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.

1. A method for controlling an uplink transmit power by a user equipment in a wireless communication system, comprising:
determining uplink transmit power value for each of a plurality of allocated transmission channels; sequentially allocating the uplink transmit power values to the transmission channels starting from a transmission channel corresponding to the highest priority according to predefined priorities of the plurality of transmission channels if the total sum of each of the determined uplink transmit power values for the plurality of transmission channels is greater than a maximum transmit power value of the user equipment; and simultaneously transmitting the plurality of transmission channels with the allocated uplink transmit power values, wherein the transmission channel having the highest priority is a Hybrid Automatic Repeat reQuest (HARQ) feedback channel for responding to whether at least one of a downlink persistent allocation A-MAP IE message, a feedback allocation A-MAP IE message, an uplink persistent allocation A-MAP IE message, and a feedback polling A-MAP IE message has been successfully received.
