Pass the Huawei HCIA-5G-RAN H35-480_V3.0 Questions and answers with CertsForce

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.

A. RSRP (Reference Signal Received Power) is the power level of the reference signals received from the cell, it is used to measure the strength of the signal from the cell, and it is an important parameter for cell selection and handover decisions. C. PCI (Physical Cell Identity) is a unique identifier assigned to each cell in the network, it is used to identify the cell and its system information.

A. Mixed slot is a slot configuration in which at least one downlink/uplink symbol is present, while other symbols can be flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. B. Flexible-slot is a slot configuration in which all symbols are flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. C. Downlink-only slot is a slot configuration in which all symbols are dedicated for downlink transmission, This configuration is mainly used for downlink-centric services such as video streaming or software downloads. D. Uplink-only slot is a slot configuration in which all symbols are dedicated for uplink transmission, this configuration is mainly used for uplink-centric services such as voice calls or video conferencing.

SSB GSCN is the center frequency number of an NR cell. SSB GSCN stands for "SS block group-specific cell number" and is used to identify the center frequency of an NR cell. This value is used in combination with the operating bandwidth of the cell to determine the physical layer resource grid for the cell. As such, it is important for the correct SSB GSCN to be configured for the cell in order to ensure the correct channel coding.

In 5G NR, the SSB (Secondary Synchronization Signal Block) is used to provide the time and frequency synchronization information to the mobile devices. It is transmitted in the frequency domain and it consists of two parts: the SSB GSCN (Secondary Synchronization Signal Block - Group and Sequence Number) and the SSB MIB (Secondary Synchronization Signal Block - Master Information Block).

The SSB GSCN is a unique identifier that indicates the center frequency number of the cell. It is used to identify the cell and to determine the frequency offset of the cell with respect to the carrier frequency.

So, the statement is true, SSB GSCN is the center frequency number of an NR cell. It's worth noting that the SSB MIB contains other system information such as the system bandwidth, the transmission bandwidth configuration, and the number of symbols in a slot.

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.

"The RSRP value of the test terminal can be viewed on the GENEX Probe. A RSRP value of between -60dBm and -90dBm indicates good signal quality. Lower values indicate weaker signals, while higher values indicate stronger signals."

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.

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.

According to Huawei's official documentation, GENEX Assistant is typically applied in the following scenarios:

Wireless network adjustment

Single site verification

Routine network optimization
