Abstract
Disclosed is an apparatus and method for transmitting and receiving control information for a packet data channel in a mobile communication system supporting a high-speed packet data service and a circuit voice service. A base station generates control information indicating an encoder packet size, a code rate and the number of Walsh codes used for transmission of packet data to a mobile station, and transmits the generated control information over a packet data control channel. The mobile station receives the control information over the packet data control channel while receiving the packet data over the packet data channel, and decodes the received packet data according to a modulation order determined based on the received control information.
