Abstract
The present invention relates to a transmission power control method which controls a transmission power of uplink user data for transmitting an uplink user data from a mobile station to a radio base station. The transmission power control method according to the present invention includes: transmitting, from the mobile station to the radio base station, a transmission data block which includes control information periodically, even when user data to be transmitted has not existed in a transmission buffer of the mobile station; notifying, at the radio base station, the number of retransmissions of the transmission data block, to a radio network controller; determining, at the radio network controller, a target SIR of a dedicated physical control channel in the radio base station based on the notified number of retransmissions and notifying the determined target SIR to the radio base station; controlling, at the radio base station, a transmission power of the dedicated physical control channel in the mobile station based on the notified target SIR; and determining, at the radio network controller, a transmission wave amplitude ratio between the uplink user data channel and the dedic…
