Abstract: Systems, methods, apparatuses, and computer program products for conditional hybrid automatic repeat request (HARQ) acknowledgement (ACK). For instance, a user equipment (UE) may estimate, during reception of a downlink transmission with x repetitions, an amount of extra energy that may be needed to help ensure successful decoding. The UE may then express this estimate as a quantity of repetitions (y) needed for successful reception, and may inform the radio access network (RAN) of this quantity (e.g., at least one round-trip time (RTT) before the last repetition of the x repetitions is sent). The RAN may handle this message as a conditional positive ACK. The RAN may send the quantity of repetitions y, and may implicitly assume an ACK for that TBS after sending the y repetitions. The RAN may send the next transport blocks (TBS) for that HARQ process after completing transmission of they repetitions.
