With the configurations up to the aspects above, a control information communication unit for communicating the control information about the communication by the first wireless base station device to the wireless terminal device and the control information about the communication by the second wireless base station device to the wireless terminal device between the first wireless base station device and the wireless terminal device can be further included. For example, the control information communication unit can perform the transmission of control information from the first wireless base station device to the wireless terminal device through a physical downlink control channel and perform the transmission of the control information from the wireless terminal device to the first wireless base station device through a physical uplink control channel. The physical uplink control channel in this case includes at least, for example, the individual channel quality indication information for each of the first wireless base station device and the second wireless base station device, and the precoding matrix indication information and the rank indication information common to the first wireless base station device and the second wireless base station device. In addition, the physical downlink control channel includes at least, for example, the individual modulation and coding scheme information and the individual precoding information for each of the first wireless base station device and the second wireless base station device.
