H35-481_V2.0 HCIP-5G-RAN V2.0 Exam Questions and Answers

According to Huawei official documentation, When the RUN indicator of an AAU is blinking green (on for 1s and off for 1s), it means that the software is being loaded to the board, or the board is not started.

According to the Huawei official documentation, a gNodeB supports up to 4 OM channels at most. These channels can be used to monitor and manage the gNodeB remotely. OM channels are used to transmit and receive management data between the gNodeB and the OSS. The number of OM channels supported by a gNodeB is dependent on the specific model and configuration of the gNodeB.

The theoretically noise (dBm) over the air interface should be -116 dBm. The noise is calculated by subtracting the noise figure of the receiver from the thermal noise floor, which is determined by the subcarrier spacing and the bandwidth of each Resource Block (RB). In this case, the subcarrier spacing is 30 kHz and the bandwidth of each RB is 360 kHz, so the thermal noise floor is -116 dBm.

BWP (Bandwidth Part) is related to the time-frequency position of the PRACH used by the UE in the contention-based random access procedure. According to the official Huawei documentation, the BWP consists of one or more contiguous frequency sub-bands of the PRACH and defines the time-frequency position of the PRACH used by the UE.

According to Huawei's documentation, the STR CROSFEEDTST command can be used to check for crossed feeder connections of an AAU. It is used to check whether the feeder cables of different antennas are connected to the correct ports. The command can be executed on the AAU to detect crossed feeder connections and ensure that the feeder cables are connected to the correct ports.
