摘要： A reverse data transmission apparatus and method in a mobile communication system. A mobile station receives information about an MADR (Maximum Allowable Data Rate) from a base station in a first predetermined frame period, determines a data rate equal to or lower than the MADR, and requests the determined data rate to the base station. If an MADR received from the base station in a second frame period following the first frame period is higher than the requested data rate, the mobile station starts data transmission. Then, the mobile station measures a traffic to pilot ratio (T/P) from the base station and controls the data rate according to the T/P during data transmission.

摘要： A high rate packet data communication system and method are provided that can control a rate of a plurality of forward channels by transmitting/receiving data rate control (DRC) information over at least one DRC channel. In the system, at least one mobile station (MS) determines a transmission time of the DRC information such that a transmission period of the DRC information for each of the forward channels is equal, and sequentially transmits the DRC information repeatedly for the forward channels over at least one DRC channel for a predetermined number of slots. A base station (BS) determines a rate of a corresponding forward channel based on the DRC information received over at least one DRC channel.
