1. A transmission device comprising:
circuitry, which, in operation:
generates a reference signal by using a sequence having a sequence length according to a ratio of one subcarrier spacing among a plurality of subcarrier spacings to the maximum subcarrier spacing among the plurality of subcarrier spacings; and
maps the reference signal to subcarriers at determined intervals; and
a transmitter, which, in operation, transmits the reference signal,
wherein the determined intervals have a length that is a reciprocal of the ratio.
