In 5G NR, the master information block (MIB) is a control message that is transmitted by the base station on the Physical Broadcast Channel (PBCH). The MIB contains the following information:
1. System frame number: The MIB contains the system frame number (SFN) which is used to identify the current frame in the system.
2. PDCCH ConfigSIB1: The MIB contains the PDCCH (Physical Downlink Control Channel) configuration for the SIB1 (System Information Block 1) which is used to transmit system information to the UE.
3. dmrs-TypeA-Position: The MIB contains the position of the dmrs-TypeA (Diversity and Multiplexing Configuration Reference Signal) which is used to transmit a reference signal for demodulation and channel estimation.

5G can enable smart manufacturing by providing ultra-reliable and low-latency communication, enabling the deployment of various industrial internet of things (IIoT) applications, such as collaborative control between machines. This allows for real-time coordination and control between machines, enabling them to work together in a coordinated way to achieve a common goal, such as increasing production efficiency or reducing downtime. This can help to improve the overall performance of the manufacturing process and upgrade the manufacturing business model.

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.

When a GPS divider is used, the maximum distance between the GPS antenna and the BBU is shortened. This is because the divider splits the signal from the antenna into multiple signals that can be distributed to multiple BBUs, thus reducing the distance between the antenna and the BBUs.

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.
