1. A processor of a first device configured to perform operations comprising:
generating, for transmission to a second device, a medium access control (MAC) protocol data unit (PDU) comprising a plurality of MAC subPDUs, each MAC subPDU comprising at least one of a subheader, a MAC service data unit (SDU) or a MAC control element (CE);
receiving, from the second device, feedback indicating that the MAC PDU was received incorrectly;
determining that a partial transmission scheme criteria is satisfied;
generating, for transmission to the second device, an indication that the partial transmission scheme is to be used to retransmit the MAC PDU;
generating, for retransmission to the second device, the MAC PDU using the partial transmission scheme; and
generating, for transmission to the second device, a partial transmission table, wherein the partial transmission table is constructed based on, at least, a delay budget for one of the MAC SDUs or MAC CEs in the MAC PDU.
