Dear friend!

After initial cell synchronization is completed, UE reads MIB (Master information block) on PBCH (Physical channel). Broadcast channel is referred as BCH at transport level and BCCH at logical level. MIB composed of downlink channel bandwidth in units of RBs, PHICH duration, PHICH resource and system frame number.

Hello,

Physical Broadcast Channel (PBCH): This physical channel carries system information for UEs requiring to access the network. It only carries what is termed Master Information Block, MIB, messages. The modulation scheme is always QPSK and the information bits are coded and rate matched - the bits are then scrambled using a scrambling sequence specific to the cell to prevent confusion with data from other cells.

The MIB message on the PBCH is mapped onto the central 72 subcarriers or six central resource blocks regardless of the overall system bandwidth. A PBCH message is repeated every 40 ms, i.e. one TTI of PBCH includes four radio frames.

The PBCH transmissions has 14 information bits, 10 spare bits, and 16 CRC bits.

Thanks
