In a 5G NR SA setup, I have configured CORESET0 starting from RB1 for SIB1 scheduling (Type0-PDCCH CSS) and Common CORESET starting from RB6 for RAR (Msg2) scheduling (Type1-PDCCH CSS). The UE successfully decodes SIB1 and the DCI for Msg2 but fails to decode the PDSCH carrying Msg2. I have tried scheduling the PDSCH starting from both CRB0 and CRB6 (aligned with Common CORESET), but both attempts failed.
However, the UE operates normally when both CORESET0 and Common CORESET are configured to start from RB0. To enable the UE to function correctly with CORESET0 starting from RB1 and Common CORESET starting from RB6, what specific configurations or parameters should I verify or adjust?
