1. An integrated circuit comprising:
transmission circuitry, which, in operation, controls transmitting, to a terminal, control information indicating whether transmission of a sounding reference signal (SRS) is requested and indicating a transmission parameter of the SRS, wherein the transmission circuitry, in operation, controls performing no two or more transmissions of the control information indicating different transmission parameters within a determined period; and
reception circuitry, which, in operation, controls receiving the SRS, which is transmitted from the terminal based on the control information.
