In 5G NR, the Master Information Block (MIB) message is transmitted on the Physical Broadcast Channel (PBCH) and contains information that is used by the UEs to synchronize to the cell and obtain basic system information. The parameters in the NR MIB message that indicate the time-domain position of CORESET 0 are the least significant four bits of PDCCH-configSIBl.

In NSA networking, In self-setup scenarios, the USERPLANEHOST and SCTPHOST objects are unnecessary to configure for a gNodeB. The USERPLANEHOST object is used to configure the IP address of the user plane host, and the SCTPHOST object is used to configure the IP address of the SCTP host. In self-setup scenarios, the gNodeB automatically obtains the IP addresses of the user plane host and SCTP host from the S1-MME or S1-U peer. The USERPLANEPEER and SCTPPEER objects are necessary to configure for a gNodeB in SI self-setup scenarios. They are used to configure the IP address of the user plane peer and SCTP peer, respectively.

During a cell search, a UE uses synchronization signals to synchronize to a cell and obtain basic system information. The synchronization rasters that can be used by a UE during a cell search are:

A. 17.28MHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 5G NR.

B. 1200kHz: This is the synchronization raster that is used for the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) in 4G LTE.

C. 1.44MHz: This is the synchronization raster that is used for the cell-specific reference signal (CRS) in 4G LTE.

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.

Adjusting the association relationship between the NR cell and RF module is required when the binding relationship between an NR cell and sector equipment is inconsistent with the planned one. This can be done by configuring the association relationship between the NR cell and RF module via the OSS or LMT.

The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.

You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.

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.

5G E2E slicing can be used to ensure the QoS and security of smart grid services. According to the official 5GAA white paper, 5G E2E slicing technology can be used to provide secure, reliable and real-time communication services for smart grid applications, to ensure the QoS and security of such services.

the cell-specific reference signal (CRS) that is always sent in LTE cells is not used in NR to reduce interference under light loads and control channel overhead. Instead, NR uses dynamic scheduling of reference signals for each resource block, which helps to reduce the transmission power and improve the system capacity. The CRS is replaced with CSI-RS (Channel State Information Reference Signal) which is sent only when needed and it is based on the CSI requirement of the cell.

The official site for 3GPP specifications is https://www.3gpp.org/specifications . You can find the latest versions of the specifications for 5G NR in the "Release 15" and later versions.

You can refer to the specification 38.211 (Physical channels and modulation) specifically section 7.4 "Cell-specific reference signal (CRS)" and section 7.5 "Channel state information-reference signal (CSI-RS)".

Here is an excerpt from the specification 38.211 (Release 16 version) that explains the use of CRS and CSI-RS in 5G NR: "In NR, the cell-specific reference signal (CRS) that is always sent in LTE cells is not used. Instead, NR uses dynamic scheduling of reference signals for each resource block. This is done to improve system capacity and reduce transmission power. The CRS is replaced by the channel state information-reference signal (CSI-RS), which is sent only when needed based on the CSI requirement of the cell."

The network layer in the transport protocol stack provides functions such as addressing and route selection. It is responsible for finding the best route for data packets to travel from the source to the destination. It also provides logical addressing and packet routing. The network layer does not provide the transmission of binary data flows, MAC forwarding, or physical medium access.

According to the official 3GPP specification, the DCI of NR does not carry PUSCH power control information. It carries scheduling information for the PUSCH and PDSCH and a PMI report. Reference: https://www.3gpp.org/DynaReport/38-series.htm

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.

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.

The PING, TRACERT, CFMTRACE, CFMPING, and UDPECHO commands cannot be executed simultaneously on the same board in a gNodeB. Executing multiple commands at the same time can cause system instability, so it is not recommended to do so.

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.
