A mobile communications system includes a base station that performs packet data communications with a terminal. The base station includes a communication unit that receives a data rate control (DRC) value and a message from the terminal, the message including pilot channel information detected from a pilot channel signal sent to the terminal from the base station; a packet data generating unit that generates packet data according to the DRC value; and a control unit determines a number of active sets based on the pilot channel information, and dynamically controls a DRC length based on the determined number of active sets. Also, the control unit controls the communication unit to transmit the dynamically controlled DRC length information to the terminal. Accordingly, the DRC length is dynamically controlled to be more compatible with a wireless environment.
