Abstract

The present invention is directed to a method and an apparatus used for in a wireless communication system. Specifically, the present invention is directed to a method of controlling cell activity and an apparatus therefore, in which the method comprises: receiving a signal including an identifier and a timer value, wherein the identifier identifies a corresponding TAG and the timer value is used for cell deactivation of the corresponding TAG; and applying the received timer value to all cells belonging to the corresponding TAG.

Claims

1. A method of controlling cell activity at a user equipment in a wireless communication system, the method comprising:

receiving a signal including an identifier and a timer value, wherein the identifier identifies a corresponding Timing Advance Group (TAG) and the timer value is used for cell deactivation of the corresponding TAG; and

applying the received timer value to all cells belonging to the corresponding TAG.

2. The method of claim 1, wherein the identifier is a TAG identifier.

3. The method of claim 1, wherein the identifier is a cell identifier, and the timer value is applied to all cells belonging to the corresponding TAG including a cell indicated by the cell identifier.

4. The method of claim 3, wherein the cell identifier is a secondary cell identifier.

5. The method of claim 1, wherein the signal is a Radio Resource Control (RRC) signal or a Medium Access Control (MAC) signal.

6. The method of claim 1, wherein the corresponding TAG is a secondary TAG.

7. The method of claim 1, wherein a timer value of a first TAG is set to be different from a timer value of a second TAG.

8. A User Equipment (UE) configured to control cell activity in a wireless communication system, the UE comprising:

a radio frequency (RF) module; and

a processor, wherein the processor is configured to;

receive a signal including an identifier and a timer value, wherein the identifier identifies a corresponding Timing Advance Group (TAG) and the timer value is used for cell deactivation of the corresponding TAG, and

apply the received timer value to all cells belonging to the corresponding TAG.

9. The UE of claim 8, wherein the identifier is a TAG identifier.

10. The UE of claim 8, wherein the identifier is a cell identifier, and the timer value is applied to all cells belonging to the corresponding TAG including a cell indicated by the cell identifier.

11. The UE of claim 10, wherein the cell identifier is a secondary cell identifier.

12. The UE of claim 8, wherein the signal is a Radio Resource Control (RRC) signal or a Medium Access Control (MAC) signal.

13. The UE of claim 8, wherein the corresponding TAG is a secondary TAG.

14. The UE of claim 8, wherein a timer value of a first TAG is set to be different from a timer value of a second TAG.
