According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), the MML command used to bind a physical sector to an AAU on a gNodeB is ‘ADD NRLOCELL’.

A. NR downlink slots are used to transmit downlink data and control information, such as channel state information (CSI) and downlink control information (DCI). B. Downlink self-contained slots are also called as "Downlink Shared Channels (DL-SCH) slots", they can be used to transmit downlink data, but also can be used to transmit uplink control information (UCI) and sounding reference signals (SRS) in the downlink direction.

D. The symbols in a slot can be classified as downlink, uplink, or flexible, meaning that the symbols can be used to transmit data in either direction, or to transmit control information.

It's worth noting that the NR slot structure is designed to be flexible and efficient, it allows for a variable slot duration and a variable number of symbols, depending on the subcarrier spacing and the number of resource blocks used. This flexibility is intended to support a wide range of services and traffic types.

End-to-end (E2E) network device update is required for the evolution from 5G Non-Stand-Alone (NSA) networking to Stand-Alone (SA) networking. In 5G NSA networking, the control plane functions are handled by the 4G LTE network, while the user plane functions are handled by the 5G NR network. In contrast, in 5G SA networking, the control plane and user plane functions are handled by the 5G NR network alone. So, to evolve from 5G NSA to 5G SA, all the network devices including Radio Access Network (RAN), Core Network (CN) and Transport Network (TN) need to be updated with 5G SA capable software and hardware.

It is important to note that 5G SA provides more flexibility, control and autonomy for network operation and management, However, it also requires a higher level of complexity and more resources to operate.

The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.

In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.

-"The following frequency locking modes are not supported when the GENEX Probe is used to perform a CPE test: PCI, Cell frequency" in Huawei official website.

PCI (Physical Cell Identity) is related to the frequency-domain position of PBCH DMRSs (Physical Broadcast Channel Demodulation Reference Signals)

The PBCH DMRSs are used to demodulate the Physical Broadcast Channel (PBCH) which contains system information such as the cell identity, system bandwidth, and the downlink carrier frequency.

The PBCH DMRSs are transmitted in the frequency domain, and their position is determined by the Physical Cell Identity (PCI). The PCI is a unique identifier assigned to each cell in the network, and it's used to identify the cell and its system information.

So, the correct answer is B. PCI. It's worth noting that the other parameters you mentioned are also related to the 5G system information and the cell configuration. Cell ID is a unique identifier assigned to each cell, SI-RNTI (System Information RNTI) is a unique identifier assigned to the system information, and Bandwidth is the amount of frequency resources allocated to the cell.
