PBCH Decoding Process
When you power on 5G/NR UE(NR Standalone UE) or When LTE is adding NR Cell as a secondary cell, the first thing happening in UE is the process described below.
i) Search Frequency in which SSB (PSS + SCC + PBCH) is transmitted.
ii) Search PSS ==> By detecting PSS, UE can figure out
iii) Search SSS ==> By detecting SSS, UE can figure out
iii) From and , UE can calculate Physical Cell ID ()
iv) Search PBCH DMRS
==> from PBCH DMRS UE can
v) (based on Channel and Noise estimation) Perform Equalization for PBCH extraction
==> Once this equalization is done properly, UE can
vi) Demodulate PBCH ==> figure out PBCH bits
vi) Decode PBCH ==> Figure out MIB
