PDCCH monitoring when both CSS and USS are configured

Hello Everyone,

I have below query regarding PDCCH monitoring when both USS and CSS are configured.


  1. As part of SIB-1 configuration, UE is configured with a common searchSpace. pagingSearchSpace and ra-SearchSpace are set to this common searchSpace.
  2. As part of RRC Setup, UE is configured with UE specific search space.

After RRC setup, when both CSS and USS are configured, should UE monitor for DCI scrambled with C-RNTI in only UE specific searchSpace or both UE specific and common searchSpace ?
