Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus and method for transmitting/receiving packet data in a mobile communications system. SOLUTION: A first transceiver transmits packet data and control information for enabling demodulation of the packet data to a second transceiver. The second transceiver receives the control information and the packet data, demodulates the packet data in accordance with the control information, and transmits ACK/NACK information indicating whether there is error in the packet data, and channel state information for the second transceiver, to the first transceiver. The second transceiver transmits the channel state information to the first transceiver in accordance with a predetermined channel state information transmission cycle, and transmits channel state information, regardless of the channel state information transmission cycle upon the receipt of an on-demand channel quality indicator from the first transceiver.
