Hello Everyone,

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

Scenario:

  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.

Query:
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 ?
