Systems, methods, and devices for controlling transport of ratelessly coded messages

摘要

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.

1. A User equipment (UE) configured to communicate with a plurality of transceivers using a plurality of distinct radio protocols, the UE comprising a processor configured to:
transmit a request for a first plurality of packets from a first transceiver over a first radio protocol and a request for a second plurality of packets from a second transceiver over a second radio protocol, wherein the first and second plurality of packets are derived from a current segment of a common data object; process at least a portion of the first plurality of packets received using a first radio of the UE using the first radio protocol and at least a portion of the second plurality of packets received using a second radio of the UE using the second radio protocol, the first plurality of packets and the second plurality of packets received simultaneously and in parallel by the first radio and the second radio, wherein the first transceiver encodes the portion of the first plurality of packets using a linear network code and the second transceiver encodes the portion of the second plurality of packets using the linear network code; transmit a semi-termination message to the first transceiver, wherein the semi-termination message requests the first transceiver cease transmission of packets derived from the current segment; and receive additional packets derived from another segment from the first transceiver.
