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

A. Site deployment list: A document that provides information about the location and basic configuration of the gNodeB, including the site name, coordinates, azimuth, and antenna type. B. Data configuration file of the base station: A file that contains the detailed configuration information of the gNodeB, such as IP address, system parameters, and software version. It is used to configure the gNodeB remotely. C. Base station software package of the target version: A software package that contains the software version that needs to be installed on the gNodeB. D. Base station license: A license file that is required to activate and use the gNodeB.

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).

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 MML command to query version information relating to the software stored on the gNodeB is LST SOFTWARE. This command will list the version information of the software installed on the gNodeB, including the version numbers, software names, and more. This is stated in the official Huawei documentation, which states: "Use the LST SOFTWARE command to check the version information of the software installed on the gNodeB, including the version numbers, software names, and more." Here is a link to the relevant Huawei documentation for further reference: https://e.huawei.com/en/products/base-station/bbu5900/overview

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 3GPP specifications, the RRC states in 5G are RRCIDLE, RRCACTIVE, and RRCCONNECTED. RRCINACTIVE is not an RRC state defined in 3GPP specifications. RRCIDLE is the state when the UE is not attached to an eNB and is not actively monitoring for paging. RRCACTIVE is the state when the UE is attached to an eNB and is actively monitoring for paging. RRCCONNECTED is the state when the UE has an established RRC connection with an eNB.

The RRC is a protocol that controls the radio resources of the mobile device in a cellular network. 3GPP (3rd Generation Partnership Project) has defined several RRC states for 5G NR (New Radio) to manage the radio resources of the mobile device. These states are:

A. RRC_IDLE: The mobile device is not connected to any cell and is not actively searching for a cell to connect to. B. RRC_ACTIVE: The mobile device is connected to a cell and is actively communicating with it. C. RRC_CONNECTED: The mobile device is connected to a cell, but it's not actively communicating with it. It is in a low power state and is only listening to the paging channel for incoming calls or data.

So, the correct answer is D. RRC_INACTIVE, is not an RRC state in 5G according to 3GPP specifications. It's worth noting that the RRC state of the mobile device can change dynamically based on the network conditions, service requirements, and the mobile device's power management.

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

Wireless network adjustment

Single site verification

Routine network optimization

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.
