What is SIB in LTE?

System Information Blocks in LTE, SIBs carry relevant information for the UE, which helps UE to access a cell, perform cell re-selection, information related to INTRA-frequency, INTER-frequency, and INTER-RAT cell selections. In LTE there are 13 types of SIBs.

What is SIB and MIB in LTE?

In LTE there are several versions of System Information Blocks (SIB) and Master Information Block (MIB), each of them carries different information to UE. MIB message: is broadcasted on PBCH. There is only one type of MIB. SIB messages: are sent on PDSCH through RRC layer: •

What is SIB decoding?

System Information Block (SIB 1)

SIB 1 can be decoded from MIB once every 10 ms radio-frame. A SIB 1 is sent whenever SFN mod 8 = 0. Each transmission of SIB 1 is followed by 3 transmissions when SFN mod 2 = 0. This transmission timing for SIB 1 is shown below. SIB1 Periodicity.

Which channel carries SIB in LTE?

The SIBs are transmitted in the broadcast control channel (BCCH) logical channel. Generally, BCCH messages are carried on the downlink shared channel (DL-SCH) and transmitted on the physical downlink shared channel (PDSCH).
