Question: how ue decodes mib in lte?
Answer: Now for a UE to know the 40 millisecond boundary, all it has to find is 4 consecutive system frame numbers that are same. ... So for the best case, if the UE starts decoding the MIB from RF-0 it will see same system frame number for 4 consecutive radio frames and it will understand that RF-0 is the 40 millisecond boundary.
