TERMINAL FOR CONTROLLING UPLINK TRANSMISSION POWER AND AN UPLINK TRANSMISSION POWER CONTROL METHOD IN A WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed are a terminal for controlling uplink transmission power and an uplink transmission power control method in a wireless communication system. In the terminal according to the present invention, if the total sum of uplink transmission power values respectively determined for a plurality of transmission channels is greater than the maximum transmission power value of the terminal, a processor can allocate respective uplink transmission power values sequentially in accordance with priority rankings across the plurality of transmission channels which have been determined in advance, starting from the transmission channel corresponding to the highest priority ranking. An emitter can simultaneously transmit the plurality of transmission channels with each of the allocated uplink transmission power values, and the transmission channel having the highest priority ranking can be a HARQ (Hybrid Automatic Repeat Request) feedback channel for responding as to whether there has been successful receipt of at least one message selected from a downlink persistent allocation A-MAP IE (DL persistent allocation A-MAP IE) message, a feedback allocation A-MAP IE message, an uplink persistent allocation A-MAP IE (UL persistent allocation A-MAP IE) message and a feedback polling A-MAP IE message.
