The present invention discloses a method for retransmitting hybrid automatic based on persistent scheduling. The method includes: a base station sending retransmission attribute information of a persistent scheduling service to a terminal by a control signaling. An HARQ mechanism under a persistent scheduling mode is perfected by defining a retransmission region of the persistent scheduling service, and retransmission data packets are centralized to be transmitted in the retransmission region at a synchronization time, which, compared with the prior art, saves the overhead of resource indication information indicating each retransmission packet.
