LTE Initial Access - System Message Reception

LTE Initial Access - System Message Reception:

After successful cell search, the next step is getting the system information.
The UE configures the logical Broadcast Control Channel (BCCH) via the Broadcast Channel (BCH) and maps it to the Physical Broadcast Channel (PBCH) to be able to decode the Master Information Block (MIB).
The MIB contains indispensable system information for the UE operation.
MIB includes information about the number of available resource blocks, configuration of the Physical HARQ Indicator Channel (PHICH) and the System Frame Number (SFN). The MIB is transmitted in the first four OFDM symbols in the second time slot of sub-frame 0 and is repeated every fourth frame.
