1. A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:

  • configuring a Secondary Cell (SCell) with a Physical Uplink Control Channel (PUCCH) resource;

    receiving Radio Resource Control (RRC) signaling informing the UE that the PUCCH resource is released from the SCell, wherein the RRC signaling includes a value of a deactivation timer associated with the SCell;

    setting the deactivation timer associated with the SCell to the value included in the RRC signaling;

    releasing the PUCCH resource from the SCell according to the RRC signaling;

    re-activating the SCell;

    starting the deactivation timer associated with the SCell; and

    triggering Power Headroom Reporting (PHR) of the SCell after reactivation of the SCell.
