MEC (Mobile Edge Computing) is a network technology that enables the deployment of computing

and storage resources at the edge of the network, closer to the end-users. This can significantly

reduce the latency for various applications, such as IoT, AR/VR and IoV. By moving the computing and

storage resources closer to the end-users, the data can be processed and stored closer to the source,

reducing the time and distance that the data needs to travel. This can reduce the overall latency and

improve the user experience.

According to the official GSMA white paper on 5G and IoV, MEC can reduce latency by bringing

computing resources closer to the edges of the network. This can be particularly beneficial for IoV

applications, which require low latency and high reliability. Additionally, NFV (Network Function

Virtualization), Massive MIMO (Multiple Input Multiple Output) and SDN (Software Defined

Networking) can also be used to improve performance and reduce latency in 5G networks.

According to Huawei's 5G AAU Product Brochure, a 64T64R AAU typically has a maximum output

power of 40W. This power is split between the 64 transmitters, so each transmitter has an output

power of 0.625W. The output power of an AAU can be adjusted depending on the specific

requirements.

After the PA reconfiguration of a 5G base station in SA networking, it is necessary to check whether

cell-related alarms are reported, whether the 5G cell services are normal, and whether the PCI on

the NR side has taken effect on the NE. These checks are necessary to ensure that the reconfiguration

has been successful.

The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol

of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be

configured as the first symbol of PDSCH or as the second symbol of PDSCH.

You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP

5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the

configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature

of it.

In 5G Core network, the core network subscription information contains parameters that are used to

manage the resources of a UE.

1. UE-AMBR (UE Aggregate Maximum Bit Rate) : It's the maximum bit rate that is allocated to a UE

for non-guaranteed bit rate (non-GBR) services. It controls the non-GBR rate for a UE.

In a gNodeB, the time information is synchronized from the OSS using the Network Time Protocol

(NTP). The ADD NTPC command is used to configure the IP address of the NTP server, which is the

time server that the gNodeB synchronizes with. This command is used to specify the IP address of

the NTP server, the NTP version, and other parameters related to time synchronization.

The statement A is incorrect. The larger the subcarrier spacing [1], the shorter the symbol duration

on each subcarrier, not the larger number of symbols. Statement B is also incorrect. The larger the

subcarrier spacing [1], the larger the CP length and the more suitable it becomes for wide coverage.

Statement C is correct. The smaller the subcarrier spacing, the lower the power spectral density.

Statement D is incorrect. The larger the subcarrier spacing [1], the shorter the slot length.

The UBBP board is added to the base station when it is reset, and you need to log in to the LMT again

in order to access the new UBBP board. The UBBP board is used for configuration, monitoring, and

maintenance of the base station.

According to Huawei's official documentation, when the UBBP (Universal Baseband Processing)

board is added, the base station is reset and you need to log in to the LMT (Local Management

Terminal) again. The addition of other boards (OUMPT, UPEU, UEIU) may not require a reset and re-

login.

In NSA networking, In self-setup scenarios, the USERPLANEHOST and SCTPHOST objects are

unnecessary to configure for a gNodeB. The USERPLANEHOST object is used to configure the IP

address of the user plane host, and the SCTPHOST object is used to configure the IP address of the

SCTP host. In self-setup scenarios, the gNodeB automatically obtains the IP addresses of the user

plane host and SCTP host from the S1-MME or S1-U peer. The USERPLANEPEER and SCTPPEER

objects are necessary to configure for a gNodeB in SI self-setup scenarios. They are used to configure

the IP address of the user plane peer and SCTP peer, respectively.

According to the Huawei official documentation, "SCTP tracing can be used to check the SCTP

protocol-related information and locate faults on the user-plane path. The SCTP tracing result can be

used to check the SCTP connection status, SCTP message sending and receiving, and other

information." GTPU trace, Cell DT trace, and NG interface trace can also be used to locate faults on

the user-plane path but SCTP tracing is the most suitable method.

5G E2E slicing can be used to ensure the QoS and security of smart grid services. According to the

official 5GAA white paper, 5G E2E slicing technology can be used to provide secure, reliable and real-

time communication services for smart grid applications, to ensure the QoS and security of such

services. Reference: https://www.5gaa.org/wp-content/uploads/2019/03/5G-AA-White-Paper-onSmart-Grid.pdf

When a GPS divider is used, the maximum distance between the GPS antenna and the BBU is

shortened. This is because the divider splits the signal from the antenna into multiple signals that

can be distributed to multiple BBUs, thus reducing the distance between the antenna and the BBUs.

In Non-standalone (NSA) networking, the downlink peak rate of a CPE is affected by various factors,

such as the downlink transmit power of the NR base station, the CPE location, the quality of the radio

channel, and the configuration of the network. -The downlink transmit power of the NR base station

affects the signal strength received by the CPE and therefore can affect the peak rate achieved. -The

CPE location in relation to the base station can affect the signal strength and quality of the radio

channel. If the CPE is located farther away from the base station or in an area with high radio

interference, it may result in a lower peak rate. -Downlink BLER of 3% or above can result in

retransmission and thus lower peak rate. -Uplink transmit power of the CPE does not affect the

downlink peak rate of CPE as it is only related to uplink transmission.

According to the official 3GPP specification, the DCI of NR does not carry PUSCH power control

information. It carries scheduling information for the PUSCH and PDSCH and a PMI report.

The network layer in the transport protocol stack provides functions such as addressing and route

selection. It is responsible for finding the best route for data packets to travel from the source to the

destination. It also provides logical addressing and packet routing. The network layer does not

provide the transmission of binary data flows, MAC forwarding, or physical medium access.
