P-SS(Primary Synchronization Signal)
Mapped to 72 active sub carriers(6 resource blocks), centered around the DC subcarrier in slot 0 and slot 10.
Cell ID Detection and System Information Detection



i) Frequency Aquisition

ii) Primary Sync Signal Aquisition (Slot Timing Aquired, Secondary Sync Signal Scrambling Code Aquired)

iii) Secondary Sync Signal Aquisition (Frame timing Aquired, Cell Group ID sequence aquired)

iv) with PSS and SSS, Cell ID can be calculated

v) with Cell ID, Reference Signal Location is detected

vi) If Reference Signal Location is properly decoded, PBCH (MIB) can be detected

vii) From MIB, SFN and System BW can be detected

viii) Decode PCFICH and detect how many symbols are allocated for PDCCH.

ix) Decode DCI for SIB1 from PDCCH

x) Decode SIB1 and get the scheduling information for other SIBs

xi) Decode SIBs (other than SIB1)
