Method and base station for locating HARQ feedback to the corresponding hop

According to the present invention, it proposes a base station and a user terminal between a multi-hop data transmission system comprising at least one relay node of the base station received by the hybrid automatic repeat request HARQ feedback positioning methods corresponding to the jumping, comprising: the base station receives the HARQ feedback for the data transmission of the k-hop, HARQ feedback is a negative acknowledgment ACK or NACK feedback signaling acknowledgment, where k is an integer of 1; Analyzing the HARQ feedback indicates the k-hop data transmission ACK or NACK, and is positioned under a HARQ feedback in the time domain according to the determination result of the HARQ feedback (k + 1) data transmission hops or hop for the k-th data retransmission HARQ feedback.
