WIRELESS COMMUNICATION SYSTEM, BASE STATION APPARATUS, COMMUNICATION APPARATUS, AND COMMUNICATION CONTROL PROGRAM

摘要

A CA decision part selects a component carrier to be used for communication with a terminal apparatus from component carriers used for communication by a plurality of base station apparatuses. A CA set notification part notifies a sub-base station apparatus of carrier aggregation information indicating the component carrier selected by the CA decision part. A transmission unit of a main base station apparatus allocates a signal, which is obtained by modulating a part of data to be transmitted to the terminal apparatus, on a first component carrier selected by the CA decision part, and transmits the signal. A transmission unit of the sub-base station apparatus allocates a signal, which is obtained by modulating a part of the data to be transmitted to the terminal apparatus, on a second component carrier indicated by notified carrier aggregation information, and transmits the signal. A reception unit of the terminal apparatus receives the signal from the main base station apparatus using the first component carrier and the signal from the sub-base station apparatus using the second component carrier. A wireless processing part integrates the signals received by the reception unit.
