Method and apparatus for supporting carrier aggregation
First Claim
1. A method of performing power management at a user equipment (UE) in a wireless communication system, the method comprising:
- configuring, by the UE, a Discontinuous Reception (DRX) cycle, the DRX cycle including a DRX ON duration and a DRX opportunity,wherein the same DRX ON duration is applied to all of two or more activated component carriers, the two or more activated component carrier including a primary component carrier and at least one activated non-primary component carrier assigned to the UE; and
performing, by the UE, Physical Downlink Control CHannel (PDCCH) monitoring for each of the two or more activated component carriers during the DRX ON duration of every DRX cycle,wherein non-primary component carrier activation/deactivation is indicated using a field of Layer 1 (L1) or Layer 2 (L2) control information, the field having a fixed bit size regardless of a number of configured component carriers.

Abstract
The present invention relates to a method and to an apparatus for supporting carrier aggregation. More particularly, the present invention relates to a method for enabling user equipment to receive a signal from a base station in a wireless communication system which supports carrier aggregation, wherein said the method comprises the steps of: setting a first component carrier to a paused state; receiving state change information for the first component carrier via the second component carrier during the paused state of the first component carrier; and monitoring a control channel via the first component carrier if the state change information indicates a predetermined value. The present invention also relates to an apparatus for the method.
