H35-480_V3.0 HCIA-5G-RAN V3.0 Exam Questions and Answers

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

CQI (channel quality indicator) is a value that represents the channel quality of the wireless link between a UE (user equipment) and an eNodeB (base station) in an NR (New Radio) network. The UE reports the CQI value to the eNodeB, which uses it to determine the optimal coding scheme and modulation for the downlink transmissions to that UE.

A larger CQI value indicates better channel quality, higher link quality and a better signal-to-noise ratio. When the channel quality is good, the UE can report a larger CQI value, and the eNodeB can use a higher modulation and coding scheme to achieve higher data rate and better performance. On the other hand, when the channel quality is poor, the UE will report a smaller CQI value, and the eNodeB will use a lower modulation and coding scheme to reduce the error rate. It's worth noting that, the exact range of CQI values and the specific mapping between CQI values and modulation/coding schemes may vary depending on the specific network deployment, it's always recommended to refer to the official guide or document of the product for detailed and accurate information.

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

• Wireless network adjustment
• Single site verification
• Routine network optimization

A. 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 non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network
