Disclosed are a retransmission processing method and device for a multi-user system. The method comprises: pairing users in a retransmission user group with users in a new transmission user group in accordance with a preset rule; and according to a pairing result, determining whether to conduct space division multiplexing on the users in the retransmission user group and the new transmission user group, wherein if the pairing result indicates that the pairing is successful, conducting space division multiplexing on the users who are paired successfully in the retransmission user group and the new transmission user group, and if the pairing result indicates that the pairing fails, prohibiting the conducting of space division multiplexing on any user in the retransmission user group and the new transmission user group. The present invention solves the problem in the related art that the reduction of the accuracy of retransmission users, caused by blindly conducting multiplexing on the retransmission users and other users, has a relatively great negative impact on the system performance, thereby improving the accuracy of the retransmission users, preventing the occurrence of HARQFAIL and improving the entire performance of the system. |
