Abstract: Methods and apparatuses are provided for performing communication in a wireless communication system is provided. A number of hybrid automatic repeat request (HARQ) processes is set as N. The N is a natural number, one value within a maximum value, 16, and set based on a configuration of a base station (BS). Downlink control information (DCI) is received including a 1-bit HARQ-acknowledgment (HARQ-ACK) feedback request for all of N HARQ processes. HARQ-ACK information associated with all of the N HARQ processes is identified, based on the received DCI. A number of bits for the HARQ-ACK information is defined based on xN by the configuration, and the x is a natural number. The HARQ-ACK information is transmitted to the BS.
