Claim 0:
1. A base station comprising:
a transmitter, which, in operation, transmits, to a terminal, a downlink signal in a first short transmission time interval (sTTI) that is shorter than a subframe; and
a receiver, which, in operation, receives an uplink signal transmitted from the terminal in a second sTTI after a determined number of first sTTIs from a transmission timing of the downlink signal, the second sTTI being shorter than the subframe and longer than the first sTTI,
wherein the receiver, in operation, receives the uplink signal transmitted in the second sTTI that first occurs after the determined number of first sTTIs from the transmission timing of the downlink signal when a timing just after the determined number of first sTTIs from the transmission timing of the downlink signal does not match a boundary between second sTTIs.
