D
Explanation:
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.
