## Abstract

A response signal in each subframe is multiplied by a corresponding one of components forming one of a plurality of first sequences orthogonal to each other. The response signal is also multiplied by a second sequence defined by one of a plurality of cyclic shift indexes and one of a plurality of third sequences orthogonal to each other. Among a plurality of resources, a resource associated with one of at least two first sequences of the plurality of first sequences is different from a resource associated with another one of the at least two first sequences. Each of the plurality of resources is constituted by one of the plurality of cyclic shift indexes and one of the plurality of third sequences.
