| 摘要 | A base station which uses either one of a plurality of component carriers individually or uses an aggregate carrier which is an aggregate of the above-mentioned plurality of component carriers to carry out radio communications with a mobile terminal corresponding to the above-mentioned component carrier and also carry out radio communications with a mobile terminal corresponding to the above-mentioned aggregate carrier is provided. The base station notifies a bandwidth of an aggregate carrier which is an aggregate of all of the above-mentioned component carriers, as a bandwidth which the above-mentioned base station uses, to the mobile terminal corresponding to the above-mentioned aggregate carrier. As a result, while an improvement in the transmission rate is provided according to the aggregate carrier, the base station can also support an operation of a mobile terminal corresponding to a component carrier. | ||

| 主权项 | 1. A base station which uses either one of a plurality of component carriers individually or uses an aggregate carrier which is an aggregate of said plurality of component carriers to carry out radio communications with a mobile terminal supporting said component carrier and also carry out radio communications with a mobile terminal supporting said aggregate carrier, where the mobile terminal supporting the component carrier does not support said aggregate carrier wherein said base station broadcasts information indicating a frequency band of a multi carrier anchor included in said aggregate carrier such that the mobile terminal supporting said aggregate carrier can be configured to receive the multi carrier anchor, andnotifies, by using the frequency band indicated by the broadcasted information, a bandwidth of an aggregate carrier which is an aggregate of said plurality of component carriers, as a bandwidth which said base station uses, to the mobile terminal supporting said aggregate carrier, the bandwidth of the aggregate carrier being indicated in system information of said aggregate carrier. | ||
