Abstract: PURPOSE: A method of controlling voltage of a CDMA communication system and a device thereof are provided to enable a moving station to control the up-link transmission power and operate up-link transmission rate variably corresponding to the channel conditions. CONSTITUTION: In a device of controlling the power of a CDMA communication system, a detector(410) catches channel signal. fingers for Data demodulation(421-42N) demodulate received signals and produces data. A data combiner(440) combines the signal data from the fingers for Data demodulation(421-42N). A decoder(442) decode the combined data. Fingers(431-43M) measuring signal level and interference measure the signal level and interference respectively. A combiner(450) for S/N rate combines all the signal levels and the amounts of interference. A controller(460) processes the signals from the decoder(442) and the combiner(450) for S/N rate. The controller(460) produces a signal-interference rate to control the transmission power of the up-link channel of the base station using the signal level and the amount of interference. A transmitter(470) transmits the signal-interference rate of up-link processed at the controller(460).

Abstract: PURPOSE: A device and method for performing access communication in a mobile communication system is provided to detect a starting point that a mobile station transmits a responding message for a control message without transmitting specific time information from a base station to the mobile station, so as to communicate data through a common channel in a communication system servicing multimedia data communication. CONSTITUTION: A system receives an access parameter message including information on a slot length and a preamble length through a forward common channel. The system checks dedicated information for designating a reverse common channel included in a control message received from the forward common channel as a dedicated channel. The system transmits a preamble during a section corresponding to the preamble length from a slot length limit. After transmitting the preamble, the system spreads a responding message for a control message as a spread code by the dedicated information, and transmits the spread responding message. After transmitting the spread responding message, the system checks whether a preamble non-acquisition display is received from a base station. The system returns to a preamble transmission step at the next detected slot limit.
