Most Recent Huawei H35-481_V2.0 Exam Questions & Answers

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.

According to Huawei's 5G AAU Product Brochure, a 64T64R AAU typically has a maximum output power of 40W. This power is split between the 64 transmitters, so each transmitter has an output power of 0.625W. The output power of an AAU can be adjusted depending on the specific requirements.

According to Huawei official documentation, using the MAE-Deployment (radio network planning data file) method is recommended for modifying the cell bandwidths across the entire network during gNodeB data reconfiguration. This method allows for the efficient and accurate modification of cell bandwidths by using a radio network planning data file to update the configuration of multiple gNodeBs at once.

SCTP tracing result is not required to diagnose a low Internet access rate for a user. User performance testing can be used to collect information such as BLER (Block Error Rate) monitoring result, downlink RSRP (Reference Signal Received Power) monitoring result, and MCS (Modulation and Coding Scheme) count monitoring result. However, SCTP (Stream Control Transmission Protocol) tracing result is not required to diagnose a low Internet access rate. Reference: https://www.aricent.com/blog/user-performance-testing-for-5g/
