A 5G UE measures the signal-to-interference-and-noise ratio (SINR) at the cell-specific reference

signal (CSI-RS) to report channel quality information such as the CQI, RI, and PMI to a gNodeB. The

CSI-RS SINR is used to determine the modulation and coding scheme (MCS) index, which is then used

by the gNodeB to select the modulation and code rate for the transport block.

CQI (channel quality indicator), RI (rank indicator), and PMI (precoding matrix indicator) are all

parameters that are used to indicate the channel quality of the wireless link between a UE and a

gNodeB in a 5G network. These parameters are reported by the UE to the gNodeB and are used to

determine the optimal modulation and coding schemes for the downlink transmissions.

To report these parameters, the UE needs to measure the channel quality, the UE measures the SINR

(Signal-to-Interference-plus-Noise Ratio) of specific signals to report the channel quality information.

According to the 3GPP TS 24.008 V15.2.0 (https://www.3gpp.org/DynaReport/24008.htm), after the

cell search is complete, a 5G UE automatically selects a PLMN based on the priority sequence. The

UE will preferentially select U-PLMN (User Preferred PLMN) for registration. U-PLMN is the PLMN

that the user has selected manually or that the user has previously registered with, and it has the

highest priority. If U-PLMN is not available, the UE will select RPLMN (Registered PLMN), which is the

last registered PLMN. If RPLMN is not available, the UE will select HPLMN (Home PLMN), which is the

PLMN that is permanently stored in the UE. Finally, if HPLMN is not available, the UE will select

EHPLMN (Equivalent HPLMN), which is the PLMN with the same MCC and MNC as HPLMN.

"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."

The Sl-U interface is a signaling interface between the 5G CN and the 5G RAN in NSA networking. It

uses the SCTP (Stream Control Transmission Protocol) to transport the signaling messages between

the 5G CN and the 5G RAN.

The DSP SCTPLNK command can be used to check the status of the SCTP links between the 5G CN

and the 5G RAN, it can show the SCTP link status, local and peer IP address, local and peer port

number, association status, and more.

The imbalance between uplink and downlink coverage in C-band is not fixed, it varies depending on

the network configuration, location, and other factors. Generally speaking, it's hard to provide an

exact number for this imbalance, as it depends on the specific network conditions and the

equipment used.

However, a common practice is to use more power in downlink than uplink, this is due to the fact

that downlink is more sensitive to path loss than uplink, and also because the downlink signal is

intended to cover a larger area than the uplink. Therefore, the imbalance is commonly in the range

of 3 to 6 dB, and it's more likely to be at the lower end of that range. So, the correct answer is B. 3dB

It's worth noting that the C-band is not the most popular frequency band for 5G network

deployment, it's just one of the many frequency bands that are being used for 5G deployment, and

the most popular frequency bands for 5G deployment vary depending on the country, region, and

operator.

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

1. The UBBP board in the BBU5900 provides CPRI (Common Public Radio Interface) ports for

communication with RF (Radio Frequency) modules. CPRI is an interface standard that is used to

transfer baseband signal data between the BBU and the RF modules. D. The UBBP board also

processes uplink and downlink baseband signals. This includes signal demodulation, decoding, and

modulation, as well as error correction, signal filtering, and other signal processing functions.

:

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. For more

H110V6 refers to a scenario where there are 110 horizontal and 6 vertical antenna elements installed

on the gNodeB, which is ideal for providing coverage in high-rise office buildings. The high number of

horizontal antenna elements allows for high-density deployment, which can improve the coverage

and capacity of the network in these types of environments.

Reference:

"H110V6 can be used to cover high-rise buildings, such as office buildings and hotels, which have

complex indoor environments. The high number of horizontal antenna elements can provide strong

coverage and capacity." in Huawei official website.

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.

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.
