Method and apparatus for handling errors in a synchronous ul harq process

PURPOSE: A method and a device for handling errors in a synchronous uplink HARQ(Hybrid Automatic Retransmission reQuest) process are provided to prevent interference in a base station, thereby increasing uplink performance in the entire cells. CONSTITUTION: A terminal obtains synchronous uplink HARQ resource information through a transmitted uplink A-MAP(301). The terminal transmits an initial uplink HARQ burst in one time slot based on the information(303). The base station transmits the uplink A-MAP including information related to resources for changing a synchronous uplink HARQ(305). The base station finally transmits NACK(Negative ACKnowledge) again(307).
