RADIO COMMUNICATION MOBILE STATION APPARATUS AND RADIO COMMUNICATION METHOD

摘要

Determination section 107 determines whether a control channel is intended for a reception apparatus having the determination section 107, and when it is determined that the control channel is intended for the reception apparatus, capability comparing section 113 compares control information transmitted on the control channel with the reception capability of the reception apparatus. Data channel reception section 108 receives a data channel when the control information is within a scope of the reception capability of the reception apparatus, while not receiving the data channel when the control information is out of a scope of the reception capability of the reception apparatus. Further, when the control information is out of the scope of the reception capability of the reception apparatus, transmission section 112 does not transmit an ACK signal and NACK signal in response to the data channel.
