  • Patent number: 8386901
    Abstract: A transmitting apparatus transmits a plurality of data packets to a receiver in a communication system, by transmitting one or more data packets from a list of data packets to be transmitted, and determining whether an acknowledgment is received for each transmitted data packet. When it is determined that an acknowledgement has not been received for at least one data packet, referred to as an unacknowledged data packet, the apparatus selects one or more additional data packets from the list of data packets to be transmitted, generates one or more parity packets by encoding a block of data containing a combination of the selected one or more additional data packets and at least one unacknowledged data packet using a forward error correction scheme, and transmits at least one of the generated parity packets.

  • Patent number: 8325643
    Abstract: The invention pertains to a method for determining a sequence of access (300) to a communications network (100) by a plurality of nodes (101, 102, 103, 5 104, 107) of said communications network (100) in the context of the broadcasting of a data content by a transmitter node (101) to a set of receiver nodes (103, 107, 104, 102), at least one receiver node (102, 104) having to receive said content by means of another receiver node (103, 107), called a relay receiver node.

  • Publication number: 20090271681
    Abstract: The invention relates to a method for transmitting a plurality of data packets to a receiver in a data communication system. The method comprises the steps of transmitting one or more data packets from a list of data packets to be transmitted (300); determining whether an acknowledgment is received for each transmitted data packet (301), and further comprises the following steps executed when it is determined at the determining step that an acknowledgement has not been received for at least one data packet, referred to as an unacknowledged data packet: selecting one or more additional data packets from the list of data packets to be transmitted (302); generating one or more parity packets by encoding a block of data containing a combination of the selected one or more additional data packets and at least one unacknowledged data packet using a forward error correction scheme (304); and transmitting at least one of the generated parity packets (305).
