Abstract
A mobile communication method according to the present invention includes: controlling, at the radio base station NodeB, the transmission power in the DPCCH by use of an inner loop transmission power control based on a target SIR; transmitting, at the mobile station UE, the uplink packet, at the transmission power in the E-DPDCH, the transmission power being determined based on the SG and the transmission power in the DPCCH; and determining, at the radio base station NodeB, the target SIR, 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.
