摘要： A base station apparatus communicates with a mobile station apparatus transmitting a data signal and a reference signal for channel estimation. The base station includes: a simultaneous transmission setting part which sets simultaneous transmission control information indicating whether or not to enable simultaneous transmission of the data signal and the reference signal, a transmission section which transmits the set simultaneous transmission control information to the mobile station apparatus; and a radio resource control section which determines whether or not to enable simultaneous transmission of the data signal and the reference signal on the basis of a power headroom which is notified from the mobile station apparatus, the headroom being a difference between the maximum transmit power value of the mobile station apparatus and a prescribed power value estimated for uplink transmission.

摘要： It is possible to perform effective communication based on an A-SRS transmitted from a mobile station apparatus. A base station apparatus: notifies the mobile station apparatus of control information for setting, to the mobile station apparatus, whether to transmit a first sounding reference signal assigned in a physical uplink shared channel resource or to transmit a second sounding reference signal assigned in a resource different from the physical uplink shared channel resource; and notifies the mobile station apparatus of an uplink grant including an indication of transmission of a sounding reference signal. When receiving the indication of transmission of the sounding reference signal included in the uplink grant, the mobile station apparatus transmits the first sounding reference signal to the base station apparatus when the transmission of the first sounding reference signal is set by transmission control information, and transmits the second sounding reference signal to the base station apparatus when the transmission of the second sounding reference signal is set by the transmission control information.
