Abstract:
A method for transmitting a power control bit from a mobile station in a CDMA (Code Division Multiple Access) mobile communication system having a base station for extracting a power control bit received through a reverse pilot channel and controlling the transmitting power of a forward link, comprising the steps of:measuring a signal-to-interference ratio of a received signal; comparing the signal-to-noise ratio with a threshold value to generate a power control bit; and multiplexing the power control bit and pilot signals of a power control group of the reverse pilot channel and transmitting the multiplexed pilot signal and power control bit to a base station through the reverse pilot channel, wherein the multiplexing inserts the power control bit into a position within the power control group of the reverse pilot channel so that the pilot signals are located before and after the power control bit, and the pilot signals after the power control bit have a time period greater than a maximum round-trip propagation delay time between the base station and the mobile station.
