1. A method for supporting a carrier aggregation group in a wireless communication system supporting multiple carriers, the method performed by a wireless device and comprising:
- receiving a radio resource control (RRC) configuration message including a first parameter related to one or more serving cells from a macro cell and a second parameter related to one or more serving cells from a small cell; and
configuring two or more carrier aggregation groups (CAGs) based on the first parameter and the second parameter,wherein a medium access control (MAC) main configuration is configured independently per each CAG of the two or more CAGs,wherein the MAC main configuration includes a CAG identification (ID) for the configuration of two or more CAGs,wherein a release, an addition or a modification of a secondary cell (SCell) in a first CAG of the two or more CAGs is applied in accordance with a first parameter related to a common SCell radio resource configuration and a second parameter related to a dedicated SCell radio resource configuration,wherein the first CAG of the two or more CAGs is a group of one or more serving cells employing carrier aggregation,wherein the RRC configuration message is used to modify an RRC connection between the wireless device and a eNodeB (eNB), andwherein a primary serving cell (PCell) for each CAG of the two or more CAGs is configured independently from each other.

Abstract
A method for and apparatus for supporting a carrier aggregation group in a wireless communication system supporting multiple carriers is provided. A wireless device receives a RRC configuration signal including one or more serving cells from a macro cell and a RRC configuration signal including one or more serving cells from a small cell, and configures at least two carrier aggregation group (CAG)s based on the RRC configuration signal each. And, this invention includes that cell planning for multi-CCs is provided more accurately and efficiently.
