The GUI configuration mode in MAE-Deployment can be used to configure parameters in an MO and reconfigure a single NE. It cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs. According to the Huawei official documentation, "The GUI configuration mode can be used to configure parameters in an MO and reconfigure a single NE. However, it cannot be used to configure parameters in multiple MOs or to batch reconfigure multiple NEs."

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 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."

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.

When the main control board of a gNodeB is replaced, the Equipment Serial Number (ESN) of the gNodeB also changes. The ESN is a unique identifier of the gNodeB that is programmed into the main control board and is used to identify the specific gNodeB in the network. So when the main control board is replaced, the ESN also changes.

The UBBP board is added to the base station when it is reset, and you need to log in to the LMT again in order to access the new UBBP board. The UBBP board is used for configuration, monitoring, and maintenance of the base station.

According to Huawei's official documentation, when the UBBP (Universal Baseband Processing) board is added, the base station is reset and you need to log in to the LMT (Local Management Terminal) again. The addition of other boards (OUMPT, UPEU, UEIU) may not require a reset and re-login.

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

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.
