Abstract

There are provided a terminal device, a base station device, and an integrated circuit that enable a base station device and a terminal device to determine parameters related to uplink signals or uplink reference signals and to perform efficient communication. A terminal device that transmits a demodulation reference signal associated with a physical uplink shared channel includes determining a value related to a cyclic shift on the basis of a value of a parameter configured by a higher layer, determining the value related to the cyclic shift on the basis of a physical layer cell identity, and generating a sequence of the demodulation reference signal on the basis of the value related to the cyclic shift, wherein the value related to the cyclic shift is determined on the basis of the physical layer cell identity in a case where a transmission on the physical uplink shared channel corresponding to a downlink control information format to which CRC parity bits scrambled by a Temporary C-RNTI are attached is performed.
