Claim:
1. A method for controlling transmit power of a terminal, wherein the method comprises: reducing a gain factor of an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) of the terminal when a first total uplink transmit power of the terminal exceeds a maximum allowed transmit power; reducing, if a transmit power of the E-DPDCH is reduced to 0, a gain factor of an enhanced dedicated physical control channel (E-DPCCH); determining a second total uplink transmit power of the terminal after reducing the gain factor of the DPCCH; reducing, if the second total uplink transmit power of the terminal exceeds the maximum allowed transmit power and the gain factor of the E-DPCCH is reduced to a second preset gain factor threshold, a gain factor of a high speed dedicated physical control channel (HS-DPCCH); determining a third total uplink transmit power of the terminal after reducing the gain factor of the HS-DPCCH; and reducing, if the third total uplink transmit power of the terminal exceeds the maximum allowed transmit power and the gain factor of the HS-DPCCH is reduced to a first preset gain factor threshold, a gain factor of a dedicated physical control channel (DPCCH) and a gain factor of a dedicated physical data channel (DPDCH).
