Method and user equipment (UE) are provided for scheduling with multiple cells. In particular, a UE can connect to a plurality of cells in a network. The UE can determine a specific slot for receiving a CSI-RS from a first cell. An index of the specific slot is n+X+L while n is an index of a slot for receiving a DCI from a second cell, X is a slot offset for triggering the CSI-RS and L includes parameters associated with SCSs of the first cell and the second cell. The UE can receive the CSI-RS from the first cell in the specific slot.
