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.

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).
