Claim of US Patent No. 10,117,236

1. A terminal comprising:a first spreader that performs primary spreading on a response signal by using one of a plurality of second sequences defined by different cyclic shift indexes;
a second spreader that performs secondary spreading on the response signal having been subjected to the primary spreading by using one of a plurality of third sequences orthogonal to each other in a subframe;
a generator that generates a transmission signal repetitively over multiple subframes by multiplying, in each subframe, the secondarily-spread response signal by one of components of one sequence of a plurality of first sequences orthogonal to each other; and
a transmitter that transmits the transmission signal repetitively over the multiple subframes.
