After the PA reconfiguration of a 5G base station in SA networking, it is necessary to check whether cell-related alarms are reported, whether the 5G cell services are normal, and whether the PCI on the NR side has taken effect on the NE. These checks are necessary to ensure that the reconfiguration has been successful.

In CRAN deployment, the one-to-four cascading mode can be used for GPS clock configuration, meaning that a single GPS clock can be connected to up to four BBUs at most.

The debug log is used to analyze the relationship between gNodeB device faults and operations. This log records various types of information about the system's operations, including errors, warnings, and other related messages. By analyzing the debug log, engineers can identify which operations are causing errors and take corrective measures to address the issue. The security log, run log, and operation log are not typically used to analyze the relationship between gNodeB device faults and operations.

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.

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/

The statement A is incorrect. The larger the subcarrier spacing [1], the shorter the symbol duration on each subcarrier, not the larger number of symbols. Statement B is also incorrect. The larger the subcarrier spacing [1], the larger the CP length and the more suitable it becomes for wide coverage. Statement C is correct. The smaller the subcarrier spacing, the lower the power spectral density. Statement D is incorrect. The larger the subcarrier spacing [1], the shorter the slot length.
