1. A method of receiving a downlink channel by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, in a first reception time, a first physical downlink shared channel (PDSCH) associated with a first hybrid automatic repeat request (HARQ) process among a plurality of HARQ processes;
transmitting, in a first transmission time, a first HARQ-acknowledgement (HARQ-ACK) for the first PDSCH associated with the first HARQ process; and
receiving, in a second reception time, a second PDSCH for a same HARQ process identifier (ID) as the first HARQ process of the first PDSCH,
wherein the second PDSCH for the same HARQ process ID as the first HARQ process of the first PDSCH is a PDSCH scheduled by downlink control information (DCI), and
wherein receiving the second PDSCH for the same HARQ process ID as the first HARQ process of the first PDSCH comprises:
receiving the second PDSCH, for the same HARQ process ID as the first HARQ process of the first PDSCH, in the second reception time which is after the first transmission time, based on the first HARQ-ACK being not subject to HARQ deferral; and
receiving the second PDSCH, for the same HARQ process ID as the first HARQ process of the first PDSCH, in the second reception time which is 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.
