Abstract
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource; receiving an Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell, wherein the RRC signaling includes an indication which indicates whether the UE activates or deactivates the SCell from which PUCCH resource is de-configured; de-configuring the PUCCH resource from the SCell; and activating or de-activating the SCell according to the indication after the UE de-configures PUCCH from the SCell.
Claims19
A method for a User Equipment (UE) operating in a wireless communication system, the method comprising:
- configuring a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource;
- receiving an Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell, wherein the RRC signaling includes an indication which indicates whether the UE activates or deactivates the SCell from which PUCCH resource is de-configured;
- de-configuring the PUCCH resource from the SCell;
- and
- activating or de-activating the SCell according to the indication after the UE de-configures PUCCH from the SCell.
A User Equipment (UE) operating in a wireless communication system, the UE comprising:
- a Radio Frequency (RF) module;
- and
- a processor configure to control the RF module,
- wherein the processor is configured to configure a Secondary Cell (SCell) with Physical Uplink Control Channel (PUCCH) resource, to receive a Radio Resource Control (RRC) signaling indicating that the PUCCH resource is de-configured from the SCell, wherein the RRC signaling includes an indication which indicates whether the UE activates or deactivates the SCell from which PUCCH resource is de-configured, to de-configure the PUCCH resource from the SCell, and to activate or de-activate the SCell according to the indication after the UE de-configures PUCCH from the SCell.
