1. A radio communication apparatus comprising:

  • a transmitter, which, in operation, transmits control information associated with a number of bits; and

    a receiver, which, in operation, receives a bit sequence, in which each place of the number of bits determined from the control information out of a plurality of bits is forcibly set to a 1 and which is modulated by mapping the plurality of bits on a single modulation mapper, the plurality of bits forming a modulation symbol in the bit sequence, and the single modulation mapper having first signal points,wherein each place of the number of bits is forcibly set to the 1 in a way that the plurality of bits are mapped to one of second signal points, which are a part of the first signal points, a distance between the second signal points being equivalent to a largest of distance existing among the first signal points in an I-Q plane of the single modulation mapper.
