1. A method of wireless communication at a network coding (NC) encoder, comprising:
transmitting a packet encoding a plurality of transport blocks previously transmitted by one or more transmitting devices;
receiving a plurality of acknowledgments (ACK) or negative acknowledgments (NACK) for the plurality of transport blocks from a plurality of user equipment (UEs);
determining, for a respective transport block of the plurality of transport blocks encoded in the packet, whether the respective transport block has satisfied an ACK condition based on the plurality of ACKs or NACKs from the plurality of UEs; and
transmitting an acknowledgment message to the one or more transmitting devices for at least the respective transport block, the acknowledgment message indicating an ACK if the respective transport block has satisfied the ACK condition or a NACK if the ACK condition has not been satisfied at an expiration time after transmitting the packet.
