9. A method for a user equipment (UE) enabled for carrier-aggregation communication with primary cells (PCells) and secondary cells (SCells), comprising:
receiving a radio resource control (RRC) signaling from a base station to add a secondary cell (SCell), wherein the RRC signaling comprises a configuration of one or more bandwidth parts (BWPs) associated with the SCell, including a default BWP;
activating a BWP for the SCell, wherein the activated BWP is different from the default BWP;
starting a BWP timer for the BWP;
stopping the BWP timer upon deactivation of the SCell; and
switching the BWP for the SCell to the default BWP when the SCell is re-activated.
