Abstract

Repetitions of a control signal across a plurality of first subframes and a data signal allocated to a resource indicated by the control signal are received. Repetition of a response signal for the data signal across a plurality of second subframes is performed, and a transmission signal is generated by multiplying the response signals in the second subframes by, among a plurality of first sequences orthogonal to one another, components of one of the first sequences which is associated with the first subframes, respectively.

Claims

1. A terminal, comprising:

a receiver, which, in operation, receives repetitions of a control signal across a plurality of first subframes and a data signal allocated to a resource indicated by the control signal;

a generator, which, in operation, performs repetition of a response signal for the data signal across a plurality of second subframes and generates a transmission signal by multiplying the response signals in the plurality of second subframes by respective resource blocks which are associated with one of the plurality of first subframes; and

a transmitter, which, in operation, transmits the transmission signal.

2. The terminal according to claim 1, wherein a number of repetitions of the repetition of the response signal is an integer multiple of a subframe period in which repetition transmission is started.
