Abstract: A power control method for reducing power consumption of a terminal during retransmission in a wireless communication system using spread spectrum may include: transmitting a response message corresponding to a request message received from a base station to the base station; determining whether an acknowledgement (ACK) message is received from the base station in response to the response message; after the ACK message is received, determining whether the response message is decoded by the base station on the basis of the ACK message; and when it is determined that the response message is not decoded by the base station, setting retransmission transmission power randomly.
