Abstract: A mobile station (MS) receives a first reception signal using a first downlink component carrier (DCC) and receives a second reception signal using the second DCC. The first reception signal includes a synchronization signal, a first physical channel, and a first reference signal.

The MS extracts the information from the first reception signal carried after the mobile station establishes connection in a first cell via a cell search using the synchronization signal. The second DCC is used simultaneously with the first DCC.
