A method of packet retransmission in a communications system having a plurality of user devices and at least one network device involves broadcasting a multimedia broadcast multicast service transmission to the plurality of user devices. One or more of the user devices which failed to receive the complete transmission correctly send a request for retransmission to the network device and the network device retransmits requested packets of the original transmission on a different transmission channel to the original broadcast channel.
