AFAIK periodicity of MIB and SIB are fixed by the specifications.
but why they specified 80ms for sib and 40 ms for mib?

If CELL DOWN is performed with an eNodeB, the RF goes down gradually rather than instantly. Should it re-schedule and broadcast the MIB and SIB messages during that time?

Lets suppose UE has sent mesurementReport to Source eNB and Source eNB respond with rrcConnectionReconfiguration including Target eNB's infor( PCI..etc). My question is whether UE will first sync in DL direction with target eNB and then sends rrcConnectionReconfiguationComplete. Then UE will read MIB and SIB's ?
