Take an example:

  • UE camps to an LTE network let's say LTE B66. Network sends RRC reconfiguration to measure the neighbor cells.
  • UE scans & sends measurement report reporting neighbor cells. Now network sent RRC reconfiguration (handover command) to another cell which has good signal conditions than the serving cell.

Based on my understanding after decoding the RRC reconfiguration UE will know the target PCI, RACH Information.

Also I'm not sure if we decode mib & sib 1 of target cell during HO process ?

If we do not decode the target cell mib & sib 1 then how do we perform downlink synchronization i.e. how does UE get to know what is the SFN ?According to me we get System Frame Number decoded in Master Information Block (MIB) in Physical Broadcast channel (PBCH)

Can anyone point me out:

  • [1] How/When does UE get to know what is the SFN during HO process ?
  • [2] Do we actually decode mib & sib 1 of target cell during HO process ?

Thanks.
