The invention discloses a collaborative transmission method for a wireless broadcasting multicast service. The method comprises the steps that: A, a control node controls an information resource to transmit a broadcasting multicast service data packet to a cluster user; and B, the control node selects one or more cluster members to retransmit the data packet to the cluster user who does not receive the data packet correctly in a cluster. When the method is used, information source broadcast is only required to ensure that each data packet is at least correctly received by one cluster user in the cluster, the cluster user who correctly receives the data packets in the cluster can retransmit the data packets to the cluster user with a packet error till all the users correctly receive all the data packets. The retransmission of the broadcasting multicast service data packet is mainly carried out among the cluster users, so that the broadcasting multicast information retransmission times of the information source are greatly reduced, and the energy consumption of the information source is reduced; meanwhile, network encoding technology is adopted for the retransmission among the cluster users, so that the cast brought by retransmitting each wrong data packet in the traditional scheme is saved and the frequency spectral efficiency and the throughput of a system are improved.
