1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a configuration indicating a number N of hybrid automatic repeat request (HARQ) processes used for downlink transmissions;
receiving downlink control information (DCI) format 1-1 including a 1-bit HARQ-acknowledgement (HARQ-ACK) feedback indication for all of the N HARQ processes indicated by the configuration;
identifying HARQ-ACK information associated with all of the N HARQ processes indicated by the configuration, in response to receiving the DCI format 1-1, wherein a number of bits for the HARQ-ACK information is identified based on the N indicated by the configuration, and wherein HARQ-ACK information for a transport block (TB) for a HARQ process is set to a negative acknowledgement (NACK) in case that the HARQ-ACK information for the TB for the HARQ process is absent; and
transmitting the HARQ-ACK information through a physical uplink control channel (PUCCH) to the base station,
wherein, based on the DCI format 1-1 including the 1-bit HARQ-ACK feedback indication for all of the N HARO processes. the DCI format 1-1 requests the HARQ-ACK information associated with all of the N HARQ processes and does not schedule a data transmission.
