LTE: How does a lte UE decode MIB ?

0 votes

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

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)

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

Can you, please explain what happens for the common channels? The PSS/SSS and PBCH have a fix position in time-frequency domain so in the area between the sectors we will have those REs (resource elements) and RBs (resource block) that are allocated to them that will interfere.
Also, can you explain how it is possible to decode the signals when the UE measures a negative SINR?

I mean to say, why does MIB transmit only on sub frame 0 not on other sub frames of same radio frame ?
