It is possible to effectively perform feedback in a communication system in which base station devices cooperatively communicate. A feedback information generation unit 208 has a function of adjusting the amount of information used for representing a channel estimated value which is output from a channel estimation unit 206, depending on each base station device. In other words, among a feedback information amount used for representing a channel estimated value between the mobile station device and the base station device connected to the mobile station device, and a feedback information amount used for representing a channel estimated value between the mobile station device and a base station device other than the base station device connected to the mobile station device, the feedback information amount used for representing one type of channel estimated value is adjusted so as to be less than the feedback information amount used for representing the other type of channel estimated value. |
