Patent ID: 8489105

Claim:
A radio base station comprising: a transceiver configured to transmit data to a radio communication device and receive data from the radio communication device using a plurality of component carriers simultaneously using spectrum aggregation, each component carrier comprising a pre-defined frequency band comprising a plurality of resource elements; a component carrier determiner configured to: determine a subset comprising at least one component carrier of the plurality of component carriers, wherein the at least one component carrier of the subset is used by the radio communication device for a pre-defined communication mode; and identify an anchor carrier of the at least one component carrier of the subset to be used for the pre-defined communication mode; and a message generator configured to generate a message comprising information specifying that the at least one component carrier of the subset is used by the radio communication device for the pre-defined communication mode and specifying the anchor carrier of the at least one component carrier of the subset to be used for the pre-defined communication mode, and wherein the message further comprises information specifying a bandwidth range for dynamic scheduling used to indicate the bandwidth range in at least one of uplink and downlink to be used by the radio base station for dynamic scheduling based on the anchor carrier.
