Reception or transmission of physical downlink control channels (PDCCH) associated with a master node (MN) or with a secondary node (SN) involve an indication for a first number of cells Ncells,MCGcap and for a second number of cells Ncells,SCGcap. A first total number of PDCCH candidates is determined on Ncells,MCGDL,μ cells of the MN over a time period according to Ncells,MCGcap and a second total number of PDCCH candidates is determined on Ncells,SCGDL,μ cells of the SN over the time period according to Ncells,SCGcap. μ is a subcarrier spacing (SCS) configuration for an active bandwidth part (BWP) on each of the Ncells,MCGDL,μ cells or Ncells,SCGDL,μ cells.
