Abstract  Abstract

The invention claims a component carrier activation/disabling the suggestion message the component carrier activation/deactivation of one or multiple component carrier message allowing activation or deactivation in the up-link or down-link. In addition the invention relates to the activation/deactivation of downlink component carrier is set by the mobile terminal in the method of using the new component carrier activation/deactivation information and base station and mobile terminal. In order to be able to efficiently and steadily activated/deactivated component carrier the invention proposes using component carrier-specific or cell specific RNTI for scrambling the component carrier activation/deactivation CRC of the message and indicating the component carrier activation in the corresponding field of the message/disable the intended recipient of the message. In addition the invention also claims the component carrier activation/deactivation different designs of other message and they use to trigger the CQI reporting and/or SRS sent by the mobile terminal.

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.
