When a determination section of a reception apparatus determines that a
control channel is intended for the reception apparatus, a comparing
section of the reception apparatus compares control information
transmitted on the control channel with a reception capability of the
reception apparatus. A data channel reception section of the reception
apparatus receives a data channel when the control information is within
the reception capability of the reception apparatus, but does not receive
the data channel when the control information exceeds the reception
capability of the reception apparatus. When the control information
exceeds the reception capability of the reception apparatus, the
transmission section does not transmit an ACK signal and a NACK signal
with respect to the data channel.
