Document Type and Number:

WIPO Patent Application WO/2010/071039

Kind Code:

A1

Abstract:

A channel of an A-EUTRA component carrier which an EUTRA mobile station device does not wait for can be configured without substantially modifying the channel configuration of the conventional EUTRA. Provided is a radio transmission device which allocates one or more component carriers for the downlink so as to execute radio transmission to a plurality of radio reception devices. The radio transmission device includes a control channel element processing unit (17) which modifies for each of the component carriers, the structure of the downlink control channel used for transmitting control data destined to each of the radio reception devices. The control channel element processing unit (17) correlates the modulation symbol outputted from the downlink control channel processing unit (16) to a control channel element index and rearranges the resource element groups constituting the control channel element so as to be outputted to a multiplexing unit (19).
