MIB Decoding:
i) DL Bandwidth, Number of Transmit Antenna, Reference Signal Transmit Power
ii) System Frame Number (SFN)
iii) PHICH Configurationiv) Transmit every 40 ms(used for HARQ ACK/NACK)
iv)The MIB uses a fixed schedule with a periodicity of 40 ms and repetitions made within 40 ms.
v)The first transmission ofthe MIB is scheduled in subframe #0 of radio frames for which the SFN mod 4 = 0, and repetitions are scheduled insubframe #0 of all other radio frames.

Query: How does the UE read MIB?
- The MIB is transmitted on physical channel (BCCH-BCH-PBCH) and it always occupies the central 72 sub carriers in the Frequency domain irrespective of the channel bandwidth.
- The first transmission of the MIB is scheduled in sub-frame number 0 of radio frames for which the SFN mod 4 = 0
- repetitions are scheduled in sub-frame 0 of all other radio frames
