Abstract

A transmission power control method in a wireless communication system comprises the steps of receiving from a base station via an overhead message a first gain value (S23) associated with controlling transmission power for transmitting data acknowledge information (ACK, NAK) and a second gain value (S13) associated with controlling transmission power for transmitting channel quality information (CQI) wherein the transmission power of the reverse-acknowledgment channel (R-ACKCH) and the reverse-channel quality indicator channel (R-CQICH) are independently determined (S24, S14) using said first and second gain values.
