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

An NR CQI value represents a coding scheme and coding efficiency, and they are reported in the form of 8 bits by a UE. According to the official Huawei documentation, "The 8-bit long CQI value maps to a coding scheme and coding efficiency that can be used for Transport Block (TB) size selection."

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.

The CQI value is reported by UE to the eNodeB, it's a value that indicates the channel quality of the link between the UE and the eNodeB. The CQI value is encoded in 8 bits, which allows for a total of 256 different CQI values.

-"In single site verification, the typical ping packet size is 32 bytes and 1500 bytes, the typical interval is 1s." in Huawei official website.

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), VLAN scanning is used to detect VLANs in a network. The VLAN scanning process is initiated on the base station and requires the base station to send a query to the Layer 2 switch. The query contains the VLAN ID, and the Layer 2 switch then responds with the list of interfaces that are associated with that VLAN ID. Configuration on the LMT is used to configure the VLAN and assign it to the base station. Finally, remote DHCP assignment is used to assign IP addresses to the base station from the DHCP server.

The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.

In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.

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.
