The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network

"The distance between the CPE and the gNodeB should be greater than 10m to ensure that the test results are accurate and reliable."

According to Huawei's official documentation, the purpose of replaying logfiles is to reproduce the test process, and the GENEX Probe can work without a license in this case. This allows users to test the results of previous tests and compare them with new test results, which is useful for troubleshooting and network optimization.

An NR CQI value represents a coding scheme and coding efficiency, and they are reported in the form of 8 bits by a UE. According to the official Huawei documentation, "The 8-bit long CQI value maps to a coding scheme and coding efficiency that can be used for Transport Block (TB) size selection."

CQI (channel quality indicator) is a value that represents the channel quality of the wireless link between a UE (user equipment) and an eNodeB (base station) in an NR (New Radio) network. The UE reports the CQI value to the eNodeB, which uses it to determine the optimal coding scheme and modulation for the downlink transmissions to that UE.

The CQI value is reported by UE to the eNodeB, it's a value that indicates the channel quality of the link between the UE and the eNodeB. The CQI value is encoded in 8 bits, which allows for a total of 256 different CQI values.

The imbalance between uplink and downlink coverage in C-band is not fixed, it varies depending on the network configuration, location, and other factors. Generally speaking, it's hard to provide an exact number for this imbalance, as it depends on the specific network conditions and the equipment used.

However, a common practice is to use more power in downlink than uplink, this is due to the fact that downlink is more sensitive to path loss than uplink, and also because the downlink signal is intended to cover a larger area than the uplink. Therefore, the imbalance is commonly in the range of 3 to 6 dB, and it's more likely to be at the lower end of that range. So, the correct answer is B. 3dB It's worth noting that the C-band is not the most popular frequency band for 5G network deployment, it's just one of the many frequency bands that are being used for 5G deployment, and the most popular frequency bands for 5G deployment vary depending on the country, region, and operator.

According to the official Huawei documentation, the first message sent by a gNodeB to an AMF is NGAP_INIT_UE_MSG. This message is used to initiate a connection between the gNodeB and AMF.

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), the downlink data split modes supported on the gNodeB side in the 5G NSA Option 3x architecture are A. MCGONLY: only split to the MCG and D. SCGANDMCG: dynamic data split. The MCGONLY mode is used when all the UE data must be sent to the same MCG, while the SCGANDMCG: dynamic data split mode is used when the data is split between multiple SCGs and MCGs.

The maximum number of PCIs (Physical Cell Identifiers) supported by a 5G network is 1008. This is specified in 3GPP 5G standard TS 38.211, which states that the maximum number of PCIs that a 5G network can support is 1008.

In 5G, each cell is assigned a unique identifier called the PCI (Physical Cell Identity). The PCI is used to identify the cell and its system information, and it is used for various purposes such as cell selection, handover, and interference management.

According to 3GPP specifications, the maximum number of PCIs that can be supported by a 5G network is 1008, which allows for a large number of cells to be deployed in a network. However, the actual number of PCIs used in a network will depend on the specific deployment scenario, the network architecture, and the capacity requirements of the network.

"The Mobile Country Code (MCC) and Mobile Network Code (MNC) information added on the gNodeB must be consistent with the PLMN information on the core network."

A. Site deployment list: A document that provides information about the location and basic configuration of the gNodeB, including the site name, coordinates, azimuth, and antenna type. B. Data configuration file of the base station: A file that contains the detailed configuration information of the gNodeB, such as IP address, system parameters, and software version. It is used to configure the gNodeB remotely. C. Base station software package of the target version: A software package that contains the software version that needs to be installed on the gNodeB. D. Base station license: A license file that is required to activate and use the gNodeB.

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), after the NR base station commissioning is complete and before services go online, the NE status must be set to ‘Normal’.

According to Huawei's official documentation, gNodeBs send TPC (Transmit Power Control) commands to UEs over PDCCHs to control the transmit power of PUCCH (Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel).
