Answer : A, C

1. RSRP (Reference Signal Received Power) is the power level of the reference signals received from the cell, it is used to measure the strength of the signal from the cell, and it is an important parameter for cell selection and handover decisions. C. PCI (Physical Cell Identity) is a unique identifier assigned to each cell in the network, it is used to identify the cell and its system information.

Answer : B

5G inherits the frame structure of 4G, but the slot length can be adjusted based on different subcarrier spacings (SCSs). The 5G slot length can be adjusted from 0.25ms to 1ms, with each slot containing one or more symbols.

The shorter the slot length, the higher the frequency and the less the coverage, but it allows for more efficient use of resources and higher data rates. The longer the slot length, the lower the frequency, the better the coverage, but it's less efficient in terms of resource usage and data rate.

So, the correct answer is B. 10ms, is not a 5G slot length. It's worth noting that the 5G standard defines several slot lengths, and the choice of slot length depends on the specific use case and the requirements of the service being supported.

Answer : A, C, D

NAS (Non-Access Stratum) procedure management in 5G involves three specific actions: registration management, session management, and RRC connection setup. Registration management involves sending and receiving of NAS messages related to the establishment of user-network connections, such as attach and detach procedures. Session management involves sending and receiving of NAS messages related to the management of user session related information, such as security context management. RRC connection setup involves sending and receiving of NAS messages related to the establishment, modification, and release of RRC connections. RRC reestablishment is not involved in NAS procedure management in 5G.

Answer : B

On the 5G RAN side, Service Slicing is implemented using a Base Band Unit (BBU). A BBU is a device that performs baseband processing functions, such as modulation, demodulation, and encoding/decoding of signals. It is also responsible for the connection to the core network and the management of the radio resources. In 5G, BBU is a key component to support service slicing, where different services can be assigned different slices of the network resources, such as bandwidth, power, and quality of service. This allows for more efficient use of resources and better management of different types of traffic, such as broadband and low latency services.

Answer : B

The Sl-U interface is a signaling interface between the 5G CN and the 5G RAN in NSA networking. It uses the SCTP (Stream Control Transmission Protocol) to transport the signaling messages between the 5G CN and the 5G RAN.

The DSP SCTPLNK command can be used to check the status of the SCTP links between the 5G CN and the 5G RAN, it can show the SCTP link status, local and peer IP address, local and peer port number, association status, and more.
