Transmit power control method and apparatus

摘要

A method and apparatus for controlling transmit power of a User Equipment (UE) in a mobile communication system is provided. The transmit power control method of the present invention includes determining, when the terminal's required transmit power exceeds the terminal's maximum transmit power, whether a plurality of Hybrid Automatic Repeat reQuest (HARQ) processes are running and reducing, when the plurality of HARQ processes are running, a transmit power of at least one of the plurality of HARQ processes which has not experienced transmit power reduction previously. The UE transmit power control method and apparatus of the present invention is advantageous to control the transmit power in transmit power reduction mode.

1. A transmit power control method of a terminal, the method comprising:
determining, if a required transmit power of the terminal exceeds a maximum transmit power of the terminal, whether a plurality of Hybrid Automatic Repeat reQuest (HARQ) processes are running, wherein each of the plurality of HARQ processes is an independent HARQ process managing HARQ packets; selecting, if the plurality of HARQ processes are running, at least one of the plurality of HARQ processes which has not experienced transmit power reduction previously and reducing a transmit power of the selected at least one HARQ process; and reducing, if each of the plurality of HARQ processes has previously experienced a transmit power reduction the transmit power of one of the plurality of HARQ processes that has experienced the fewest number of previous power reductions.
