Abstract: Provided herein is a method and apparatus for configuring a physical uplink control channel (PUCCH) resource in a wireless communication system and, most particularly, in a new radio access (NR) technology. More specifically, when and/or for which operation the default PUCCH resource is being used may be defined. For example, a wireless device may receive information on a default physical uplink control channel (PUCCH) resource, and the wireless device may transmit uplink control information (UCI) to a gNB by using the default PUCCH resource, only before establishing a radio resource control (RRC) connection with the gNB.
