LTE system information blocks

Postby beginner » 23 Feb 2016, 11:04

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 between same RAT base stations(GSM BTS1 to GSM BTS2) and different RAT base stations(GSM to WCDMA or GSM to LTE or between WCDMA to LTE etc.) . Covers E-UTRA and other RATs as mentioned

SIB5
Carries Inter Frequency Neighbors(on different frequency); carries E-UTRA LTE frequencies, other neighbor cell frequencies from other RATs. 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

SIB7
carries GSM neighboursinformation 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 eNodeBIdentifier)

SIB10
carries ETWS prim. notification

SIB11
carries ETWS sec. notification
