System Information are of Two variant : Static(MIB) and Dynamic (SIB)
MIB: Master Information Block
Logical Chennel: BCCH
Transport Channel: BCH/PBCH
Physical Channel: PBCH
SIB: System Information Block
Logical Chennel: BCCH
Transport Channel: BCH/DL-SCH
Physical Channel: PDSCH
Total 11 SIBS (1,2,3,4,5,6,7,8,9,10,11) are there in LTE according the basic release (Release 8).
There are some more inclusioon of SIB's as per the latest release is as below,
