1. An encoder device for wireless communication, comprising:
at least one processor; and
at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to cause the encoder device to:
receive, from a network entity, in accordance with a buffer configuration of the encoder device or a buffer report associated with the encoder device, an indication of a set of transport blocks (TBs) for a network coded sidelink retransmission, the set of TBs associated with one or more sidelink transmissions;
receive, from the network entity, an indication of one or more uplink control channel resources that are to be used for providing feedback associated with the set of TBs, wherein the one or more uplink control channel resources include an uplink control channel resource associated with:
providing an indication of whether the set of TBs are stored in the buffer of the encoder device, or
providing feedback indicating whether the network coded sidelink retransmission is successfully decoded by one or more receivers; and
transmit the network coded sidelink retransmission based at least in part on encoding TBs, included in the set of TBs, that are stored in a buffer of the encoder device.
