Pass the Huawei HCIP-5G-RAN H35-481_V2.0 Questions and answers with CertsForce

A. High signal attenuation is caused due to improper GPS remote distance. B. The antenna feeder between the base station and the GPS is faulty, for example, the cable is disconnected. C. The GPS is not installed in the correct position, and the number of locked satellites is less than 4. D. The GPS satellite card Is faulty.

Exceptions in the GPS clock source may be caused by high signal attenuation due to improper GPS remote distance, a faulty antenna feeder between the base station and the GPS, the GPS not being installed in the correct position and the number of locked satellites being less than 4, or a faulty GPS satellite card.

According to Huawei's BTS5900 Product Brochure, PnP (Plug and Play) mode can be used for local data configuration if the configuration data of a new BTS5900 base station cannot be loaded remotely. In PnP mode, the BTS5900 automatically obtains the IP address and configuration data from the OMC or other device through DHCP. The BTS5900 also supports manual configuration of the IP address and configuration data.

According to Huawei official documentation, B. Batch reconfiguration of NEs is a scenario that can be performed using the radio data planning file in the MAE-Deployment. The radio data planning file can be used to perform batch reconfiguration of NEs, such as the configuration of multiple NEs in a batch. The radio data planning file can be used to import data, perform parameter configuration, and export the configuration results. The other options are not performed using the radio data planning file in the MAE-Deployment.

Increased GP overhead due to frequent uplink-downlink switching. Self-contained slots are designed to reduce the round-trip time (RTT) by providing faster downlink hybrid automatic repeat request (HARQ) feedback and UL data scheduling, as well as prolonged sounding reference signal (SRS) transmission periods to track fast channel changes and improve MIMO performance. However, they do not involve increased GP overhead due to frequent uplink-downlink switching. High requirements on latency of terminal hardware processing may be involved, depending on the implementation.

MEC (Mobile Edge Computing) is a network technology that enables the deployment of computing and storage resources at the edge of the network, closer to the end-users. This can significantly reduce the latency for various applications, such as IoT, AR/VR and IoV. By moving the computing and storage resources closer to the end-users, the data can be processed and stored closer to the source, reducing the time and distance that the data needs to travel. This can reduce the overall latency and improve the user experience.

According to the official GSMA white paper on 5G and IoV, MEC can reduce latency by bringing computing resources closer to the edges of the network. This can be particularly beneficial for IoV applications, which require low latency and high reliability. Additionally, NFV (Network Function Virtualization), Massive MIMO (Multiple Input Multiple Output) and SDN (Software Defined Networking) can also be used to improve performance and reduce latency in 5G networks.

In Non-standalone (NSA) networking, the downlink peak rate of a CPE is affected by various factors, such as the downlink transmit power of the NR base station, the CPE location, the quality of the radio channel, and the configuration of the network. -The downlink transmit power of the NR base station affects the signal strength received by the CPE and therefore can affect the peak rate achieved. -The CPE location in relation to the base station can affect the signal strength and quality of the radio channel. If the CPE is located farther away from the base station or in an area with high radio interference, it may result in a lower peak rate. -Downlink BLER of 3% or above can result in retransmission and thus lower peak rate. -Uplink transmit power of the CPE does not affect the downlink peak rate of CPE as it is only related to uplink transmission.

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.

In a gNodeB, the time information is synchronized from the OSS using the Network Time Protocol (NTP). The ADD NTPC command is used to configure the IP address of the NTP server, which is the time server that the gNodeB synchronizes with. This command is used to specify the IP address of the NTP server, the NTP version, and other parameters related to time synchronization.
