Abstract:
1. A method for transmitting at a mobile station reverse channels in a Discontinuous Transmission (DTX) mode including a transmission interval and a non-transmission interval in a mobile communication system, comprising: if a reverse traffic channel is not transmitted, setting a power of a Reverse Rate indicator (RRI) channel to a first power level, transmitting the RRI channel on the first power level, transmitting a pilot channel in the transmission interval in the DTX mode, and not transmitting the pilot channel in the non-transmission interval in the DTX mode; and if the reverse traffic channel is transmitted, setting the power of the RRI channel to a second power level, transmitting the RRI channel on the second power level, and transmitting the pilot channel, wherein the RRI channel comprises information representative of data rate of the reverse traffic channel, and the first power level is equal to or higher than 0 and lower than the second power level.
