Claim Text:
1. A method for controlling transmit power of a user equipment (UE), wherein the method comprises: reducing a gain factor of an enhanced dedicated physical data channel (E-DPDCH) when a first total uplink transmit power of the UE exceeds a maximum allowed transmit power; determining a second total uplink transmit power of the UE after reducing the gain factor of the E-DPDCH; reducing gain factors of an enhanced dedicated physical control channel (E-DPCCH) and a high speed dedicated physical control channel (HS-DPCCH) when the second total uplink transmit power of the UE exceeds the maximum allowed transmit power and a transmit power of the E-DPDCH is reduced to 0; determining a fourth total uplink transmit power of the UE after reducing the gain factors of the E-DPCCH and HS-DPCCH; and reducing a gain factor of a second-type channel of the UE when the fourth total uplink transmit power of the UE exceeds the maximum allowed transmit power and the gain factors of the E-DPCCH and HS-DPCCH are reduced to a respective preset gain factor threshold, so that a fifth total uplink transmit power of the UE, after reducing the gain factor of the second-type channel, does not exceed the maximum allowed transmit power, wherein the second-type channel comprises a dedicated physical channel.
