NR RAN Zero to Hero Guide Level 1- Assessment

What are the benefits with a flexible numerology?

• a)Higher throughput

• b)Possible to combat phase noise at higher frequencies

• c)We do not need SC-FDMA

What is true about the control plane and user plane in Stand-alone (SA) and Non-standalone (NSA) 5G NR?

• For NSA Control Plane is handled only by LTE

• . For SA Control Plane is handled only by NR

• For NSA User Plane is handled only by LTE

•  For SA User Plane is handled only by NR

What is the maximum bandwidth of a single high band carrier in 5G NR?

• 100 MHz

• 200 MHz

• 400 MHz

• 800 MHz

Why do we need a numerology with larger subcarrier spacing at higher carrier frequencies?

• a)To reduce the impact of ISI

• b) To avoid an excessive number of subcarriers in the IFFT/FFT

• c) To reduce the impact of phase noise

• d)To increase the data rate

A subframe

• Consists of a number of slots or mini-slots

• Always consists of two slots

• Has a duration of 1 ms, regardless of numerology

• Has a duration that varies with the numerology
