In some examples of the techniques described herein, a network entity may transmit a last transmission indication for a channel grant. The last transmission indication may indicate a last transmission (e.g., last packet of a retransmission) of a current data transmission to be communicated. In some approaches, the last transmission indication may allow a user equipment (UE) to improve a residual physical downlink shared channel (PDSCH) block error ratio (BLER) by prioritizing handling of a last transmission. Additionally, or alternatively, the UE may increase memory (e.g., buffer) utilization efficiency by deleting data stored for retransmission. In some examples, the UE may reduce power consumption by skipping a retransmission timer in connected mode discontinuous reception (C-DRX) without a forthcoming retransmission. In some scenarios, the UE may utilize the last transmission indication to determine whether received data corresponds to a retransmission or to a new transmission.
