Minimum information for UE to perform blind decoding and obtain the DCI

Hi Experts.

What is the minimum information the UE needs to know to perform blind decoding and obtain the DCI?

I know UE does blind decoding over AL and cces but does it need to know something to do the search?

Coreset and search space.

Are Coreset and SS different things?

Yes a Coreset may have multiple Search Space.
