<P>PROBLEM TO BE SOLVED: To provide a transmission method of user data capable of transmitting user data at a high speed even if an active set is updated, and to provide a radio network control station. <P>SOLUTION: This user data transmission method has a process in which the radio network control station decides that a mobile station transmitting an enhanced dedicated physical control channel to only to a first cell transmits the enhanced dedicated physical control channel to the first cell and a second cell; a process in which the radio network control station notifies the mobile station about acknowledgement channel decoding information for decoding the acknowledgement channel of the uplink user data to be transmitted by the second cell to the mobile station; a process in which the mobile station transmits the enhanced dedicated physical data channel to the first cell and the second cell after receiving the decoding information; and a process in which the mobile station decodes the acknowledgement channel transmitted from the second cell and performs re-transmission processing of the uplink user data for the second cell based on the acknowledgement channel of the user data. <P>COPYRIGHT: (C)2007,JPO&INPIT |
