Abstract  Abstract

The invention relates to a composition carrier activation/deactivation applying carrier aggregation communication system wherein the component carrier activation/deactivation information to activate or disable in uplink or downlink is one or a plurality of component carriers. Furthermore the present invention relates to is used for activation/deactivation setting for the mobile terminal of the downlink component carriers in the method using the new composition carrier activation/deactivation information and the base station and the mobile terminal. In order to be able to efficient and stable of activation/deactivation component carriers the invention suggests using component carriers or cell-specific scrambling E-RNTI of the component carrier activation/CRC is disabled and dominant indicating the component carrier activation in the corresponding field of the message/intended recipient is disabled. In addition the invention also claims composition carrier activation/a design and other use of them as disabling information CQI report so as to trigger the mobile terminal and/or SRS transmission.

This invention relates to the proposal of component carrier (de)activation message that is allowing a activation or deactivation of one or more component carriers in the uplink or downlink. Furthermore the invention relates to the use of the new component carrier (de)activation message in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers the invention proposes to use component carrier-specific or cell-RNTI(s) for the scrambling of the CRC of the component carrier (de)activation message and to explicitly indicate the intended recipient of the component carrier (de)activation message in a corresponding field in the message. Furthermore the invention further proposes different designs of the component carrier (de)activation message and further uses thereof so as to trigger CQI reporting and/or SRS transmission by a mobile terminal.
