Huawei H35-480_V3.0 HCIA-5G-RAN V3.0 Exam Practice Test

Answer : B

'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.'

Answer : B, C

According to Huawei's official documentation, gNodeBs send TPC (Transmit Power Control) commands to UEs over PDCCHs to control the transmit power of PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel).

'gNodeBs send TPC (Transmit Power Control) commands to UEs over PDCCHs to control the transmit power of PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel).' in Huawei official website.

Answer : B

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.

'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.

Answer : C

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.

'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.

Answer : A

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.

Answer : A

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.

Answer : B

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.
