Patent ID: 8139534

Claim:
A mobile communication method in which a mobile station transmits an uplink packet at a transmission rate corresponding to a granted value notified by a radio base station, wherein a HARQ retransmission control is employed in a communication of the uplink packet transmitted from the mobile station to the radio base station; the granted value indicates a ratio between a transmission power in an enhanced dedicated physical data channel for transmitting the uplink packet, and a transmission power in an uplink dedicated physical control channel; and the mobile communication method comprises: controlling, at the radio base station, the transmission power in the uplink dedicated physical control channel by use of an inner loop transmission power control based on a target reception quality; transmitting, at the mobile station, the uplink packet, at the transmission power in the enhanced dedicated physical data channel, the transmission power being determined based on the granted value and the transmission power in the uplink dedicated physical control channel; and determining, at the radio base station, the target reception quality, by use of an outer loop transmission power control based on a HARQ transmission number and a reception result of an uplink packet transmission of the HARQ transmission number, the HARQ transmission number indicating what number transmission in the HARQ retransmission control is the uplink packet transmission.
