A method and apparatus are disclosed to improve inter-band carrier aggregation (CA) in a UE (User Equipment) in TDD (Time Division Duplex) mode. In one embodiment, the method includes connecting the UE with a PCell (Primary Serving Cell). The method further includes configuring the UE with at least one SCell (Secondary Serving Cell), among which at least one SCell is deactivated, wherein TDD UL-DL (Uplink-Downlink) configurations of the PCell and the at least one SCell may be different. The method also includes taking a TDD UL-DL configuration of an activated serving cell into consideration for defining consecutive PDCCH (Physical Downlink Control Channel) subframes of a drx-InactivityTimer, and not taking a TDD UL-DL configuration of a deactivated serving cell into consideration.
