BASE STATION APPARATUS, PROGRAM, INTEGRATED CIRCUIT, MOBILE STATION APPARATUS, AND COMMUNICATION SYSTEM

摘要

The objective of the invention is to reduce frequency resources that are required for a cooperative communication in an upstream line. A base station apparatus, which is applied to a communication system in which a plurality of base station apparatuses communicate with at least one mobile station apparatus in a cooperative communication, comprises: an inter-base-station communication unit (220) that communicates with another base station apparatus during performance of a cooperative communication; and a control information determining unit (216) that performs allocation of a band, which is to be used by the mobile station apparatus for communication, such that the signals received at the other base station apparatus in a cooperative manner overlap in frequency with the signals received at the other base station apparatus in a non-cooperative manner.
