Without BW information UE cannot decode other channels. Like total no of PDCCH CCE is based on the PCFICH and BW. Also BW says no of RB's used for DL allocation. Based on BW information UE will get to know the starting RB's and ending RB's.

When an UE switch on, first it synchronizes (PSS and SSS) with cell and start reading system information. My question is what UE does after getting system bandwidth information from MIB ? What is the significance of this for an UE ? Does UE take different actions based on cell bandwidth ?
