APPARATUS AND A METHOD FOR TRANSMITTING/RECEIVING A TRANSFER RATE CONTROL BIT IN A MOBILE COMMUNICATION SYSTEM, PARTICULARLY FOR SAVING RESOURCES OF A BASE STATION BY TRANSMITTING A RATE CONTROL BIT AT A SPECIFIC SITUATION ONLY, NOT FOR EVERY FRAME

摘要

PURPOSE: An apparatus and a method for transmitting/receiving an RCB(Rate Control Bit) in a mobile communication system are provided to reduce power of a base station required for the transmission of an reverse-RCB to increase a forward throughput. CONSTITUTION: An RCB generator(201) generates an RCB for controlling a data rate in transmitting reverse packet data of a mobile terminal. A spreading unit(202) spreads the RCB to output it through a radio channel. A transmission power controller(203) outputs a control signal demanding that the RCB should not be transmitted, when information that the data rate cannot be increased any higher is received from the mobile terminal.
