Method for de-configuring a cell from PUCCH resource in a carrier aggregation system and a device therefor
First Claim
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.

Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for de-configuring a cell from PUCCH resource in a carrier aggregation system, the method comprising: configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving a Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell with the PUCCH resource; de-configuring the PUCCH resource from the SCell according to the RRC signaling; re-activating the SCell; and starting a SCell deactivation timer associated with the SCell.

5. A User Equipment (UE) operating in a wireless communication system, the UE comprising:
-
a transmitter and receiver; and a processor, operatively connected to the transmitter and receiver, wherein the processor is configured to configure a Secondary Cell (SCell) with a Physical Uplink Control Channel (PUCCH) resource, to control the receiver to receive 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, to set the deactivation timer associated with the SCell to the value of the RRC signaling, to release the PUCCH resource from the SCell according to the RRC signaling, to re-activate the SCell, to start the deactivation timer associated with the SCell, and to trigger Power Headroom Reporting (PHR) of the SCell after reactivation of the SCell. - View Dependent Claims (6, 7, 8)
