FEEDBACK-BASED RETRANSMISSION OF BROADCAST NETWORK CODING ENCODED PACKETS

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may broadcast a first set of network coding encoded packets for reception by a plurality of receivers, and receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that one or more receivers of the plurality of receivers did not successfully receive a quantity of network coding encoded packets that satisfies a decoding threshold associated with recovering the plurality of source packets, and a first subset of network coding encoded packets of the first set of network coding encoded packets that were not successfully received by at least one receiver. The transmitter may broadcast a second set of network coding encoded packets. The second set of network coding encoded packets may include at least the first subset of network coding encoded packets. Numerous other aspects are provided.
