摘要：
For efficient transmission of a first reference signal and a second reference signal for channel estimation without deteriorating a channel estimation accuracy, and without deteriorating a communication quality, a mobile station apparatus, in the case where a transmission of the first reference signal and a transmission of the second reference signal coincide in the same timing (Step S101, YES), performs transmission of the first reference signal (Step S102), and in contrast, in the case where a transmission of the first reference signal and a transmission of the second reference signal have happened to coincide in different component carriers in the same timing (Step S101, NO), performs a transmission of the first reference signal and a transmission of the second reference signal simultaneously (Step S103).
