Abstract

An HARQ(Hybrid Automatic Retransmission Request) method and a device in a mobile communication system are provided to improve the performance of ARQ operations by judging the error state of NACK/ACK(Negative Acknowledgement/Acknowledgement) through an HARQ block and then transmitting a local feedback signal for each ARQ block. An HARQ method in a mobile communication system includes the steps for receiving a feedback signal for an HARQ data packet transmitted from an HARQ transmission block; checking an error according to the reception result of the received feedback signal; and reporting a local feedback signal(517) to the corresponding ARQ block according to the error state of the feedback signal, wherein the corresponding ARQ block is operated by the local feedback signal.
