PROBLEM TO BE SOLVED: To provide a communication system, base station device, mobile station device, and communication method that are capable of reducing interference between adjacent cells that is not coordinating.SOLUTION: A communication system is constituted by a base station device and a mobile station device. The base station device notifies the mobile station device of a downlink control information format including resource arrangement information for instructing to switch resource allocation of uplink demodulation reference signals to localized allocation or distributed allocation and a frequency offset of the distributed allocation of uplink demodulation reference signals unique to the mobile station device. According to information included in the downlink control information format, the mobile station device, when distributed allocation is instructed in the resource allocation information, determines resource allocation of the uplink demodulation reference signals on the basis of the frequency offset of the mobile station device; and transmits the uplink demodulation reference signals to the base station device.SELECTED DRAWING: Figure 6 |
