1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
receiving configuration information regarding a cross carrier scheduling related to scheduling information for data on a primary cell received from a secondary cell; and
monitoring a physical downlink control channel (PDCCH) related to the scheduling information, wherein the PDCCH is available to be monitored in one of: (i) a first active downlink bandwidth part (DL BWP) in the primary cell or (ii) a second active DL BWP in the secondary cell;
wherein a first subcarrier spacing (SCS) for the first active DL BWP is smaller than a second SCS for the second active DL BWP, and
wherein, for monitoring the PDCCH, (i) a total number of PDCCH candidates per slot on the first active DL BWP, (ii) a total number of non-overlapped control channel elements (CCEs) per slot on the first active DL BWP, (iii) a total number of PDCCH candidates per slot on the second active DL BWP and (iv) a total number of CCEs per slot on the second active DL BWP are determined based on a first certain number of downlink cells related to the first SCS.
