<p>The present invention relates to a power controlling method in a mobile radio communication system using Automatic Repeat reQuest (ARQ) scheme, and more particularly to a power controlling method of response (ACK/NACK) signals for transmitting the ACK/NACK signals in different power based on the permissible probabilities of reception error that the system requires. When the ACK/NACK signals are transmitted and received in the automatic repeat request (ARQ) system, since the ACK/NACK signals can be transmitted in accordance with the transmission power satisfying an error rate required in each signal by differentiating the transmission power of the signal according to each ACK/NACK, the power consumption required in the transmission of the NACK signal can be reduced.</p> |
