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

According to the 3GPP TS 24.008 V15.2.0 ( after the cell search is complete, a 5G UE automatically selects a PLMN based on the priority sequence. The UE will preferentially select U-PLMN (User Preferred PLMN) for registration. U-PLMN is the PLMN that the user has selected manually or that the user has previously registered with, and it has the highest priority. If U-PLMN is not available, the UE will select RPLMN (Registered PLMN), which is the last registered PLMN. If RPLMN is not available, the UE will select HPLMN (Home PLMN), which is the PLMN that is permanently stored in the UE. Finally, if HPLMN is not available, the UE will select EHPLMN (Equivalent HPLMN), which is the PLMN with the same MCC and MNC as HPLMN.

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:

According to the Huawei SA Networking Product Design Guide ( the downlink data split modes supported on the gNodeB side in the 5G NSA Option 3x architecture are A. MCGONLY: only split to the MCG and D. SCGANDMCG: dynamic data split. The MCGONLY mode is used when all the UE data must be sent to the same MCG, while the SCGANDMCG: dynamic data split mode is used when the data is split between multiple SCGs and MCGs.
