[Dive into 5G] Downlink Physical Channels - Introduction to Common Channels:
1 Purpose
This document answers the following questions:
Why is synchronization signal and PBCH block (SSB) introduced?
How is the time-frequency structure of the SSB designed and defined?
Why is the SSB's frequency-domain position not at the center of the carrier like in LTE?
Why is beamforming performed for the SSB?
How are SSB beams transmitted?
