FIELD: physics, communications.
SUBSTANCE: there is proposed a method of controlling transmission power in an enhanced relative grant channel (E-RGCH) for uplink user data transmitted from a cell controlled by a radio communication base station to a mobile station. The method involves the following steps on which: a 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-RGCH 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; in the first cell, the transmission power of the first E-RGCH is determined based on the specified offset and the first E-RGCH is transmitted to the mobile station using a certain transmission power; in the second cell, the transmission power of the second E-RGCH is determined based on the specified offset and the second E-RGCH is transmitted to the mobile station using a certain transmission power.
EFFECT: enabling a mobile station to control rate of transmission of uplink user data based on "down" commands from the cell.
