Network coding with dynamic redundancy overhead

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more processors;
• one or more memories coupled with the one or more processors;
• and
• instructions stored in the one or more memories and executable by the one or more processors to cause the apparatus to:
• attempt to receive each of a first set of network coding encoded packets, the first set of network coding encoded packets using a first redundancy overhead;
• estimate a failure rate based at least in part on a quantity of the first set of network coding encoded packets that are successfully received when attempting to receive each of the first set of network coding encoded packets;
• transmit a message related to a second redundancy overhead based at least in part on the failure rate associated with the first set of network coding encoded packets exceeding a threshold failure rate, wherein the failure rate associated with the first set of network coding encoded packets using the first redundancy overhead is based at least in part on a quantity of network coding encoded packets, from the first set of network coding encoded packets, that the UE is unable to receive, wherein the second redundancy overhead is different from the first redundancy overhead, and wherein transmission of the message related to the second redundancy overhead is based at least in part on the failure rate;
• and
• receive, after transmission of the message, one or more second sets of network coding encoded packets transmitted with the second redundancy overhead.
