Question

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?

Answer 1

In case of sysinfo modification or cmas, etws notification eNB should schedule the paging at all paging occasion/paging subframe during the system modification period. because this paging is not only indented to one or few UE. Any UE in idle or connected mode need to know these indication so that UE can read the updated sysinfo or ETWS/cmas notification if UE is capable.
