1. A base station comprising:
circuitry, which, in operation, allocates a frequency region including a plurality of frequency resources to a terminal; and
a receiver, which, in operation, receives a signal, which is generated based on both a plurality of cyclic shift indexes that are associated with the plurality of frequency resources, respectively, and another cyclic shift index that is configured per terminal, and which is transmitted from the terminal.
