1. A radio base station, comprising:
- a transceiver configured to communicate with a radio communication device using a plurality of component carriers; and
a message generator configured to generate an idle mode message including an information item related to at least one of the component carriers of the plurality of component carriers of the radio base station;
wherein the transceiver is further configured to transmit the generated idle mode message to the radio communication device;
wherein the transceiver is further configured to transmit the generated idle mode message to the radio communication device using a pre-defined component carrier;
wherein the information item comprises cell selection/reselection prioritization information indicating which one of cell selection/reselection and component carrier selection has higher priority for the radio communication device when leaving the pre-defined component carrier;
wherein the information item comprises allowed component carrier information indicating at least one component carrier as a candidate for component carrier selection for the radio communication device; and
wherein at least one component carrier as a candidate for component carrier selection for the radio communication device is represented by at least one of a frequency band in which the at least one component carrier is located and a frequency distance between the center frequency of the at least one component carrier and the pre-defined component carrier.

6. A radio communication device, comprising:
-
a transceiver configured to communicate with a radio base station using a plurality of component carriers; wherein the transceiver is further configured to receive an idle mode message from the radio base station; and a message extractor configured to extract from the received idle mode message an information item related to at least one of the component carriers of the plurality of component carriers of the radio base station, wherein the transceiver is further configured to receive the idle mode message from the radio base station using a pre-defined component carrier, wherein the information item comprises cell selection/reselection prioritization information indicating which one of cell selection/reselection and component carrier selection has higher priority for the radio communication device when leaving the pre-defined component carrier; wherein the information item comprises allowed component carrier information indicating at least one component carrier as a candidate for component carrier selection for the radio communication device; wherein at least one component carrier as a candidate for component carrier selection for the radio communication device is represented by at least one of a frequency band in which the at least one component carrier is located and a frequency distance between the center frequency of the at least one component carrier and the pre-defined component carrier. - View Dependent Claims (7, 8, 9, 10, 11, 12)
