TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

According to the present invention, there is provided a base station device, a terminal device, a communication method, an integrated circuit, and a radio communication system enabling a base station and a mobile station device to decide a parameter related to a reference signal and efficiently communicate. A terminal device receives a reference signal associated with a physical downlink shared channel, the terminal device including means that receives the reference signal generated on the basis of a physical layer cell identity in a case in which a predetermined downlink control information format is used for scheduling of the physical downlink shared channel, and means that receives the reference signal generated on the basis of a parameter configured by a higher layer in a case in which a downlink control information format other than the predetermined downlink control information format is used for scheduling of the physical downlink shared channel.
