Systems, methods, and devices for controlling transport of ratelessly coded messages are disclosed herein. User equipment (UE) may be configured to receive a data object using a plurality of radios having distinct radio protocols. The data object may divided into a plurality of segments, and the segments may be encoded with a random linear network code before transmission. The random linear network code may permit the UE to reassemble each segment from any large enough set of encoded packets. The UE may use delivery control messages with very low overhead to control the flow of packets for each radio. The UE may control the number of packets received for each segment without specifying which particular packets should be sent. The transmitters may transmit the packets with very little overhead, and encoding information for the packets may be included in the packets in a compact form.
