Huawei H35-481_V2.0 HCIP-5G-RAN V2.0 Exam Exam Practice Test

One of the challenges of 5G network construction is to provide Indoor coverage in large stadiums, where Indoor interference severely affects network coverage and capacity. One of the solutions that can effectively mitigate the interference caused by Indoor coverage with high-density site deployment is sector splitting. This solution involves dividing the cell into multiple smaller cells, each with its own set of antennas and RF parameters. By reducing the number of users and devices in each cell, sector splitting can significantly reduce the amount of interference and improve network coverage and capacity.

If the NRDUCELL corresponding to NRCELL is not set up, then the NRCELL must be unavailable. This is because the NRDUCELL defines the coverage area of an NRCELL. Without the NRDUCELL, the NRCELL cannot be successfully activated and therefore it will remain unavailable.

Interconnection through RF modules (A) is also a supported solution for X2 interconnection between LTE and NR base stations. In this solution, the LTE and NR base stations are connected through RF modules, allowing them to share the same frequency band and resources. This solution is particularly useful for scenarios where there is a need for seamless interworking between LTE and NR networks, such as in the early stages of 5G deployment.

The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.

You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.

The GUI configuration mode in MAE-Deployment can be used to configure parameters in an MO and reconfigure a single NE. It cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs. According to the Huawei official documentation, "The GUI configuration mode can be used to configure parameters in an MO and reconfigure a single NE. However, it cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs."

5G E2E slicing can be used to ensure the QoS and security of smart grid services. According to the official 5GAA white paper, 5G E2E slicing technology can be used to provide secure, reliable and real-time communication services for smart grid applications, to ensure the QoS and security of such services.

According to Huawei's BTS5900 Product Brochure, PnP (Plug and Play) mode can be used for local data configuration if the configuration data of a new BTS5900 base station cannot be loaded remotely. In PnP mode, the BTS5900 automatically obtains the IP address and configuration data from the OMC or other device through DHCP. The BTS5900 also supports manual configuration of the IP address and configuration data.

According to the official 3GPP specification, the DCI of NR does not carry PUSCH power control information. It carries scheduling information for the PUSCH and PDSCH and a PMI report. Reference:

The UE inactivity timer on the NR side expiring and the air interface link on the NR side being abnormal, and a UE reporting SCG Failure Info to the eNodeB, can both trigger the MeNB to release the SgNB. Other actions, such as an inter-SgNB cell change or the MeNB detecting an abnormal X2 link, may also lead to SgNB release, but are not the trigger for it.
