LTE: How does a lte UE decode MIB ?

Question

A cell may be configured with different frequency even with different bandwidth. In such environment, how does a lte ue decode MIB ?

Answer 1

i) Search the center frequency by searching DC part
ii) Depending on UE PHY protocol stack implementation, UE may measure RSSI and determine whether it goes to next step or not.
iii) Decode BCH which occupies 62 subcarriers (6 RBs) at the center frequency.
iv) BCH tells the frequency information of the system (eg. System Frequency Bandwidth)

Comments

Does the Ue search for every frequency of LTE one by one or any other mechanism it use ?
