## Abstract

Methods and apparatuses are provided for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information by a terminal in a wireless communication system. A method includes receiving one or more transport blocks, determining a number of HARQ-ACK bits in response to the one or more transport blocks, determining an uplink resource for transmission of the HARQ-ACK bits, and transmitting the HARQ-ACK bits by using the determined uplink resource, wherein the uplink resource is associated with a first modulation order or with a second modulation order, different from the first modulation order, depending on the number of HARQ-ACK bits.
