5G Training Lesson 3

8T8R is

• Passive Antenna System

• Both

• Active Antenna System

• None of the others

32T32R is

• Passive Antenna System

• Active Antenna System

• All the others

• None of the others

More arrays of antennas, lead to:

• Higher coverage

• Less Coverage

• Equal Coverage

• All the others

Active antenna system allow:

• 2D Beamforming

• No Beamforming

• 3D Beamforming

• Only SSB Beamforming

What is the maximum 3GPP allowed donwlink MIMO Layers for SU-MIMO ?

• 12

• 4

• 8

• 2

FR1 uses

• Analogue beamforming

• Digital beamforming

• Both

TDD PDSCH beamforming can be done through:

• SSB beams (CSI-RS beam refinement)

• CSI-RS CM grid of beams using PMI Code-Book

• UL-SRS reciprocity

• all are correct

When the Bearer is added to the UE through 5G gNB, we called:

• MCG Addition

• SCG Addition

• LTE Bearer

• 5G Bearer

When the UE move between two different gNBs, is called:

• LTE handover

• MCG Handover

• SCG Change

• all are correct

For the Active Antenna Systems, normally one PA could feed:

• 1 antenna

• 2 antennas

• 2,3 or 4 antennas

• none are correct
