質問 # 10
Which of the following NR channels or signals supports static and dynamic power control?
- A. PBCH
- B. PUSCH
- C. PDCCH
- D. SS
正解：B
解説：
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.
質問 # 11
If multiple IP addresses are planned for a gNodeB and the next-hop IP addresses are different, which of the following route configurations is more suitable?
- A. Destination address route configuration
- B. Direct route configuration
- C. Source address route configuration
- D. Dynamic route configuration
正解：A
解説：
In a gNodeB (generic NodeB), the routing table is used to determine the next-hop IP address for a given destination IP address. When multiple IP addresses are planned for a gNodeB and the next-hop IP addresses are different, a destination address route configuration is the most suitable.
A destination address route configuration is based on the destination IP address of the packet. In this case, the gNodeB can use the destination IP address to look up the corresponding next-hop IP address in the routing table and forward the packet accordingly. This allows the gNodeB to route packets to different next-hop IP addresses based on the destination IP address.
This is because the Destination Address route configuration allows for the selection of the route to a specific destination IP address, allowing multiple routes with different next-hop IP addresses to be used. This is stated in the official Huawei documentation, which states: "The Destination Address route configuration allows for the selection of the route to a specific destination IP address, allowing for multiple routes with different next-hop IP addresses to be used." Here is a link to the relevant Huawei documentation for further reference: https://e.huawei.com/en/products/base-station/bbu5900/overview

On an NSA network, the eNodeB immediately triggers the SgNB addition procedure after a UE attaches to the LTE network. If the SgNB addition fails, the eNodeB attempts to add the SgNB again until it is successful.
- A. True
- B. False
正解：A
解説：
On an NSA network, the eNodeB immediately triggers the SgNB addition procedure after a UE attaches to the LTE network. If the SgNB addition fails, the eNodeB attempts to add the SgNB again until it is successful. The eNodeB may also trigger an SgNB addition procedure if it detects a change in its coverage area or if it detects a new SgNB or an SgNB that has been moved.

質問 # 21
Which of the following devices is used to implement service slicing on the 5G RAN side?
- A. AAU
- B. RRU
- C. BBU
- D. Antenna
正解：C
解説：
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.

質問 # 25
Which of the following statements about the NR slot structure are correct? (Choose All that Apply)
- A. Downlink self-contained slots can be used to transmit uplink data and SRSs.
- B. Downlink slots can only be used to transmit downlink data.
- C. The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
- D. The symbols in a slot can be classified as downlink, uplink, or flexible.
正解：A、B、D
解説：
1. NR downlink slots are used to transmit downlink data and control information, such as channel state information (CSI) and downlink control information (DCI). B. Downlink self-contained slots are also called as "Downlink Shared Channels (DL-SCH) slots", they can be used to transmit downlink data, but also can be used to transmit uplink control information (UCI) and sounding reference signals (SRS) in the downlink direction.
2. The symbols in a slot can be classified as downlink, uplink, or flexible, meaning that the symbols can be used to transmit data in either direction, or to transmit control information.
It's worth noting that the NR slot structure is designed to be flexible and efficient, it allows for a variable slot duration and a variable number of symbols, depending on the subcarrier spacing and the number of resource blocks used. This flexibility is intended to support a wide range of services and traffic types.

質問 # 30
Which of the following actions are involved in NAS procedure management in 5G? (Choose all that Apply)
- A. RRC reestablishment
- B. Registration management
- C. RRC connection setup
- D. Session management
正解：B、C、D
解説：
NAS (Non-Access Stratum) procedure management in 5G involves three specific actions: registration management, session management, and RRC connection setup. Registration management involves sending and receiving of NAS messages related to the establishment of user-network connections, such as attach and detach procedures. Session management involves sending and receiving of NAS messages related to the management of user session related information, such as security context management. RRC connection setup involves sending and receiving of NAS messages related to the establishment, modification, and release of RRC connections. RRC reestablishment is not involved in NAS procedure management in 5G.

In NSA networking, which of the following modes is used to anchor 5G NR?
- A. OGSM
- B. WCDMA
- C. CDMA
- D. LTE
正解：D
解説：
Explanation
The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network
