H35-480_V3.0 Exam Dumps : HCIA-5G-RAN V3.0 Exam

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. For more information, please see this link:

The maximum number of PCIs (Physical Cell Identifiers) supported by a 5G network is 1008. This is specified in 3GPP 5G standard TS 38.211, which states that the maximum number of PCIs that a 5G network can support is 1008.

In 5G, each cell is assigned a unique identifier called the PCI (Physical Cell Identity). The PCI is used to identify the cell and its system information, and it is used for various purposes such as cell selection, handover, and interference management.

According to 3GPP specifications, the maximum number of PCIs that can be supported by a 5G network is 1008, which allows for a large number of cells to be deployed in a network. However, the actual number of PCIs used in a network will depend on the specific deployment scenario, the network architecture, and the capacity requirements of the network.

Cloudification of 5G wireless networks can significantly improve the user rate. Cloudification refers to the process of virtualizing the functions of a network and running them on commodity hardware in a data center, rather than on dedicated hardware in the network itself. In the case of 5G wireless networks, this can be achieved by virtualizing the Base Station (gNB) functions and running them on a cloud platform. This allows for more efficient use of resources and better scalability, which can result in an improved user rate.

Additionally, Cloud-RAN (C-RAN) architecture, which is a cloud-based centralization of the baseband processing functions can also be used to improve the user rate by reducing the number of active base stations required in a given area, and also by allowing for more efficient management of resources and more flexible deployment of services.

However, it's worth noting that the improvement of the user rate is not only limited to cloudification, but it's also related to many other factors such as network design, optimization, and management.
