A method for cross carrier scheduling can include: determining that a candidate DCI for a UE schedules a DG PDSCH that at least partially overlaps an SPS PDSCH for the UE, wherein the DCI is configured to be transmitted on a first CC having a first SCS, and the DG PDSCH is configured for transmission on a second CC having a second SCS different from the first SCS; determining a timing gap based on the smallest of the first SCS and the second SCS; determining that an available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; cancelling the SPS PDSCH responsive to determining that the available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; and transmitting the DCI to the UE.
