An apparatus and method for transmitting / receiving packet data in a mobile communication system. 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 according to the control information, and transmits ACK / NACK information indicating whether there is an error in the packet data, and channel state information for the second transceiver, to the first transceiver. The second transceiver transmits channel state information to the first transceiver according to a predetermined channel state information transmission cycle, and transmits channel state information regardless of the channel state information transmission cycle upon receiving an on-demand channel quality indicator (ODC) from the first transceiver.
Description
technical field [0001] The present invention generally relates to an apparatus and method for transmitting control information for retransmitting high-speed packet data in a Wideband Code Division Multiple Access (WCDMA) mobile communication system. In particular, the present invention relates to an apparatus and method for retransmitting high-speed packet data using a control channel to transmit / receive an on-demand Channel Quality Indicator (CQI), also referred to as On-demand CQI or ODC. Background technique [0002] Mobile communication systems are evolving into high-speed, high-quality wireless data packet communication systems for providing data services and multimedia services superior to earlier voice services. For third-generation (3G) mobile communication systems that are divided into asynchronous third-generation partnership project (3GPP) systems and synchronous third-generation partnership project 2 (3GPP2) systems, high-speed, high-quality wireless data packet...
