NEW QUESTION # 10
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 symbols in a slot can be classified as downlink, uplink, or flexible.
- D. The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
Answer: A,B,C
Explanation:
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.

NEW QUESTION # 16
Which of the following parameters is related to the frequency-domain position of PBCH DMRSs?
- A. Bandwidth
- B. PCI
- C. Cell ID
- D. SI-RNTI
Answer: B
Explanation:
PCI (Physical Cell Identity) is related to the frequency-domain position of PBCH DMRSs (Physical Broadcast Channel Demodulation Reference Signals) The PBCH DMRSs are used to demodulate the Physical Broadcast Channel (PBCH) which contains system information such as the cell identity, system bandwidth, and the downlink carrier frequency.
The PBCH DMRSs are transmitted in the frequency domain, and their position is determined by the Physical Cell Identity (PCI). The PCI is a unique identifier assigned to each cell in the network, and it's used to identify the cell and its system information.
So, the correct answer is B. PCI. It's worth noting that the other parameters you mentioned are also related to the 5G system information and the cell configuration. Cell ID is a unique identifier assigned to each cell, SI-RNTI (System Information RNTI) is a unique identifier assigned to the system information, and Bandwidth is the amount of frequency resources allocated to the cell.

NEW QUESTION # 18
At which layer is downlink data split implemented over the NR air interface in the NSA Option 3x architecture?
- A. RLC layer
- B. Physical layer
- C. MAC layer
- D. PDCP layer
Answer: C
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 # 20
E2E network device update is required for the evolution from 5G NSA networking to SA networking.
- A. False
- B. True
Answer: B
Explanation:
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.
NEW QUESTION # 21
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. Dynamic route configuration
- B. Direct route configuration
- C. Destination address route configuration
- D. Source address route configuration
Answer: C
Explanation:
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
