FIELD: physics, communications.
SUBSTANCE: transmission power control method is claimed. The technical effect is that E-DCH HARQ acknowledgement indicator channels (E-HICH) may reach a mobile station even when it is in the process of soft handover. For that purpose, the method of transmission power control for E-HICH transmission power control for uplink user data, transmitted from the cell, controlled by the radio communication base station, to the mobile station includes stages, at which: the radio network controller is used to specify at least one radio communication base station controlling the first cell and the second cell, the offset between the E-HICH transmission power and the dedicated physical channel (DPCH) transmission power, when the mobile station is in the process of soft handover with the first and second cells; at the first cell, the transmission power of the first E-HICH is determined based on the specified offset and the first E-HICH is transmitted to the mobile station using a certain transmission power; at the second cell, the transmission power of the second E-HICH is determined based on the specified offset and the second E-HICH is transmitted to the mobile station using a certain transmission power.
EFFECT: possibility of reaching mobile station signal in any communication mode including soft handover mode.
