A user data transmission method for transmitting uplink user data via an E-DPDCH, including: determining, at a radio network controller, that the mobile station transmitting the E-DPDCH to only a first cell transmits the E-DPDCH to the first cell and a second cell; notifying, at the radio network controller, E-RGCH decoding information for decoding a E-RGCH for the uplink user data to be transmitted by the second cell, to the mobile station based on the determination; transmitting, at the mobile station, the E-DPDCH to the first cell and the second cell, after the E-RGCH decoding information is received; and decoding, at the mobile station, the E-RGCH from the second cell based on the relative transmission rate control channel decoding information, and controlling the transmission rate of the uplink user data based on a relative transmission rate for the uplink user data which is notified by the decoded E-RGCH.
