1. A method for wireless communication at a user equipment (UE), comprising:
receiving, as part of a broadcast from a network node, a first subset of one or more network encoded packets;
decoding the first subset of one or more network encoded packets as a first subset of one or more successfully decoded packets;
receiving, via a plurality of sidelink connections with a corresponding plurality of UEs, a second subset of one or more successfully decoded packets forwarded after successful receipt and decoding by the plurality of UEs from the network node;
determining, based on the first subset of one or more successfully decoded packets and the second subset of one or more successfully decoded packets, a combined set of one or more successfully decoded packets from the network node; and
transmitting feedback to the network node, wherein the feedback indicates a combination of the first subset of one or more successfully decoded packets and the second subset of one or more successfully decoded packets.
