Abstract: The present invention, focusing on the fact that sometimes the channel (HS-SCCH) which notifies that data is to be transmitted will be received but it will be misdetected that there was a notification addressed to the receiving station, is to effectively utilize the channel (HS-SCCH) via which notification is conducted even in cases where the reception result is transmitted repeatedly. An HSDPA-compatible mobile station which, upon detecting that a message addressed to that mobile station was transmitted via HS-SCCH, receives the corresponding HS-PDSCH sub-frame, and which, when transmitting the reception result, repeats the transmission of said reception result n times, said mobile station being characterized in that it comprises a control unit which provides control such that reception processing is performed on the second sub-frame that comes next after the first sub-frame of HS-SCCH on which said detection was performed.
