1. An integrated circuit comprising:
circuitry, which, in operation, controls:
receiving a signal including ACK/NACK information indicating error correction results;
determining an amount of resource of control information in a plurality of layers; and
extracting the ACK/NACK information from the received signal based on the amount of the resource per layer, wherein
the amount of the resource QCW#0+CW#1 of the control information is determined by equation 1:, (
