Activate / deactivate component carrier system using carrier aggregation method and a communication system provided in
2011
The present invention relates to a component carrier activation / deactivation proposal message, the component carrier activation / deactivation message allows to activate or deactivate an uplink or downlink or more component carriers. Further, the present invention relates to a new method for the component carrier activation / deactivation of the set of downlink component carriers to a mobile terminal in the activation / deactivation message, and the base station and the mobile terminal. In order to be efficient and robust activation / deactivation component carriers, the present invention proposes the use of a specific component carrier cell-specific RNTI or a component carrier activation / deactivation message CRC is scrambled, and explicitly indicated components in the respective fields of the message carrier activate / deactivate the intended recipient of the message. Further, the present invention is further recommended that component carrier activation / deactivation of different design and their use other messages, to trigger the CQI report of the mobile terminal and / or SRS transmission.
