Abstract: A user equipment (UE) may determine a first transmission time for a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for a first downlink channel associated with a first HARQ process; and receive a second downlink channel associated with the first HARQ process. Receiving the second downlink channel for the first HARQ process may include: receiving the second downlink channel after the first transmission time based on the first HARQ-ACK being not subject to HARQ deferral; and receiving the second downlink channel after a second transmission time based on the first HARQ-ACK being subject to the HARQ deferral and the first transmission time being determined by the HARQ deferral from the second transmission time earlier than the first transmission time.
