MIB : Carries PLMN identity and reference to other SIBs and SB
SB : Scheduling infor of SIBs
SIB1 : NAS Information. UE Timers and counters to be used in RRC Idle & Connected State
SIB2: List of URA Identities
SIB3: Parameters for Cell Selection and Reselection
SIB4: Same as SIB3 but used in Connected State
SIB5: Configuration parameters of common physical channels in a cell. PCH and PICH Info (CPCH)
SIB6: Configuration of Common and Shared physical channel
SIB7: Contains fast changing UL interface params and dynamic. As this is changs often so controlled by timer
SIB8: Used in FDD . Static CPCH info of cell. Used in Connected mode only
SIB9: CPCH info. As it changed often, controlled by timers connected mode only.
SIB10 : DRAC Procedure, used when CELL_DCH controlled by timer
SIB11 : Measurement control information to be used in CELL
SIB12: Same as SIB11 but used in connected mode only
SIB13: For ANSI-41 . It also has 4 associated sibs 13.1 to 13.4. Reference to subblocks. Used when System is ANSI-41.
SIB14: Parameters for common and dedicated physicall DPCH UL outer loop power control info for TDD
SIB15: Assistance info for UE positioning. Used to reduce signalling by position. 15.1 to 15.5 sub sibs.
SIB16: Predefined channel conf. used while hand over. Radio Bearer transport channel, physical channel params to be stored by UE in idle/connected mode. Several occurances but UE doesnot bother.
SIB17: Shared channel info fo rTDD only
SIB18: PLMN Identities of neighbouring cells. Used in Shared Access N/w with the cell reselection process
