| 发明名称 | Method and apparatus for controlling transmit power of user equipment | ||
| 摘要 | The present invention provides a method and an apparatus for controlling transmit power of a user equipment, the method includes reducing a gain factor of a first-type channel of the UE when total uplink transmit power of the UE exceeds maximum allowed transmit power. The method further includes determining total uplink transmit power of the UE and if the total uplink transmit power of the UE exceeds the maximum allowed transmit power and the gain factor of the first-type channel is reduced to a preset gain factor threshold, reducing a gain factor of a second-type channel of the UE so that total uplink transmit power of the UE does not exceed the maximum allowed transmit power. | ||

| 主权项 | 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. | ||
