H35-580_V2.0 Exam Dumps : HCIA-5G-RNP&RNO V2.0

According to the HCIA-5G V2.0 Exam Outline, cell unavailability due to system faults (specified using N.Cell.Unavail.Dur.System) is caused by factors such as CPRI link faults, board faults, and faults on an RF module’s TX or RX channels, which correspond to options A, C, and D. Blocking cells by using MML commands is not a system fault, but a manual operation, which corresponds to option B.

According to the 5G NR Downlink CSI Reporting, CSI-RS is the channel/signal that is used by the UE to measure and obtain the CQI. CSI-RS stands for Channel State Information Reference Signal, which is a downlink reference signal transmitted by the gNodeB to enable the UE to estimate the channel quality and feedback the CQI to the gNodeB. The CQI is an indicator of how good or bad the channel quality is, and it can be used by the gNodeB to adjust the modulation and coding scheme for data transmission.

According to the Huawei Releases 5G Series Products, Huawei’s AAU5313 and AAU5613 are both RF modules that support 64T64R. The AAU5313 is an ultra-wideband Massive MIMO product that supports both 64T64R and 400 MHz bandwidth on the C-band. The AAU5613 is a BladeAAU Pro product that supports 64T A+P integration on sub-3 GHz bands. The AAU5612 is a BladeAAU product that supports only 32T A+P integration on sub-3 GHz bands. The RRU3939 is not an AAU product but an RRU (Remote Radio Unit) product that supports only 8T8R on sub-3 GHz bands.
