Abstract:
A method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting an uplink packet data service are provided. To transmit packet data in an HARQ mobile communication system, a second transceiver receives an RG as rate control information from a first transceiver. The second transceiver sets the allowed maximum data rate of an HARQ process to which the RG is applied to the allowed maximum data rate of an HARQ process previous to the HARQ process, if the RG indicates hold. The second transceiver transmits packet data within the set allowed maximum data rate to the first transceiver.
