Claim:
1. A terminal device configured to communicate with a base station device, the terminal device comprising: reception circuitry configured to transmission circuitry configured to, in a case that the information requesting the transmission of the sounding reference signal is received in a subframe n, transmit the sounding reference signal in a first subframe configured by a higher layer and satisfying n+k (k≧4), wherein the transmission circuitry is configured not to transmit the sounding reference signal in a case that the first subframe configured by the higher layer and satisfying n+k (k≧4) is a downlink subframe based on the uplink-downlink configuration indicated by the third information, transmission on a physical uplink shared channel corresponding to the physical downlink control channel is based on the uplink-downlink configuration indicated by the first information, and transmission of an HARQ-ACK in response to detection of the transmission on the physical downlink shared channel corresponding to the physical downlink control channel is based on the uplink-downlink configuration indicated by the second information.
