Answer : D

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

Answer : B

'The RSRP value of the test terminal can be viewed on the GENEX Probe. A RSRP value of between -60dBm and -90dBm indicates good signal quality. Lower values indicate weaker signals, while higher values indicate stronger signals.'

Answer : A, B

1. DM-RS (Demodulation Reference Signals) are transmitted in the frequency domain, they are used to demodulate the downlink data and control channels, and they can be used for cell measurement such as cell identification, cell reselection, and handover. B. CSI-RS (Channel State Information Reference Signals) are also transmitted in the frequency domain, they are used to provide channel state information for downlink data and control channels, and they can be used for cell measurement such as link adaptation, beamforming and interference management.

DM-RS stands for Demodulation Reference Signal and is used for channel estimation in the frequency domain. CSI-RS stands for Channel State Information Reference Signal and is used for channel estimation in the time-frequency domain. PT-RS and SSB are not channels (signals) that can be used for cell measurement in NR.

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

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.
