1. A method for wireless communications at a network node, comprising:
transmitting, to a plurality of user equipments (UEs) in accordance with a network coding termination scheme in which the network node terminates packet encoding once a decodability threshold is satisfied for each of the plurality of UEs, a first set of network encoded packets that are associated with a set of packets, wherein transmission of the first set of network encoded packets is part of a broadcast, to the plurality of UEs, of information from the set of packets;
receiving feedback that indicates, for each of the plurality of UEs, a number of successfully received network encoded packets of the first set of network encoded packets; and
transmitting one or more additional sets of network encoded packets associated with the set of packets, a first of the one or more additional sets of network encoded packets being transmitted based at least in part on the number of successfully received network encoded packets failing to satisfy the decodability threshold, and others of the one or more additional sets of network encoded packets being transmitted based at least in part on a failure to satisfy the decodability threshold for respective previous transmissions, wherein transmission of the one or more additional sets of network encoded packets continues until the decodability threshold is satisfied for each of the plurality of UEs.
