1. A base station comprising:
a transmitter which, in operation, transmits downlink data signals, and control information indicating starting positions, in a time domain, for a plurality of Acknowledgement/Negative Acknowledgement (ACK/NACK) repetition transmissions and starting positions, in the time domain, for a plurality of data signal repetition transmissions; and
a receiver which, in operation, receives the plurality of ACK/NACK repetition transmissions for the downlink data signals, and the plurality of data signal repetition transmissions, wherein,
the starting positions for the plurality of ACK/NACK repetition transmissions are the same as the starting positions for the plurality of data signal repetition transmissions,
each of the plurality of ACK/NACK repetition transmissions includes repetitions of an ACK/NACK signal mapped to consecutive subframes, and each of the plurality of data signal repetition transmissions includes repetitions of a data signal mapped to consecutive subframes,
a number of the repetitions of the data signal in each of the plurality of data signal repetition transmissions equals a number of the repetitions of the ACK/NACK signal in each of the plurality of ACK/NACK repetition transmissions,
in case a first ACK/NACK repetition transmission of the plurality of ACK/NACK repetition transmissions and a first data signal repetition transmission of the plurality of data signal repetition transmissions are both in first consecutive subframes, the first ACK/NACK repetition transmission and the first data signal repetition transmission are time-multiplexed in the first consecutive subframes in a Physical Uplink Shared Channel (PUSCH), and
in case a second ACK/NACK repetition transmission of the plurality of ACK/NACK repetition transmissions is in second consecutive subframes that do not include one of the plurality of data signal repetition transmissions, the second ACK/NACK repetition transmission is transmitted in the second consecutive subframes in a physical uplink control channel (PUCCH).
