SIB1 is transmitted over PDSCH channel. Location of SIB1 is find out based on DCI information transmitted over PDCCH channel. UE get to know about PDCCH channel search space based on PCFICH and PHICH. Each cell encode its system information based on identifier i.e SI-RNTI.
With respect to Intra-cell (oneENB multiple cells), each cell will have different PCI's(physical cell identity).
Whether all cells will have same systeminformation(MIB,SIB) or it will differ? OR It is implementation specific?
How MAC will schedule PCCH message with ETWS or Sys info change(for the UEs which are in IDLE)?As RRC donot provide any configurations to MAC (we will provide PCCH config like UE indx val ,nb and Drx for DL data indication but in ETWS we wil not have UE indx val).Is there any other mechanism for MAC to Schedule PCCH message with ETWS notification?
