According to the present invention, an ACK/NACK channel, like a physical HARQ indicator channel (PHICH) in long-term evolution (LTE), is designed in a new radio access technology (NR) system. Specifically, a base station (BS) receives uplink (UL) data from a UE, maps a resource for an ACK/NACK channel, which is used to transmit the ACK/NACK as a response to the UL data, to at least one control channel element (CCE) or at least one resource element group (REG), and transmits the ACK/NACK to the UE. The ACK/NACK channel is multiplexed with a physical downlink control channel (PDCCH) in the at least one CCE or the at least one REG."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for designing ACK/NACK channel in wireless communication system","description":"A method and apparatus for transmitting an acknowledgement/non-acknowledgement (ACK/NACK) in a wireless communication system is provided.
