1. A method for managing aggregation of component carriers between an e Node B and a user equipment, wherein, a primary component carrier being a component carrier usable before carrier aggregation is configured, and a secondary component carrier being a component carrier usable only when carrier aggregation is configured, the method comprises:
- /a/ reporting, by the user equipment, component carriers aggregation capabilities of the user equipment to the e Node B through a primary component carrier;
/b/ transmitting a measurement report from the user equipment to the e Node B, wherein the measurement report contains a list of reliable secondary component carriers;
/c/ configuring, in the user equipment, by the e Node B, a first set consisting of secondary component carriers which, based on the reports received in steps /a/ and /b/, are reliable and which the user equipment is able to manage;
/d/ activating, by the e Node B, at least one secondary component carrier from the first set, and providing, by the e Node B, a second set consisting of the primary component carriers and of all activated secondary component carriers;
wherein the component carriers of the second set are the only ones that can be used to communicate data between the e Node B and the user equipment, and wherein a secondary component carrier can be activated only if it belongs to the first set.

14. An e Node B arranged to manage the aggregation of component carriers with a user equipment, wherein, a primary component carrier being a component carrier usable before carrier aggregation is configured, and a secondary component carrier being a component carrier usable only when carrier aggregation is configured, the e Node B comprises:
-
a receiver for obtaining, from the user equipment, through a primary component carrier, a component carriers aggregation capabilities report and a measurement report, wherein the measurement report contains a list of reliable secondary component carriers; a processor configured for providing a first set consisting of secondary component carriers which, based on the reports received by the receiver, the user equipment is able to manage, for activating at least one secondary component carrier from the first set, and for providing a second set consisting of the primary component carriers and of all activated secondary component carriers; wherein the component carriers of the second set are the only ones that can be used to communicate data between the e Node B and the user equipment, and wherein only a component carrier of the first set can be activated.

15. A user equipment arranged to manage the aggregation of component carriers with an e Node B, wherein, a primary component carrier being a component carrier usable before carrier aggregation is configured, and a secondary component carrier being a component carrier usable only when carrier aggregation is configured, the user equipment comprises:
-
a transmitter for sending, to the e Node B, through a primary component carrier, a component carriers aggregation capabilities report and a measurement report, wherein the measurement report contains a list of reliable secondary component carriers; a receiver for receiving a first set consisting of secondary component carriers which, based on the reports sent by the transmitter, the user equipment is able to manage; a processor for activating at least one secondary component carrier from the first set, and for providing a second set consisting of the primary component carriers and of all activated secondary component carriers; wherein the component carriers of the second set are the only ones that can be used to communicate data between the e Node B and the user equipment, and wherein only a component carrier of the first set can be activated.
