1. An integrated circuit comprising:
reception circuitry, which, in operation, controls receiving a control signal indicating a special subframe configuration including a length of an uplink portion of a special subframe including a downlink portion and the uplink portion, a second transmission time interval (TTI) for the uplink portion of the special subframe being shorter than a first TTI for an uplink subframe; and
transmission circuitry, which, in operation, controls transmitting user data based on the control signal,
wherein the special subframe configuration takes a value out of:
a first value indicating the length of the uplink portion, which is not sufficient to accommodate the user data in the second TTI, and
a second value indicating the length of the uplink portion, which is sufficient to accommodate the user data in the second TTI.
