MIB Carries physical layer information of LTE cell which in turn help receive further SIs, i.e. system bandwidth
SIB1 Contains information regarding whether or not UE is allowed to access the LTE cell. It also defines the scheduling of the other SIBs. carries cell ID, MCC, MNC, TAC, SIB mapping.
SIB2 Carries common channel as well as shared channel information. It also carries RRC, uplink power control, preamble power ramping, uplink Cyclic Prefix Length, sub-frame hopping, uplink EARFCN
SIB3 carries cell re-selection information as well as Intra frequency cell re-selection information
SIB4 carries Intra Frequency Neighbors(on same frequency); carries serving cell and neighbor cell frequencies required for cell reselection as well handover
SIB5 Carries Inter Frequency Neighbors(on different frequency); carries E-UTRA LTE frequencies, The purpose is cell reselection and handover.
SIB6 carries WCDMA neighbors information i.e. carries serving UTRA and neighbor cell frequencies useful for cell re-selection and handover
SIB7 carries GSM neighbours information i.e. Carries GERAN frequencies as well as GERAN neighbor cell frequencies. It is used for cell re-selection as well as handover purpose.
SIB8 carries CDMA-2000 EVDO frequencies, CDMA-2000 neighbor cell frequencies.
SIB9 carries HNBID (Home eNodeB Identifier)
SIB10 carries ETWS prim. notification
SIB11 carries ETWS sec. notification
SIB-12 Commercial Mobile Alert Service (CMAS) information.
